The young man cast a suspicious glance at the elder, threw a nickel on the bar and hurried out.
Old Spicer also threw down a piece of money and started for the door.
"It must be done now," he thought; "but it will be a tough job taking him alone."
At that instant he caught sight of two men coming up the street.
They were Detectives Frank Mangin and James Maguire.
Old Spicer immediately gave them a signal, and hurrying forward, they came up in front of the young man. Old Spicer still remaining behind him.
"Chamberlain," said Mangin, in a determined tone of voice, "you are our prisoner."
The street was crowded with people. Chamberlain, who was a muscular young fellow nearly six feet tall, uttered a fearful oath, sprung forward, threw the detective to one side, and drew a revolver.
The crowd instantly scattered.
But the detectives grappled with him, and Old Spicer coming up quickly, knocked the pistol out of his hand, while Maguire, striking him a blow in the side of the head, sent him headlong on the pavement.
