"You seriously suggest that the man was not Professor Bulge—that he was an impostor?"

"The conclusion is inevitable. Where were you on Monday, Professor?"

"I was on a short lecturing tour in the Midlands. On Saturday I was in Nottingham. On Monday in Birmingham. I did not return to London until yesterday."

Carrados turned to the manager again and indicated Draycott, who so far had remained in the background.

"And this gentleman? Did he by any chance come here on Monday?"

"He did not, Mr. Carrados. But I gave him access to his safe on
Tuesday afternoon and again yesterday."

Draycott shook his head sadly.

"Yesterday I found it empty," he said. "And all Tuesday afternoon I was at Brighton, trying to see a gentleman on business."

The manager sat down very suddenly.

"Good God, another!" he exclaimed faintly.
