"What first put you on to the fact that I was after you?"
"Oh, you want to know too much," was the laughing reply. "Answer me a question."
"Go ahead."
"What first made you suspect the Eureka Association?"
"Mr. Gyde left his heir a statement of their dealings with him."
"Hm! I never thought of that possibility."
"Now answer my question."
"You'd like to keep me here, wouldn't you, until you have time to trace this call back, and send a man to nab me. Sorry I can't oblige. I'm at Grand Central and my train is leaving. Good-bye!"
The detective had not sufficient time, of course, to get his man. Oddly enough the humorous "Mr. B" had told the truth as to where he was. The call had come from the Grand Central station.
