CHAPTER III.
A DISCOVERY AND WHAT FOLLOWED "Hullo, what does this mean?
Here is a key in the door." It was Dick Rover who spoke.

He stood in the hallway of the hotel, and beside him were Tom and Sam.

They had eaten rather heartily at the restaurant and taken more time than they had anticipated.
"I didn't leave the key there," came from Tom.

"Here it is," and he brought it out of his pocket.

"I meant to leave it at the desk, but it slipped my mind." Dick found the door open and walked into the room, followed by his brothers.
