“I’ll go down and see,” replied Barker. “If anybody comes up here and tries to nose around bluff him off.”
“We will,” said Casco. “But keep watch, and give us plenty of warning.”
This was agreed to, and Barker left the garret immediately.
The others grew silent, Casco standing by the stairs with ears on the alert.
Five minutes passed. They dragged slowly to Bob, who was wondering what would happen next, and if he would ever get out of his predicament with a whole skin.
Suddenly two pistol-shots rang out. They were followed by a whistle outside, and then another on the second floor below. The raid by the police had begun.
As it was dark in the garret, Bob could not make out the movements of his captors.
He heard Casco say something to Grogan, and then the two went off, leaving old Blake in sole charge. The latter remained near the stairs, listening intently for the first sign of any one trying to come up.
Presently there was another cry, and then Blake hurried to Bob’s side.
“Listen to me,” he said. “Don’t you dare to make a move or a sound till I come back. If you do, I’ll fix you.”
