“Jack, where were the papers put?”
“In a drawer inside the safe, doctor.”
The boy had swung the door of the safe open, and the next instant he turned a white, startled face on the others.
“The drawer is empty. It has been robbed!” he exclaimed excitedly.
“Keep cool, my boy,” admonished the doctor. “You are sure the safe was closed when you left?”
“I shut it myself, doctor. There is not a chance that I could be mistaken.”
“And the combination?”
“I gave it to my father with my own hands. It was the last thing I did before I left.”
“Then the safe could only have been forced open unless some one possessing the combination opened it.”
“That is the only way any one could have gained access to its contents.”
