"I told you, Calvin didn't kill his father."

"So you say, but I'm afraid you've been taken in, Mr. Malloy. Calvin was always fiendishly clever, even as a child. Edmund told me stories about the boy ... Well, I'm not one to gossip, but suffice it to say that the child has been an accomplished liar his entire life. I'm not surprised he was able to deceive you, but you must be careful not to let him escape without paying for his heinous crime."

"If he's guilty, he won't escape," Frank assured him.

Potter didn't look convinced, but he didn't press the issue. "I'll have Granger see you out," he said.

"I'm waiting for Mrs. Brandt," he replied, pointedly sitting down on the bench in the hallway.

Potter seemed a bit disturbed by this, but he said, "I'll be in the study if you need anything. Good day."

Potter closed the door behind him. Frank wondered how he felt about working in the room in which his good friend had been murdered. Maybe he enjoyed it. Potter seemed to have been in Blackwell's shadow during the doctor's life. Perhaps he felt he would come into his own now. If he could achieve the same results as Blackwell in healing people, he might gain respect and fame of his own. Unfortunately, Frank didn't think he could. If half of Blackwell's success had been due to his ability to charm people into thinking they were healed, Potter would never be able to duplicate his results.

SARAH DIDN'T KEEP Malloy waiting long. He didn't even look impatient when she found him sitting in the hallway at the foot of the stairs.

"How is she?" he asked, rising to meet her.

"She's sleeping."

"Morphine?" he guessed.

"Yes." She sighed, and let him take her medical bag to carry.

They didn't wait for the butler to show them out.

The street was quiet except for the muffled sounds of the city all around it. She supposed the little park would help with that. Traffic would avoid the square, and the residents probably paid the beat patrolman to make sure no riffraff lingered in the area. In fact, Sarah could see him strolling along the street on the other side of the park.

Malloy saw him, too. "Patrick!" he shouted, getting the man's attention. "I need to talk to you!" He turned to her. "If you don't mind, I have to ask him some questions."

"Of course not," she said, more than eager to hear what Malloy would speak with him about.

The policeman hurried over to where they stood. He was middle-aged and overweight, his stomach bulging over his belt, and by the time he reached them, he was red-faced and out of breath. Unmistakably Irish, his large nose was blotched with broken veins from years of drinking. Malloy took him aside, not bothering to introduce him to Sarah, although he looked eager enough to make her acquaintance and kept glancing over at her curiously during his conversation with Malloy.

Sarah turned away, feigning interest in something in her purse while the two men talked, but she could hear every word.

"You were on duty the day this doctor fellow was killed, weren't you?" Malloy asked.

"Yes, sir, I was. Remember, I was guarding the door when you come in, and I told you what happened."

"Did you see anyone suspicious hanging around that day?"

"Suspicious? What do you mean by suspicious?"

"I mean anybody who didn't belong in the area, or somebody hurrying away, like they were scared or something," Malloy said. Sarah heard the edge of impatience in his voice, and turned her head so Officer Patrick wouldn't see her smile.

"I don't know if I can think of anything like that happening ..."

"You'll not get anything from me but a cuff to the head, Patrick, so give up trying to get me to bribe you. Did you see a boy knocking on Blackwell's door that afternoon around two o'clock?"

"Well, now come to think of it, I did. Couldn't rightly say it was two o'clock, or even the same day, but I recall seeing a boy on somebody's porch in the last few days. Banging on the door, he was. Looked like he belonged on a farm somewhere. From his clothes, I mean. Tried to tell me he had an appointment, but I knew he was just some bummer looking for a handout, so I sent him on his way. That's what I get paid to do, ain't it?"

"I suppose it is," Malloy agreed, not happy at all with this level of cooperation. "Did you see anybody else?"

"When?"

Even Sarah was starting to get annoyed with this Patrick. He might get his cuff on the head from her if he didn't give Malloy some better answers.

"The day the doctor got killed," Malloy said. He sounded as if he were gritting his teeth to keep from shouting.

"I thought he killed hisself," Officer Patrick said. "I saw him, and that's what it looked like to me. I was across the way there when I heard his wife screaming. She run out on the stoop and starts screaming like somebody's trying to kill her, so I come running with my nightstick ready. Wasn't nobody else in the house, though. I looked all around. Her servants come home about then, and they started carrying on, so I had someone telephone the station house. I waited outside until somebody come."

"When you saw Blackwell, did you touch anything in that room?"

"Sweet Mary, no! There was blood everywhere, and any fool could see he was dead. I didn't even go in the room except maybe a step or two. What makes you think somebody killed him?"

"There's some money missing from the house," Malloy told him. "If I find out you took it-"

"I didn't take no money from the house! What do you think I am?" Patrick asked, affronted.

"I just better not find out that you did. Thanks for your help, Patrick," Malloy said, disgust heavy in his voice. "You can go back about your duties now."

"Glad to be of help," he called after Malloy. Then, "Nice to see you, miss."

Sarah bit her lip to keep from smiling when Malloy muttered something under his breath. Malloy touched her arm and they started walking away. Sarah resisted an impulse to wave good-bye to Officer Patrick.

"Was it Calvin you were asking him about?" she asked when they were safely out of earshot.

"Yeah, the boy said he'd come to keep an appointment with Blackwell at two o'clock that day. Potter told me Blackwell had made the arrangements. Calvin said he heard the clock strike, so he knew it was the right time." Many people in the city couldn't afford timepieces of their own and kept track of the hour from the many clock towers in the city.

"And he said the patrolman saw him?"

"He said the patrolman run him off when nobody answered the door to let him in. That's how he can prove he never got into the house at all, so he couldn't have killed his father."

"Officer Patrick confirmed his story, then."

Malloy gave her a pitying look. "Officer Patrick is a stupid drunk who can't tell one day from another. He remembered seeing the boy, but he wasn't even sure whose porch he was on, much less if it was the same day Blackwell was killed. I believe it happened like Calvin said, but Patrick isn't going to be much help in proving it."

"Oh, dear."

"Yeah, oh, dear." Malloy sounded discouraged.

"You seem very interested in solving this case," she tried. She knew police detectives were ridiculously underpaid and had to rely on bribes and rewards to make their living. Consequently, they couldn't afford to waste a lot of time on cases that wouldn't supplement their meager incomes.

"Potter offered a reward," he told her reluctantly.

"Oh, my, I suppose that lets him out as a suspect, then," she said with some disappointment. "I was rather hoping he was the killer."

"He's not one of my favorite people either, especially now that he's dead set on proving that the boy did it."

"It makes sense," Sarah pointed out, playing devil's advocate. "Blackwell had done a terrible thing to his family. The boy must have been very angry. Maybe he even hated his father."

"Maybe," Malloy allowed. "Potter said Blackwell told him the boy was an accomplished liar, too."

"Really? He looked awfully innocent to me, and he seemed genuinely upset today at the funeral. Why would he have had to be a liar?"

"That's an interesting question. I've seen lots of good liars in my time, but mostly they were raised on the streets, making a living any way they could, stealing and lying and cheating, sometimes even killing. But Calvin didn't grow up on the street."

"He would have had a difficult time of it, though," Sarah pointed out.

"He said he went to work very young. His mother took in washing. It was a hard life, but I just don't see him even stealing a loaf of bread, no matter how hungry he might've been."

"But what's this you were telling Officer Patrick about some missing money?" she asked. "Do you think Calvin stole money from his father?"

Plainly, he didn't want to discuss this, but he also knew she wouldn't give up until he told her. "According to Potter, Blackwell was going to give Calvin some money the day he was killed to buy the boy's silence. Calvin was supposed to take the money and go back home to Virginia. The money hasn't turned up, though."

"And if Calvin had gotten it, that probably means he's the killer," she guessed, "but if he did kill his father and get the money, it also doesn't seem likely he'd still be here in the city, does it?"

"That does seem reasonable," Malloy said just to keep from admitting she was right. She knew he hated admitting she was right.

"But you don't think Calvin is the killer, at least."

"No, I don't. He's just too innocent."

"I'm impressed, Malloy. You hardly ever see good in anyone."

"There's hardly ever any good to see," he countered.

"With the people you deal with, that's probably true."

"With the people you deal with, too, if you'd admit it."

He was right. Sarah didn't like to think about it, but the father of the last baby she'd delivered had been murdered right in his own home. No one she'd met so far seemed completely innocent, either, except perhaps the baby himself.

"Did you find out anything else from the people at the funeral?" he asked.

"Just that all of Blackwell's female patients-"

"Clients," Malloy corrected her.

"Clients," she dutifully repeated, "were extremely fond of him. Apparently, his reputation as a ladies' man wasn't exaggerated."

"Do you think he actually seduced them?"

Sarah considered. "I believe there was some physical contact. Certainly, he had to touch his clients in order to perform his treatments, but there's different kinds of touching, if you catch my meaning."

"Wouldn't the women have objected if he took liberties with them?" Malloy asked with a frown.

Malloy was, Sarah remembered, something of a prude when it came to such things. "Not if they believed it was part of the treatment, and not if it felt very pleasant. And of course if they were under hypnosis ..."

Malloy made a face to express his distaste. "If they were in some sort of trance, he could've done anything he wanted. So you're telling me that all the husbands of these women could've had a good reason to blow Blackwell's brains out."

"I'm telling you that Blackwell gave these women relief from their pain, and he may have even given them pleasure. Many women never experience physical pleasure from their marital relations, Malloy. Blackwell must have seemed like a miracle worker to them."

Malloy was glancing around anxiously to make sure no one had overheard her. "Do you have to talk about things like that?" he asked.

"We're talking about the case," she reminded him. "I'm just trying to help you understand the kind of man Blackwell was, and who might have had a reason to kill him and why."

"I guess you're ruling out all his female patients, then," Malloy said sarcastically.

"Unless one of them was the jealous type," Sarah said with some amusement.

"Could one of them have been jealous of his wife?"

"Mrs. Fitzgerald apparently was, but if that was the motive, then Letitia would be dead instead of her husband. Although..."

"Although what?" he prodded when she hesitated.

"Mrs. Fitzgerald was not aware that Letitia was with child. If Blackwell led his patients to believe he had a marriage in name only..."

"That's a little hard to believe," Malloy said. "These women are married, too. Why would they expect him to be faithful to them?"

"You're right. That's pretty farfetched. On the other hand, if Letitia was jealous of them..."

"I haven't met Mrs. Blackwell yet," he reminded her, "but you said she doesn't seem like the type."

Sarah sighed. "I'm afraid she's not."

They walked a block in silence. Finally Sarah said, "Why don't you just arrest Amos Potter? Neither of us likes him much."

"I don't like Maurice Symington, either. Why couldn't he be the killer instead?" Malloy countered.

"I like that idea. Do you know that he spoke at Blackwell*s lectures when Letitia couldn't, and that the eulogy he gave today was the same speech he used for the lectures? He couldn't even be bothered to write a true eulogy for his son-in-law. But what would his motive be to kill Blackwell?"

"What would Potter's motive be?"

"Let's see, if either of them was upset about Edmund's bigamy, that would be a good reason to kill him. They're both devoted to Letitia and would be eager to protect her," Sarah said.

"Why should Potter care?"

"Because he's in love with Letitia."

"Then he wouldn't have to kill Blackwell. All he'd have to do was wait until her life was ruined by the scandal and be her sole remaining support. Then he could have her all to himself," Malloy pointed out.

"Only if she'd have him in return, and that doesn't seem likely. No, her father is a much more logical choice if Blackwell was killed because of his bigamy. Symington would want to save his daughter from the scandal and get revenge on Blackwell, too. Blackwell's death would ensure that the scandal never became public. He seems like the best suspect to me."

"Only if he knew about the Brown family, though," Malloy pointed out.

"You could ask him if he did," Sarah said.
