“Certainly,” I replied. “We consider that we have used sufficient precaution in having the bolt put upon the door. The result seems to justify our confidence. To be sure, until night before last we have had no important sums to deposit.”

“How about night before last?” Mr. Mudge asked.

“I had charge of the ticket money for the Home that we gained by the Catacomb Party,” I replied, “and I placed it in my division of the cabinet. There is just sixty dollars of it, and it is there now.”

“And was there during the night that Lawn Tennis slept in this apartment? And she knew it?”

“Yes, sir.”

“Then that is very good evidence that she was not the thief on the previous occasion.”

So confident was I in our security and in Polo’s honesty that I unlocked the cabinet to give Mr. Mudge convincing proof. What was our astonishment to find my compartment again empty. The floor of the cabinet was as clean as though swept by a brush. The sixty dollars which we held in trust for the Home were gone!
