Then he remembered Chapter IV on babies and other small humans. Since the night when he had separated the mannikin from its constituent parts, he’d been running through the manual as an intellectual exercise. He didn’t feel quite up to making some weird error on a small human. But twinning wasn’t supposed to be as difficult.

Only by Gog and by Magog, by Aesculapius the Physician and Kildare the Doctor, he would not disassemble this time. There must be other methods of disposal possible in a large city on a dark night. He’d think of something.

“I’d be glad to watch the baby for a few hours.” He started down the hall to anticipate her polite protest. “Don’t have a date tonight myself. No, don’t mention it, Mrs. Lipanti. Glad to do it.”

In the landlady’s apartment, her nervous sister briefed him doubtfully. “And that’s the only time she cries in a low, steady way so if you move fast there won’t be much damage done. Not much, anyway.”

He saw them to the door. “I’ll be fast enough,” he assured the mother. “Just so I get a hint.”

Mrs. Lipanti paused at the door. “Did I tell you about the man who was asking after you this afternoon?”

Again? “A sort of tall, old man in a long, black overcoat?”

“With the most frightening way of staring into your face and talking under his breath. Do you know him?”

“Not exactly. What did he want?”

“Well, he asked if there was a Sam Weaver living here who was a lawyer and had been spending most of his time in his room for the past week. I told him we had a Sam Weber—your first name is Sam?—who answered to that description, but that the last Weaver had moved out over a year ago. He just looked at me for a while and said, ‘Weaver, Weber—they might have made an error,’ and walked out without so much as a goodbye or excuse-me. Not what I call a polite gentleman.”
