Clancy threw off his frock coat, folded it carefully and laid it on an office stool.
On top of his coat he placed his silk hat.
Meanwhile, Spark had produced the “tools”—and peculiar tools they were.
They consisted of a rubber bag, a bar of brown soap, a coil of fuse and some caps.
Each man knew just what work he was to perform, and went about it without a word.
Breaking the bar of soap in two, Clancy handed one piece to Spark, and they set to work plastering up the crack at the edge of the vault door.
This was skillfully and quickly accomplished.
From the top of another office stool, Clancy fashioned a cup of the soap on the upper crack.
The bag contained nitroglycerin.
