“Mr. Smith sent me a registered letter. He told me that our instructions were to find Mrs. Lintig, not to bother about Dr. Lintig, that he was very much put out at our failure to follow instructions, and that we weren’t to proceed any farther with the case.”

After a while, when I said nothing, she said, “Hello, Donald. Are you there?”

“Yes,” I said. “I’m thinking.”

That got action with Bertha. She said, “Well, for Pete’s sake, don’t think over the long-distance telephone.”

“I’ll see you some time tomorrow,” I said, and hung up, while she was still trying to talk.

I sat and thought for the space of a couple of cigarettes, then I picked up the telephone and said, “Connect me with Mrs. Lintig’s room, will you please?”

The clerk said, “I’m very sorry, Mr. Lam, but she’s checked out. She received a telegram and said she had to leave at once.”

“Did she leave any forwarding address?”

“No.”

“How did she leave, on the train?”
