Then it was that the detective saw Ralston come up, and, while apparently watching the window also, thrust his hand into the pocket of the office boy and withdraw the package of money, which he at once slipped into his own pocket.
Mr. Sharpleigh smiled a little to himself.
“Very neat!” he soliloquized, “but it won’t go down, my cunning friend.”
Felix gave a little side glance, seeing what was going on, but immediately stared again in at the window.
Sharpleigh beckoned to a tall man, dressed as a civilian, but really an officer in plain clothes.
“Go after him!” he said, in a low voice, indicating Ralston.
Then he followed Felix, who in about five minutes began to show signs of agitation.
He thrust his hand wildly into his pocket, and looked panic-stricken.
“What is the matter, my boy?” asked Sharpleigh, blandly.
“Oh, sir, I have been robbed,” faltered Felix.
