“Everything all right there?”
“Yes.”
“It’s O. K. here. I wonder what it was we heard?”
As he spoke, Geary placed his hand on the fastening of the door and opened it.
“It wasn’t fastened on this side,” he said, stepping through.
“It was on this side, though,” replied Gilmore, “so everything must be all right, after all.”
“Did you look in the space around the vault?”
“Yes; don’t you remember going in there with me?”
“Of course. Then the noise we heard must have been out on the street, or in some adjoining cellar.”
“I suppose so,” replied Gilmore.
