"Mr. Vanderpoel," the man told me.
"He was quite alone, I suppose?" I asked.
"Absolutely," the man answered. "He had a few callers at different times, but he spent most of his time in his rooms. If you are particularly anxious to discover his whereabouts," the clerk continued, "the night porter who would have started him off is still on duty."
"I should like very much to speak to him," I said.
The clerk touched a bell, and the porter came in from outside.
"You remember Mr. Vanderpoel leaving this evening?" the clerk asked.
"Certainly, sir," the man answered. "He went at about eleven o'clock."
"Did he go in a cab?" the clerk asked.
"In a four-wheeler, sir," the porter answered.
"Do you remember what address he gave?"
