"No. I don't like the fact that there are so many people back here. Too much opportunity for distraction."

"Perhaps all these people will make it impossible for Evan to steal the diamond," she said, feeling more confident by the minute. What could happen in this crowded room with so much security?

"I doubt it. He'll make an attempt; I'm sure of it."

She wished J.T. didn't sound so skeptical. "Well, it's almost over," she said, watching the electronic board on this side of the wall. It showed the next lot up-the Benedetti diamond.

"So what happens?" J.T. asked. "Someone puts the diamond on the revolving door and then it goes into the showroom?"

"Right."

"And the guards are all back here?"

"There are guards at the showroom door and also the front door," she said, wondering why he was still so tense. "It's impossible, J.T. There is no way Evan can grab that diamond and walk out of here with it." She paused. "You don't think he's going to pull out a gun and take the diamond by force, do you? I don't want anyone to get hurt."

"No. Too risky and too messy," J.T. said.

Christina looked up as the light flashed for the next lot. Russell opened the glass case and lifted out the necklace. "May I?" Stefano Benedetti asked as he stepped forward.

Russell nodded and handed Stefano the necklace. Christina held her breath as Stefano examined the diamond. He held it up to the light and then slowly gave a nod of approval. He stepped up to the revolving door, waiting patiently as someone removed the previous lot. An assistant placed a black velvet oval display form on the turntable. Stefano attached the necklace to the display. It looked stunning and magnificent. The crowd would go crazy when they saw it.

Christina glanced up at the television screen. The auctioneer called for the grand finale, the lady of the evening, the spectacular Benedetti diamond. Stefano hit the button to send the diamond into the showroom.

Christina looked back at the screen. She could hear the murmurs of the crowd over the audio, but it wasn't until the gasps of shock were followed by loud cries that she realized what they were seeing. The diamond was no longer on the display form. In its place was a candy necklace.

"What the hell?" J.T. swore.

Stefano and Russell rushed toward the revolving door, their hands coming down together on the button that would bring the turntable back into the workroom. Moments later the candy necklace was in Stefano's hand.

Russell barked into his radio transmitter to lock down the building, not to let anyone in or out until further notice. Christina was jostled as people rushed around the room in a mad, chaotic, and purposeless frenzy. She didn't know what to do. The diamond was gone. It had disappeared right in front of them. Who could have taken it? How had they done it?

As she looked around, she realized that Stefano, Russell, Luigi, and Jeremy had left the room. Even J.T. was gone. Where the hell did he go? Did he know something she didn't? Had he finally figured out who Evan was?

She headed out the door, down the long hallway, and back to the showroom. Pandemonium greeted her. Several buyers flagged her down, demanding to know what had happened to the diamond and why they couldn't leave. Some of them had just authorized purchases worth thousands of dollars. They were furious and insulted, and she couldn't blame them. But she also had absolutely no authority to let anyone out of the building. She placated them with useless promises that everything would be resolved shortly, when in fact she had no idea what was going to happen next.

She ran into Kelly at the bottom of the stairs.

"Did you see what happened?" Kelly asked, her eyes lit up with excitement.

"I was in the back room when the necklace was put on the turntable," Christina said. "I saw it go into the showroom with my own eyes. How could it disappear like that?"

"I have no idea. I was in the showroom. It seemed to take forever for the door to turn, slower than usual, I thought. In fact, I wondered if we were trying to build excitement by slowing down the speed of the turntable."

Had it been slower? Christina wondered. There was a small space between the two rooms where the revolving door turned, but she couldn't imagine it was big enough for a human being to stand in. She'd let the others figure that out. She had to concentrate on her end, which involved keeping her job and making sure her father wasn't on the premises. "Have you talked to Alexis?" she asked Kelly. "What are we supposed to do now?"

"I'm trying to find her. I think she and Sylvia went upstairs. I know Russell has the building in lockdown. No one is getting out of here with that diamond."

If they weren't already gone, Christina thought. She headed up the stairs, checking the gallery for her father or J.T., who wasn't anywhere to be seen either. She really hoped he had a lead on Evan.

Next, she ran up the stairs to the third floor. The hallway was fairly empty, so she was more than a little surprised to hear voices coming from her office. She paused outside the door, wondering who was inside.

"It's clear that Christina's involved," Alexis said. "Look at this."

Christina's heart came to a thudding stop. Involved? What was going on?

"I thought her father was out of the picture," Jeremy replied.

"Obviously not," Alexis said. "She must have been working with him to steal the diamond. He called me earlier, left a message on my voice mail that he was going to put it back where it belonged. You know how he thinks he's some Robin Hood, rescuing artifacts from their greedy owners. That has to be what this is about."

"We need to isolate Christina until we know exactly how she's involved," a third man interrupted. "She was in the workroom when the diamond disappeared."

It was Russell, Christina realized. And they were talking about her as if she'd had something to do with taking the diamond. Why would they think that? She'd been standing in full view of Russell and Jeremy. In fact, she'd been the one farthest away from the diamond. So where was the suspicion coming from? Was it just the supposed phone call from her father? What were they doing in her office? What else were they looking at? Had her father left something in her office, a note, a message?

Realizing they could walk out at any second, she ran down the hall as quickly and as quietly as she could. It suddenly hit her that she was in very big trouble, and if she wasn't careful, she was going to be railroaded straight to prison. She had to stay free long enough to find her father and the diamond.

J.T. looked at every single face he passed as he strode through the auction house, the old, the young, the men, and even the women. Evan was here. He had somehow, in some sleight of hand, managed to steal that necklace. J.T. still didn't know how he'd done it. Maybe there was a way to get in between the panels, so that when the turntable rotated, a switch could be made. He returned to the showroom and went over to study the door. He pushed the button and it slowly revolved. As the door moved, he checked the space in between. It seemed impossibly narrow for anyone to get in there.

How could the diamond have disappeared in the minute it took for the panel to turn?

Had someone been standing near the panel inside the showroom? A man, he recalled, wearing the same navy blue suit coat as the auctioneer. Had it been Evan? But wouldn't someone have seen him grab the necklace and run?

Racking his brain, J.T. tried to remember what he had seen on the monitor. He'd been watching the screen, as had Christina, waiting to see if anyone in the showroom would rush the diamond or if the auctioneer would make a sudden move, if someone would ask to examine the diamond up close. He'd anticipated any number of possible scenarios, but not this one.

Glancing around the room, he tried to place everyone in the spot in which they had been standing when the diamond had gone onto the display. Russell, Luigi, Jeremy, and Stefano had been together by the table, which was now empty. The diamond had been in a glass case. Two other employees, a man and a woman, had been packing up some art on the adjacent table. Christina and he had moved away after she'd checked the diamond. They'd been standing in front of the monitor, which was now off. He knew he was missing something important, but whatever it was, it was just out of reach.

He went over the four men again in his mind. Russell, Luigi, Jeremy, Stefano. A Barclay's employee had set the necklace display form on the turntable. Stefano had placed the necklace on the display form. Why him? Sure, it was his necklace technically, but why hadn't the Barclay's employee done the deed? Had it just been professional courtesy? Jeremy Kensington had been standing right there, overseeing the moment.

J.T. wasn't sure what he thought of Jeremy Kensington. The hit-and-run accident the night before, the tie-in between Alexis and David, the fact that Jeremy's wife might have been cheating on him-what did it add up to? Was Jeremy involved in some insurance scam? Was there a policy on the diamond? Was that why he'd taken it upon himself to be right there when the diamond was placed on display?

J.T. would have to ask Christina if it was common for Jeremy to be backstage. It seemed more likely that he would have been out in the showroom, overseeing the bidding.

And what about Alexis? Where was she when the diamond went missing? They'd run into her and Sylvia as they'd entered the room, but he wondered where the two women had gone after they'd left.

"J.T." Christina burst into the back room, her voice breathless, her eyes panicked. "You have to get me out of here. You're the FBI. They'll let me walk out with you. Please, we have to hurry."

She grabbed his arm, but he stopped her. "Whoa, what's going on, Christina? What's wrong?"

"I can't explain. There's no time. Someone is setting me up to take the fall for the theft. Everyone is upstairs in my office-Russell, Alexis, Jeremy, God knows who else. They'll be down here in a minute. You have to get me out of here."

For a split second J.T. wondered if she was playing him. Was this the final move in the game? Was she working with Evan? Or with her father? He hated to think so.

"You have to trust me," she said, obviously seeing the doubt in his eyes. Her agitated fingers twisted the sleeve of his coat. "I haven't done anything wrong. But someone wants to blame me for everything. I can't let that happen. Please, J.T. Help me."

She was asking him to cross a very big line. If he was wrong about her, all hell could break loose. He could ruin his career, the rest of his life. If she was telling the truth, he needed to help her. He wanted to help her. And deep down, he knew no matter how much he argued with himself, there was no way he could resist the terrified plea in her beautiful green eyes. "All right. But if you're messing with me, Christina, you will be very sorry."

"The employees' entrance is the closest," she said, taking his hand.

"Fine, but don't look so nervous. Take a breath. Calm down. Otherwise you're going to raise suspicion."

She paused a moment to draw in several deep breaths. "Okay, I'm ready. Let's go."

When they reached the employee entrance, two security guards barred their exit. Christina greeted one of them by name. "Hi, Sam. This is J. T. McIntyre. He's with the FBI. We have to go down to his office."

Sam nodded. "Sorry. Mr. Kenner said no one goes out."

"You can search us," J.T. said, "but Ms. Alberti and I have to continue with the investigation off the premises. You can call Mr. Kenner, check it out."

Sam hesitated, casting a quick look at his partner, who simply shrugged. "Okay, but we'll have to search your purse, Ms. Alberti."

Christina let Sam rifle through her purse while J.T. turned his pockets inside out for the other guard. A few minutes later they were cleared to leave. J.T. kept a hand on Christina's arm as they walked quickly back to his car. He could feel her tension as if it were his own. She looked over her shoulder every other second, as if she expected someone to come running after them. Fortunately, their parking space down the block allowed them to leave without raising any flags. They were two miles away before she let out a sigh.

"God," she murmured, "I can't believe this is happening. How did that diamond disappear right in front of us?"

"I've been trying to figure that out."

She ran a hand through her hair. "I keep seeing that turntable come around and the candy necklace on the display."

"That touch was pure Evan," he said.

"But how did he do it?"

"That's what we have to find out. First, tell me where we're going."

"Do you remember how to get to my father's house?"

"I think so. Why? Is he there? Have you heard from him?"

"I haven't heard a word, but I can't think of where else to go. I have to find him so I can clear his name and mine. Maybe he left some clue as to where he is."

J.T. turned left at the next corner. "Let's hope so. Now start talking. Tell me what happened back at Barclay's."

"I went upstairs to my office. I heard Alexis, Jeremy, and Russell talking about how I must be working with my father, and something was obvious proof of that. Russell said I needed to be found and questioned as soon as possible." She shook her head in confusion. "I don't know what they discovered in my office, but it must have been incriminating in some way. They think I did this. They think I stole the diamond or that I helped my father steal it."

"He makes a good scapegoat. So do you," J.T. said, computing the facts. "Evan set you both up."

Christina crossed, then uncrossed her legs, fidgeting restlessly in her seat. "What I don't understand is how anyone could get out of the auction house with that diamond. The doors were locked immediately. We were searched before we left. Everyone will be searched. How could Evan get out with the diamond in his hand or his pocket, or in anything for that matter?"

He'd been wondering about that as well. If Evan was responsible for stealing the diamond, then he had an escape route. "There was a moment of indecision," he said, "before Russell called for the lockdown."

Christina sent him a doubtful look. "You think there was enough time?"

"Unlikely but not impossible." J.T. turned left as they neared her father's street. "We'd better make this quick. If Russell calls the dogs on you and your father, this will be the first place they check."

"It will just take a few minutes. We won't stay long."

"I don't suppose you brought a key this time," he said as he parked the car in her father's driveway.

"Actually, I did. I put it on my key ring yesterday just in case I had to come back here."

As they entered the house Christina called for her father several times, but no one answered. She headed straight for the study and the safe hidden behind a painting. In a few seconds she had it open. "I checked this the other night and nothing was here, but maybe he came back in between then and now." She stuck her hand into the safe and pulled out an envelope with her name on it. "This wasn't here before."

"Read it aloud," J.T. commanded.

She removed the slip of paper and read, "*Christina-I know you're angry with me now. But I had to take the diamond. It is cursed and needs to be returned to its rightful owner. It is more important than you can imagine. I will be in touch when I have made things right, when I have put the diamond back where it belongs. Don't hate me. Love, Dad.'"

She let out a breath, biting down on her lip as she lifted her gaze to meet his. He saw pain and disappointment in her eyes. Her father had let her down big-time.

"You were right," she said. "My father did steal the diamond. I can't believe it's true, but it's right here in black and white."

"Is it? Are you sure that note is legit? Could Evan have written this, too?"

"I don't know." A frown marred her features as she stared back down at the paper. "I was fooled before, but this note sounds just like my dad, the way he thinks, the way he talks. It's pretty much what he said to me yesterday when I saw him at the zoo."

J.T. could see that she believed the note, which made him believe it, too. "Is there anything else in the safe?"

She looked back inside. "Oh, my God, there is." She pulled out a gray wig, letting it dangle from her fingers, as if she couldn't quite believe what it was. "What is this?"

J.T. moved next to her. He reached into the safe and pulled out a fake nose, a pair of thick glasses, and an ID for Howard Keaton, Ph.D. He let out a low whistle. "Look at this." He held up the ID so Christina could read it. "I guess we know how your father got into the auction house."

Christina's jaw dropped, surprise spreading across her face. "Professor Keaton? My father was masquerading as Professor Keaton? How can that be? I talked to him. I looked him in the face. I stood a foot away from him at the preview party. I would have recognized my own father-" She stopped abruptly.

"What did you just remember?"

"Well, now that I think about it, my father did fool me once before. He came to see me right after he left the museum and before I resigned. There was about a week in between when I was trying to fix things. He came into my office dressed as a janitor. I was talking to him for five minutes before he let me know it was him. And then there was that other time-"

"Dammit, Christina, you should have told me this before," J.T. said, cutting her off. "The fact that your father likes disguises would have been helpful to know."

"I didn't think it was important, because I didn't want to believe he would steal the diamond from me. But I was wrong. It didn't matter that this theft would hurt me. It didn't matter to him at all." She threw the wig back into the safe along with the rest of the items and slammed it shut.

"Something is off," he muttered, as she pushed the painting back into place.

"Like what?"

"Too many thieves and not enough diamonds," he said. "Professor Keaton hasn't been at the auction house since Wednesday night, since the smoke bombs went off. He wasn't there today, not as Professor Keaton anyway." J.T.'s mind raced back to Wednesday night, the images from the party flashing through his head. Christina was talking to the professor. He reached up to touch the necklace. It slipped off her neck, landing in his hand. He handed it back to her. The smoke alarms went off. Someone shouted, "Fire!" Everyone went running.

"J.T., what are you thinking?" she asked impatiently.

He blinked, her voice bringing him back to the present. "If your father was impersonating Professor Keaton, and the last time Keaton was at the auction house was Wednesday night when the smoke bombs went off, then he took the diamond that night."

Christina's eyes lit up. "The clasp opened, and he caught the diamond. But he gave it back to me."

"Only he didn't give you the real stone. He gave you a fake, an exact copy. So when you looked at the diamond under your scope and didn't see that flaw you were looking for-"

"It was because the diamond was a fake," she finished. "I think you're right, J.T. My father took the real diamond on Wednesday. He probably had it on him when I saw him at the zoo the next day." She drew in a quick breath. "But if that's true, then who stole the necklace today?"

"Evan."

She met his gaze head-on. "Do you think he has any idea the diamond he stole is a fake?"
