“There was some people in the park, it seems like, and maybe somebody walking on the sidewalk.”

“I mean anyone who looked like they were sneaking around or hurrying away from the house?”

Calvin considered. “I don’t think so. Why…? Oh, you mean the killer,” he guessed after a moment. “No, I didn’t see nobody like that. I wish I did. I’d sure like to help. The fellow Mr. Potter, he thinks I killed my father, so I want to help all I can to find the real killer.”

“I know you do, Calvin,” Malloy said wearily. He was more convinced than ever of the boy’s innocence. And now he had another good suspect. Symington must have been furious when he found out the truth about his son-in-law. Could he have figured out a way to free his daughter from the scandal of Blackwell’s secret family? The crime indicated that someone had carefully planned it, even down to establishing Calvin as a suspect if the suicide ruse failed. His daughter would be a respectable widow instead of a bigamist’s wife.

But if Frank wanted to accuse a man like Symington of murder, he’d need a lot more than a suspicion.

“Does any of this help, Mr. Malloy?” the boy asked eagerly.

“Not enough,” Frank replied with a sigh.

SARAH WASN’T SURE how often she could visit the Blackwell home before someone began to wonder what she was doing there. Sunday afternoon she once again arrived to check on Mrs. Blackwell’s condition. Since no one in the house had any idea how often Mrs. Blackwell needed to be checked, she supposed the ploy would work for a while yet.

Mrs. Blackwell was sleeping when she arrived, so Sarah went to see how the baby was doing. He was being fed when the nurse bade her enter.

“Oh, Mrs. Brandt, I’m so glad to see you. Sit down and rest yourself,” the nurse said from where she sat in the rocking chair. “I’ll have some tea brought up. Would you pull the bell there? Someone will come.”

The woman was so obviously desperate for company that Sarah couldn’t refuse. She took a seat in a comfortable chair that had been provided for the nurse’s use when she wasn’t rocking the baby. She was glad to see the baby seemed to be suckling just fine and gaining some weight.

“He looks well,” Sarah said.

“Oh, he’s all right, I guess. Still sleeps a lot, but that’s to be expected, I suppose. And sometimes I’ve got to tickle his feet to keep him awake while he nurses, but there’s lots of babies what do that.”

“Yes, there are,” Sarah agreed.

“I was hoping you’d come,” the nurse said after a moment. “I found out some things I thought you’d want to know.”

“What kind of things?” Sarah asked politely.

“For instance, do you know how Mrs. Blackwell started using the morphine in the first place?”

“It’s my understanding that she was injured very badly in a riding accident,” Sarah said. “She started taking it for the pain.”

“I suppose that’s true as far as it goes,” the nurse said, her homely face creasing into smugness. “But do you have any idea where she was riding off to, and with who, when she had that accident?”

Sarah hadn’t given the matter any thought, but she was willing to play along. “No, I don’t.”

“Then you’ll be surprised to hear that she was eloping.”

Sarah’s first thought was that she had been eloping with Dr. Blackwell, but that wasn’t possible. She hadn’t even known him then. “Who was she eloping with?” she asked.

“That’s the scandal, don’t you know,” the nurse told her with satisfaction. “She was running off with the local schoolmaster!”

“Good heavens!”

“I got this from her maid what’s been with her since she was in pigtails,” the nurse informed her. “She said Mrs. Blackwell had been carrying on with this fellow behind her father’s back. The father never would’ve approved of a marriage between them, so the two of them were running away together. Except that Mrs. Blackwell’s horse stumbled in a ditch, and she was throwed.”

“How awful,” Sarah said, her mind trying to grasp this information and analyze its importance. She was sure Malloy would figure it out instantly, but for once she wanted to beat him to it.

“It was more than awful. Seems like it was night and her young man didn’t want to leave her there and go for help, so he had to carry her back to her father’s house. I guess there was quite a ruckus when he brought her in, with everybody thinking she was tucked up safe in her bed and all.”

Sarah could well imagine how Mr. Symington would have greeted the man responsible for what he would consider abducting his daughter and causing a terrible accident. “What happened to the schoolmaster?”

“Oh, he was let go, as you can guess. Don’t nobody know what become of him after that. And Mrs. Blackwell, she was confined to her bed for months and months. Her maid said sometimes she’d scream with the pain, and the only thing that’d help was the morphine. Poor thing, so young and pretty and not able to get up from her bed for all that time.”

“It was quite fortunate that her father found Dr. Blackwell when he did,” Sarah said, knowing she shouldn’t encourage servants to gossip about their employers, but knowing the information could be important. One never knew which scrap of information might lead one to the killer. She was going to see Malloy tomorrow, and she’d love to have something interesting to report.

A maid’s knock interrupted them, and the nurse instructed her to bring some tea for Sarah. When she had gone, Sarah said, “This makes it even more romantic that Dr. Blackwell and his wife fell in love after he treated her.”

“Oh, it would, if that’s what happened,” the nurse confided. The baby was now fast asleep at her breast, but she hardly seemed aware of him.

“What did happen, then?” she asked, as the nurse was waiting for her to do.

The nurse looked around, as if she expected to find someone eavesdropping, but they were, of course, alone in the room except for the sleeping baby. “According to Daisy, Mrs. Blackwell’s maid what’s been with her since she was a girl, Dr. Blackwell somehow convinced her father to make her stand up at his lectures and tell how Dr. Blackwell cured her. She didn’t want to do it, and who could blame her?”

Sarah nodded encouragingly, even though she already knew all of this.

“She did it for a while, but she wanted to stop. Her maid said she had to take morphine just to get her through it, but she didn’t dare let her father or Dr. Blackwell know. They thought she’d stopped taking it after she got well. It seemed like the father was going to tell Dr. Blackwell his daughter was finished testifying for him, but then Dr. Blackwell, he starts paying court to the girl.”

“Was her father pleased?” Sarah could hardly credit it.

“What do you think? The girl was damaged goods. If anybody found out she’d been carrying on with a schoolteacher and tried to elope with him, she would’ve been ruined.”

She was right, of course. If Letitia was no longer a virgin, or even if there was reason to believe she wasn’st, then no respectable man of her own class would have her, particularly if she’d been having an affair with a penniless schoolteacher.

“Do you think she didn’t love Dr. Blackwell?” Sarah asked.

“Oh, my, who can say? With a man like that… Well, you know what I mean.”

“No, I don’st,” Sarah said. “I never met Dr. Blackwell.”

The nurse nodded knowingly. “Then you couldn’t know. I only met him once, but I can see how he’d turn a girl’s head,” the nurse eagerly explained. “Right handsome he was, tall and dark, and dressed real smart in his fine clothes. Good manners, too, and well-spoken. Had a way of looking right at you, like he knew what was going on inside your head. Made my heart flutter a bit, I don’t mind saying, even though I knowed he wasn’t interested in me that way.”

Sarah could hardly comprehend it. A man who took the time to charm the woman who was going to be his child’s wet nurse. He must have been a master at beguiling women. Poor, tortured Letitia hadn’t stood a chance.
