His plan was to discover where Joe lay, wake him up, and force him, by threats of instant death as the penalty for non-compliance, to deliver up all the money he had in the restaurant.
Now, it happened that Joe and his guest slept in opposite corners of the room.

Rafferty discovered Joe, but was entirely ignorant of the presence of another person in the apartment.
Joe waked on being rudely shaken.
"Who is it ?" he muttered drowsily.
"Never mind who it is!" growled Jack in his ear.

"It's a man that'll kill you if you don't give up all the money you've got about you!" Joe was fully awake now, and realized the situation.

He felt thankful that he was not alone, and it instantly flashed upon him that Watson had a revolver.

But Watson was asleep.
