After eating her supper, Sarah was sitting by her front window, mentally composing a note to Malloy telling him she had some important information and needed to meet with him right away, when she saw him coming down the street.

Mrs. Ellsworth saw him, too, and he had to stop and make small talk with her for a few minutes. Ever since Mrs. Ellsworth had saved Sarah’s life, she had taken a great interest in hearing about the crimes Malloy was working on. Unfortunately, Malloy studiously avoided telling her about any of them, which Mrs. Ellsworth found extremely frustrating.

As soon as he could, Malloy extricated himself from her and made his way to Sarah’s door. She was waiting for him as he came up the steps. “Did she offer you some pie?” Sarah asked as he entered the house.

“No,” he said, removing his hat. “She’s probably going to bring it over later. She thinks I’m a saint for trying to solve your husband’s murder. Did you have to tell her that?” He was pretending to be annoyed.

“It was either that or let her think you’re courting me. Which would you prefer, Malloy?” she asked with some amusement.

He frowned as he pretended to consider his options. “If she thought I was courting you, she might not come over and bother us,” he pointed out.

“I wouldn’t count on it,” Sarah replied. “Come in and have some coffee before you get started. I’ve got something very interesting to tell you.”

He rolled his eyes, but he followed her into the kitchen and sat down obediently at the table.

“I found the redheaded lover,” she told him smugly when she’d poured his coffee.

He almost dropped the cup. “You what?”

“That’s what you told me to do,” she reminded him. “The only problem is that he’s the same fellow she eloped with before-Peter Dudley. They were running away together when her horse threw her, and she was injured.”

“He’s the schoolmaster, then?”

“That’s right. It appears that Mr. Symington didn’t have him killed, just discharged. I’m sure he figured Letitia would never encounter him again, so having him murdered was a needless expense.”

Malloy ignored her sarcasm. “How did she encounter him again?”

“He went to one of Blackwell’s lectures. He apparently saw Letitia’s name on the poster and wanted to see how she was. He must have felt terribly guilty because she’d been hurt, and then he hadn’t been able to find out if she’d ever recovered. He’d lost his position and come to the city, so he hadn’t had any contact with her at all until then, according to Letitia. He works in a bank or something now.”

“And he has red hair,” Malloy said, sipping his coffee thoughtfully.

“Extremely red hair. But even if he didn’st, Letitia admitted he was the baby’s father.”

“She just told you, right out?” Malloy marveled. “I know priests who can’t get confessions like that!”

Sarah tried to look modest. “I think she just needed to confide in someone. Someone who wouldn’t judge her, that is.”

“She deserves to be judged,” Malloy said flatly.

“Perhaps, but Blackwell wasn’t without guilt either. He only married her because she wanted to stop doing the lectures. He pretended to be in love with her, and he used his considerable charms to convince her he was. But as soon as they were safely married, he didn’t even bother to… uh… to share her bed.”

Malloy choked on his coffee. She should have waited until he wasn’t drinking to tell him that. She knew he didn’t like discussing such things, especially with her.

“Are you all right?” she asked as he coughed.

He nodded and kept coughing for a few more minutes. Finally, he was able to speak again. “She told you that, too?” he asked incredulously.

“As I said, she needed to unburden herself. The strangest part is that when Letitia turned up with child, Dr. Blackwell didn’t even realize he couldn’t be the father. That’s how little attention he paid to her. She must have been terribly lonely and unhappy.”

“I guess committing adultery made her feel better,” Malloy scoffed.

“I’m not excusing her, Malloy. I’m just explaining.”

“All right, then explain why she didn’t leave Blackwell for the schoolmaster after he found her again and they discovered they were still in love.”

“That’s easy. Divorce is extremely difficult and expensive. Letitia’s father was hardly likely to finance one for her, and she and Dudley had no means of their own to do so. Besides, if she did divorce Blackwell, he could keep her child.”

“Why would he want a baby that wasn’t his?” Malloy asked skeptically.

“He probably wouldn’st, but he could legally keep the child, and even the threat of that would be enough to prevent Letitia from leaving him. Then he could make her life even more miserable than it already was, and she wouldn’t dare complain. And Blackwell could force her to continue appearing at his lectures.”

Malloy needed no more than a moment to see the significance of this information. “But if Blackwell was dead, the lovers could be together with no other problems.”

“I believe you already pointed that out to me,” Sarah reminded him, “which is why you assigned me the task of finding the redheaded lover in the first place.”

“I didn’t really expect you to find one,” he admitted.

“I didn’t either,” she admitted right back. “But now that I have, you have another suspect in Blackwell’s death.”

“Do you think this Dudley could have done it?”

Sarah considered. “He’s certainly devoted to Letitia. And he wasn’t above bedding another man’s wife. Did I tell you they met at an opium den for their trysts?”

“Good God.”

“He also eloped with an innocent young girl against her family’s wishes. I think he’s extremely foolish, maybe even foolish enough to commit murder and try to make it look like suicide, especially if he thought it was the only way to protect Letitia.”

“A schoolmaster might be smart enough to think of the suicide thing, too. A good way to avoid suspicion. If there’s no murder, nobody will be looking for a killer, and he can come courting the widow afterward with no one the wiser.”

“Murder would solve another problem as well,” Sarah said. “Letitia was concerned about living on a bank employee’s salary until I reminded her she would inherit her husband’s estate. She wouldn’t have gotten anything at all if she divorced him.”

“She won’t get anything now, either,” Malloy said.

“What do you mean?”

“I mean Blackwell didn’t leave any estate.”

Sarah frowned. “I know he didn’t own the house, but surely he had something put aside.”

“Not a penny, according to Mr. Potter, who seemed pretty upset about it himself. Turns out he was supposed to be a partner in the business and get half of everything. He even thought he owned half of the house.”

“Oh, my,” Sarah said, giving herself a moment to absorb this. “If Dudley and Letitia didn’t know this, as they apparently didn’st, then it wouldn’t rule them out as suspects, but it also gives Potter another reason to murder Blackwell, besides being in love with Letitia. He thought he would inherit some money, too.”

“Money that he’d use to pay me a reward for finding the killer,” Malloy suggested mildly.

“Oh, yes, I keep forgetting about that. I guess I’m going to have to give up on making Mr. Potter the killer,” Sarah said.

“I understand the temptation,” Malloy said with a grin. “He’s a hard man to like, especially when he keeps insisting poor Calvin Brown killed his father.”

“That is tactless of him,” Sarah agreed. “Oh, wait, I just thought of something else. If Letitia’s marriage to Blackwell wasn’t valid, then she wouldn’t have needed a divorce to marry Dudley.”

“She wouldn’t have needed to kill her husband either, which would eliminate her and Dudley as suspects. Do you think she knew?”

“If she did, she’s done a remarkable job of hiding it.”
