“Can it be possible,” he asked, “that one of those fellows got down there during the fight?”

“It is possible,” replied Geary. “Get a candle and we’ll go down and look the place over.”

In the cellar everything looked as usual.

There was the double partition which had been built to shut the noise of the motor and the drill from the street, there were tools, pipes and iron bands lying around, and there, just beyond the broken cellar wall, was the heavy granite foundation of the bank vault.

The two men searched through every inch of the place, and then turned to the double wall.

“There is a door through here somewhere,” said Gilmore.

“Yes,” was the reply, “but it fastens from the other side as well as this, and we can never get through without breaking it down.”

“Well, if we can’t get through no one else can, that is one sure thing,” replied Gilmore. “It must have been the rats we heard.”

“Help! Help!”

The men were about to ascend the stairs to the room above when the cry reached their ears.
