Through this the two burglars passed, entering the cellar beneath the store.

Shadow supposed that after depositing their loads both would return to the bank building. In this he was mistaken, for while one returned the other remained for the purpose of receiving the loads which now began to arrive.

The detective was in a box.

To attempt to retreat now was equivalent to detection: to remain, he would be spotted the very minute a light was brought into the cellar. While it was dark, and he even suppressed his breath, he was safe, but for no greater length of time.

Shadow at last determined on making an attempt to reach the stairs and mount them, so as to give us the word.

Holding his breath, he took a step, and then paused.

In a minute he took one more step and paused again.

He had not been heard.

Still another step.

And yet he was undetected.
