had spoken to Biggin at length in the motorcar. “The search has been expanded to include the river—”

She cried out at that, but he said, “Mrs. Teller, we must be realistic. Your husband has been under some stress. He may have left the clinic with the intent to do himself a harm, and if we’re to find him in time we must try to understand his state of mind.”

“No,” she said forcefully. “Walter wouldn’t kill himself. I know my husband, he has no reason to want to die and every reason to want to live. I won’t listen to this.”

He spent another ten minutes trying to make a dent in her certainty.

Finally he asked, “If we knew what had caused your husband’s extraordinary illness, we might be better able to judge where he has gone and why. What happened to him between the bank and your house that changed him and brought on his paralysis?”

“Don’t you think I’d have told Dr. Fielding—or the doctors here—if I had any idea at all?” She was angry with him. “My sister was here earlier this morning. I asked her if she knew anything that would help. Sometimes Walter talked to her about his mission work. Mary has always strongly supported missions, and she has no illusions about the hardships people in the field endure. She couldn’t think of any reason either. And I could see that she was as worried as I was. So I didn’t have the heart to ask her what I really wanted to know. I wondered if someone could have cursed Walter out there. I’ve heard about such things. I mean, I don’t really believe in them, and I’m sure Walter doesn’t either. Still, you never know—”

Her voice broke and she put her hands over her eyes, partly ashamed of her fears and partly afraid to speak them aloud, to give them a reality.

Rutledge had nothing to say in response. It had hardly been twenty-four hours since her husband left, but irrational fears were already supplying answers to questions that had none.

He summoned a nursing sister to come and sit with her, then left.

Chapter 9

Rutledge found the London addresses for Edwin and Peter Teller, and drove to each house, but he was informed by the maids who answered the door that the family was away.

Wherever they were searching, he had a feeling that they were having no better luck than he had had in finding their brother.

The second day of Walter Teller’s disappearance brought no new information. It was as if he’d never existed.

Hamish said, “If he were wandering about—truly lost—someone would ha’ noticed him and brought him to a hospital or the police.”

It was what had been on Rutledge’s mind all morning.

“He might not wish to be found,” he replied. “An alternative to suicide.”

“There’s that, aye,” Hamish agreed.

It made a certain kind of sense. If one can’t face the nightmare, one can try to avoid it. But what sort of nightmare haunted a man like Teller?

He went back to question Teller’s doctors.

They had failed to unlock their patient’s secrets.

He said, “Teller’s wife has been casting about for answers as well. She has even considered a curse on her husband, from his time in places like West Africa.”

“Curses are interesting things,” Dr. Davies replied. “They work when people believe that they will work. In short, the curse is effective because the victim accepts that it will happen, and that nothing can be done to prevent it from happening as foretold. In my view, Teller was far too intelligent—and knowledgeable about the people with whom he worked—to be taken in by such a threat. I’ve talked to several other missionaries who told me that a curse had been put on them by a tribal shaman, a way of discouraging competition, one might say. And of course it failed, which caused no end of trouble for the shaman. His power was seen to be weak.”

“What would be a modern equivalent of a curse?” Rutledge asked.

“Ah,” Davies answered him. “That’s an even more interesting question. I expect it would take the form of something happening once and the fear that it could happen again. If one finds an intruder in one’s house on a dark night, it might well be something one would fear, coming into that same house on another dark night.” He smiled. “Guilt can produce irrational fears as well.”

“Was Teller likely to die of his illness? Was that on his mind?”

“At a guess, no, it wouldn’t have killed him.
