“I have a plan,” said Harry.

“What?” asked the old detective, eagerly.

“Well, it may seem simple, but I think it will work. Go to an uptown hotel and register.”

“Well?”

“We will assume to go to our room. But in reality we will slip out by a rear entrance. Once the gang enters the hotel we will nab them.”

“But will they do that?”

“I think they will. Certainly they will leave nothing undone to encompass our death.”

“Very good!” agreed Old King Brady. “We’ll try your plan.”
