Meanwhile, Billy Kelly had taken his place just inside the back door with a pistol and a lead pipe and seated himself on the back stairs, while George Mason was sauntering about outside the door to give warning and prevent interruption from that point.
All these men covered the operations of Jimmy Hope and Johnny Dobbs, who opened the vault door with Werkle's key and combination, and fell to work on the steel safes within. There were three, one on either side and one in the back. With the sledge hammer and knife-edged wedges the two burglars spread the crack of one of the safe doors wide enough to force in the necessary explosive. Pausing only long enough to learn from his confederates that the coast was clear, Hope touched it off. A muffled reverberation reached the policeman across the street. He glanced over at the bank.
"Banjo Pete" dropped his duster, crossed to the window, and peered out as if the explosion were from outdoors somewhere, and he were mildly wondering. The policeman resumed his reflections and the work went on. Fifteen minutes later another muffled boom marked the blowing of the second safe.
At this point Hope and Dobbs paused to collect the booty. It was more than they could carry, so half a peck of bonds was passed out to the vigilant Billy Kelly on the back stairs, as much more to the silent Goodey, unwelcome watcher by the bedside of the feeble old woman.
With bulging eyes, Mr. and Mrs. Werkle saw a few bags of gold tossed in to their guardians and pocketed. The gang had been growing richer at the rate of about a hundred thousand dollars a minute for some time.
As Hope and Dobbs returned to attack the third safe, which stood in the rear, there came a threatened interruption. George Mason, outside, gave the signal to Billy Kelly, inside the back door, to be on guard. A milk wagon stopped, the driver descended with a quart of milk, opened the back door, and was about to ascend the stairs with it to deliver to the janitor.
Billy Kelly, on guard on the stairs for just such an emergency, politely informed him that the janitor and his family had gone away and would need no more milk for some time. The milkman replaced the bottle in his wagon and went on, while Hope drove home his wedges.
But now came a serious interruption, the wily old Coakley signaled that the end of their operations had come. It was inevitable that Kohlman, the barber, would soon open up his little shop beneath the bank. This was what Coakley signaled to "Banjo Pete," who called the news to the workers within the vault.
Immediately Hope, Dobbs, and Lyons laid down their tools, put on their coats, stuffed the remainder of the undisturbed plunder inside their clothes, and told the band to quit.
