“Well, one thing is for certain, with your husband gone, you won’t have to attend those lectures anymore. So if you’d like to try stopping the morphine again, I can help you when you’re stronger,” Sarah offered.

“I can’t think about that now,” she said wearily. “I can’t think about anything now. I just want to sleep.”

“That’s certainly a good idea. I’ll make sure no one bothers you.”

“Especially my father,” Mrs. Blackwell said when Sarah started to leave. “He came yesterday, and he made me cry, talking about Edmund. I don’t want to cry anymore. Please tell him I’m not able to see him.”

“Of course,” Sarah agreed, wondering how she would explain this to Mrs. Blackwell’s father. She left to check on the baby.

MALLOY WAITED IN the parlor for Sarah Brandt. She didn’t even say hello when she came in.

“So, Malloy, when do you plan to arrest the killer?” she asked instead, trying to nettle him.

He didn’t let on that she had succeeded. She was the only woman he knew who could look appealing while being infuriating. “I need to ask Mrs. Blackwell some questions. When can I see her?”

“My guess would be a few weeks,” she told him without a hint that she was teasing him. “She asked me a few moments ago to tell her own father she was too ill to receive him, so she’s certainly too ill to see you.”

“Is she?”

“If she says she is, then she is,” she informed him. “Would you dare impose yourself on a woman during her lying-in?”

Frank tried not to feel the irritation he was feeling, mostly because it wasn’t entirely unpleasant. He actually enjoyed arguing with Sarah Brandt, as difficult as that was to understand. “I need to find out what she knows about her husband’s death, and the sooner I do that, the better chance I have of finding the killer.”

“I would be happy to question her for you if you’ll just tell me what you need to know,” she said, taking a seat on the sofa and making herself comfortable.

“You are not a member of the police force, and you are not involved in this investigation,” he reminded her.

“Well, then, I suppose you won’t be interested in the fact that Mrs. Blackwell uses morphine.”

“What?” Although he hadn’t intended to, he sat down in the chair opposite her.

“Mrs. Blackwell has used morphine for several years, except for a brief period,” she said. “It seems she began using it when she was injured in a riding accident.”

“That’s the accident her husband cured her of, isn’t it?”

“Yes, it is.”

“What was wrong with her exactly?”

“She said her back and neck were injured.”

Frank frowned. “He cured her of a broken neck?”

“I doubt it. More likely, she sprained her back or pulled something. Such injuries can be extremely painful, and there is no effective treatment except bed rest and opiates for the pain. Sometimes they get better, and sometimes they don’t.”

“Except Blackwell knew of a treatment for it,” Frank reminded her.

“So it appears. From what his wife told me, I think Blackwell must have been a bonesetter.”

“A bone-setter? You mean he set broken bones?”

“Not exactly. I suppose in the old days, that’s what bonesetters did, back before the science of medicine was so advanced and doctors began setting bones themselves,” she said, and Frank managed not to snort in derision. His opinion of medicine wasn’t quite as high as hers. “Nowadays,” she continued, “bonesetters perform manipulations on bones that make people feel better.”

“What do you mean ‘manipulations’?”

“I mean they move the body around and somehow manage to make bones shift position, on the theory that they are somehow out of their proper position, which is what is causing the problems. I imagine that something in Mrs. Blackwell’s spine or neck was somehow out of line from the accident, and Blackwell managed to realign it, thus relieving her pain.”

“Is that possible?”

“Apparently. She said her pain was completely gone within a few weeks, after she’d been confined to her bed for almost a year.”

“How did you find out she uses morphine?” Frank asked.

“Her baby became ill because he was no longer receiving the drug from his mother. I recognized the symptoms.”

“You mean to tell me the woman gave her baby morphine?” Frank was horrified.

“Not directly,” she explained patiently. “He would have gotten the effects of the morphine through the umbilical cord before he was born. Once he was born, he would no longer receive it. Sometimes, the baby receives enough of the drug through his mother’s milk to satisfy the craving, but Mrs. Blackwell chose to use a wet nurse, so after about a day, he was desperate for the drug and showing all the signs of deprivation. He would have died without it, so I gave him a small dose of opium to ease his suffering.”

“You let him have morphine?” Frank asked, horrified all over again.

She sighed with long-suffering. She always found Frank unreasonable, although he could never understand why. “My choice was to either give him the drug or watch him die in agony. What would you have done?”

Frank chose not to reply to that. “All right, so Mrs. Blackwell uses morphine. That’s unusual for a woman of her social class, but-”

“It’s not as unusual as you might suppose,” she disagreed. “Many women of her social class use opiates of some sort.”

“What on earth for?” He could understand why the poor used stimulants like alcohol and opiates to help them forget the grim realities of their existence, but what could a woman like Mrs. Blackwell need to forget?

“There are all kinds of pain, Malloy. Life can be hard even if you’re rich.”

He didn’t bother arguing with her. It was usually a waste of time, even when he knew she was wrong. “All right, so she uses morphine. What does that have to do with her husband’s death?”

“Her husband didn’t know she was still using it. He knew she’d given it up after he cured her, even though it was very difficult for her. Have you ever seen anyone going through the process of weaning himself off an opiate? Few people ever manage to do it. But then he forced her to speak at his lectures. He gave lectures to promote-”

“I know all about his lectures,” Frank said. “His assistant explained it to me, but he said Mrs. Blackwell was only too pleased to give her testimony of what the good doctor had done for her.”

“Mrs. Blackwell tells a different story. She hated speaking in public. It terrified her, but her father and Blackwell forced her to do it.”

“How could they force her if she didn’t want to do it?”

“Really, Malloy, how do you force people to tell you things they don’t want to tell you?” she asked, that gleam in her eyes that made her look so wicked he thought he should probably lock her away before she could cause any more trouble.

“Are you telling me they gave her the third degree?” he asked, giving her trouble right back.

“Of course not. You should know there are more effective ways of managing someone like Mrs. Blackwell. Women of her class are taught from birth to be obedient and compliant and to please men.”

“You’re from her class,” he pointed out, reminding her that she had been born into one of the oldest and wealthiest families in the city. “What happened to you?”

She gave him one of her looks, but she didn’t dignify his words with a reply. “The important thing for you to know is that Mrs. Blackwell started using morphine again to help overcome her fear of appearing at those lectures. It was the only way she could do it. Her husband didn’t approve of her using morphine, and she must have lived in constant fear that he would discover her secret. She also hated speaking at his lectures, which was why she needed the morphine in the first place. I imagine she was excused from doing them once her condition became apparent, but surely, he would have expected her to resume her appearances once the child was born. In fact, she told me he’d forbidden her to nurse the child herself because she had to be free to attend those lectures.”
