"Nine months," was the reply.
"Had you saved any money while working in your other positions?"
"Well, the salary was small--I couldn't have saved much."
"How did you live those two years from the time you left the Hartford Bank until you accepted this position?"
The girl stammered a little.
"I received assistance from friends," she said, finally.
"Go on."
"That bank in Hartford," she continued, with a little gleam of resentment in her eyes, "had a safe similar to the one at the Ralston National, though not so large. It was blown in identically the same way as this one was blown."
"Oh, I see," said the scientist. "Some one was arrested for this, and you want to give me the name of that man?"
"Yes," said the girl. "A professional burglar, William Dineen, was arrested for that robbery and confessed. Later he escaped. After his arrest he boasted of his ability to blow any style of safe. He used an invention of his own for the borings to place the charges. I noticed that safe and I noticed this one. There is a striking similarity in the two."
