"Sorry, Lieutenant, but without a subpoena we're breaking the law," said O'Brien.

"OK. I guess we have no choice." Driscoll nodded to Liz Butler, who stepped aside to place a second call to the DA's office.

Driscoll's cell phone rang. It was Margaret. Driscoll got right to the point.

"How fast can you get to the batcave?"

"Ten minutes."

"OK. Ten minutes it is."

A smile creased O'Brien's face. "We've located him. He just called a cab company in Easthampton. Gerhard better get here fast."

Chapter 28.

Assistant DA Andrea Gerhard held out her hand and smiled. "Nice to see you again, Lieutenant."

Driscoll was taken by surprise. He had no recollection of ever meeting the woman. She was thirtyish, with blond curly hair and sparkling blue eyes. She wore a smart black business suit, with a long jacket that pulled in at the waist and flared out at the hips. Sharp dresser Sharp dresser, he thought.

"I can see by your expression that you don't remember me. We met at the District Attorney's Homicide Conference about a year ago."

"Why, Ms. Gerhard, of course I remember you," he lied. "There's no way I could forget a pretty face such as yours." He found himself flirting, but then was interrupted by Danny O'Brien.

"Lieutenant, the subpoena?"

"Andrea. May I call you Andrea?"

She nodded.

"I'm not sure how much of this Liz discussed with you by phone, but what we need is a judge-ordered subpoena to triangulate, to track cell sites and trace outgoing calls from a missing cell phone."

"Is it missing, or stolen?"

"At this point, we don't really know for sure. All we do know is that the phone belonged to a homicide victim, and that someone is still using it."

"That's good enough for me. I'll call Judge Fulton. He used to be a prosecutor in our office. I'm sure I can convince him to sign off on it. I'll need one of your detectives to act as the affiant and swear to the subpoena's veracity."

"Absolutely. Liz, you're to assist Ms. Gerhard."

"Now if you'll guide me to a desk and a telephone..."

"Danny, OK to use this as an outgoing line?" Driscoll was holding a receiver to what appeared to be a simple telephone, but since he was inside the batcave, he thought it best to ask.

"Of course," said O'Brien.

Driscoll handed the receiver to Gerhard.

"Thank you, Lieutenant." There was that smile again.

Driscoll turned his attention back to Danny O'Brien. "What's the last read you have on him?"

"Same as before. Easthampton."

"OK. I want to know the minute it changes."

Margaret walked through the last of the security doors and joined Driscoll.

"What do we have, John?"

Driscoll quickly explained the situation.

"What do you need me to do?

"Get on the horn to Cedric. Have him start putting together a roster and get a tactical plan going. I want everyone held until I say go. We'll need all the teams in the field on this one, and I want everybody packed and ready to move when I give the order."

"I'll get right on it."

"He's moving," O'Brien shouted. "He just hit cell sites in Westhampton, Speonk, and Mastic."

"He's headed back toward the city," said Driscoll.

"He must be in a car," Vittaggio added.

"Judge Fulton just approved the warrant. You're good to go," said Gerhard. "Now all I need to do is fax the details to my boss."

O'Brien pointed to the fax machine.

Margaret poked Liz. "Who's that?" she said.

"Assistant DA. She's writing the warrant for us."

Margaret eyed the pretty blonde. Why was she sensing competition?

"Lieutenant, we should be moving," said Liz Butler.

"My next order of business. Liz, you and Luigi take the Southern State Parkway. Margaret and I will take the Long Island Expressway. Danny, get somebody to drive that van, with you and the triangulater following me."

O'Brien had his ear to the phone. "He's passed Patchogue, Sayville, and Oakdale already."

"Traffic must be light."

"Islip and Bayshore," shouted O'Brien.

"He's not in a car," said Driscoll. "He's on the Long Island Railroad. Those are railroad stops."

Driscoll caught Margaret's eye. "Cedric has extra manpower set up if you need it," she said.

"That's good news. Now call the Long Island Railroad police. We have to stop that train before it hits Jamaica. If he makes it there, we'll never find him. What's the last stop before Jamaica?"

"Lynbrook," someone hollered.

"Margaret I don't care what you have to tell them, but have that train stopped at Lynbrook."

"Liz, Luigi, go. Meet me at the Lynbrook station. Danny, get to the van and get ready to move. You're to keep me informed by phone."

Driscoll turned to leave with Margaret.

"Wait," said Andrea Gerhard. "Here's my card. Call me and let me know what happens. I have to go and file the warrant now, but you can call me anytime. My home number's on the back."

Driscoll took the card and thanked her. His eyes followed her as she walked away. As he turned back, he caught Margaret's glare. Men! Men! was her thought. was her thought. You shouldn't ever trust them You shouldn't ever trust them. Why did she feel so vulnerable? So violated?

"When your mind is back on the business of catching the bad guy, you'll be happy to know that I got through to the Long Island Railroad police. They'll hold the train at Lynbrook until we get there. I also gave Cedric the heads up. He's sending over a team."

"That's good news. Let's go. I'll drive."

They drove in stony silence for a good five minutes. Driscoll made the left from Darcy Street and headed onto the interchange that would take them to the Grand Central Parkway. He hit the flashing lights and eased into the left lane.

"Margaret, call the Chief of D's and put us out of the city," he said, breaking their silence.

"Yes sir, Lieutenant, anything you say."

"All right, Margaret, what's the attitude for?" He knew full well what was wrong, but decided to let her air it out.

"There's nothing wrong. I'll make the call right now."

"C'mon, let's not let personalities get in the way of this."

"Personalities!" she exploded. "'You can call me anytime. My home number's on the back,'" she said, mimicking Andrea Gerhard's voice. "The bitch! She doesn't even belong in a police facility, and she has you kissing her ass."

"I was not kissing her ass. We needed her to write the warrant. Without it, we had nothing. Sometimes you have to play ball."

"She wanted you to play ball, all right." Margaret folded her arms and stared out the passenger-side window.

"Margaret, if that upset you, I'm sorry." He reached over and touched her shoulder. She gave him a side-long glance and brushed his hand away. Silence returned as Driscoll gave her a moment or two to cool down.

Margaret finally spoke. "I don't think you should let the Chief of D's know we're out of the city. If you do, Santangelo will want to know why. Are you ready to let him in on this?"

"You're right. He'll just screw things up. We'd be better off running silent until we know exactly what we have."

They were moving onto the Southern State Parkway from the Cross Island when the car phone rang.

"Lieutenant, it's Liz. The railroad cops have the train stopped at Lynbrook. I had the conductor make an announcement that there was trouble on the track ahead, and that it should be cleared in a few minutes. What do you want us to do?"

"Stand by, Liz, we're only a few minutes out. Hold everybody till I get there."

"There's a railroad police captain here. He wants to know what's going on."

"Tell him you don't know, and that your boss is on his way and will explain things when he gets there."

"OK, Lieutenant. I'll hold him off as long as I can. Cedric's reinforcements are here, and Danny just pulled up in the van."

"That's good. I'm just passing Exit 14 on the Southern State. We're five minutes out." Driscoll hung up and pulled off the parkway onto Franklin Avenue, heading south. He made his way to the Long Island Railroad parking lot on Sunrise Highway, where he killed the lights and pulled up beside the TARU van. Margaret and he then got out of the cruiser and climbed the stairs to the platform.

Liz and Luigi were talking to a team of Long Island Railroad uniforms when Driscoll approached.

"Captain, this is Lieutenant Driscoll, my boss," said Liz. "Lieutenant, this is Captain Warner of the LIRR police."

"What's this all about?" asked Warner.

Driscoll motioned for the captain to walk away so that they could talk privately.

"Cap, we think we may have a homicide suspect on the train. We're not sure what he looks like, and I think the uniforms might scare him away. He's got our victim's cell phone, so what I planned on doing was put my people in every car, dial the number, and see whose phone rings. He has no idea that we know about the phone, so he has no reason not to answer it."

Warner was silent a minute, twisting his walrus-like mustache with his right hand. "OK, that sounds like it'll work. I'll keep my men on the perimeter in case anything goes wrong. Try not to kill anybody on my train, will ya?" Warner did an about-face and headed toward his men. Driscoll looked skyward and thanked God there were still some reasonable men left in other police departments.

The Lieutenant then gathered his people around him and assigned each team one of the four cars. He was about to tell Margaret to dial the number when Danny O'Brien appeared with what looked to be a satellite antenna with two prongs sticking out of its middle. On his head, he wore a pair of headphones.

"Lieutenant, I'm triangulating him now. He's on the phone." O'Brien passed the first two cars and stopped at the third.

"He's in here. In here!" O'Brien said, desperately trying to keep his voice down.

Liz Butler and Luigi Vittaggio took the front door, and Driscoll and Margaret, the back. On Driscoll's signal the conductor opened the doors, and all four detectives entered the car. There in the middle of the car sat an unkempt-looking white male with his feet on the seat in front of him, talking on a cell phone. O'Brien pointed excitedly.

Butler and Vittaggio approached from the front, and Driscoll and Margaret closed in from behind. Liz Butler stood before him and said, "Hi." As he looked up, Vittagio stuck his gun in the man's ear, and Driscoll grabbed both of his arms.

"Police," they all screamed at once.

Driscoll and Butler got the man's hands behind his back and cuffed him. Margaret took the phone and pressed the button that displayed the phone's cell number.

"Bingo!" she said. "We got him."

"Wait! Wait!" The man protested. "It's OK. It's my girlfriend's phone."

"Get him out of here," said Driscoll, staring down an assembly of alarmed passengers. "Liz put him in my car and sit with him. Margaret, grab his stuff and meet me at the car."

Margaret picked up the bag next to the once-occupied seat and walked out of the car.

"We're gonna search your belongings," said Driscoll.

"OK, OK. Whatever."

Driscoll found Warner at the end of the platform and walked over to him. "Thanks, Cap. I appreciate all your help."
