"Yes, and I have an idea."
"Good! Get it off your mind before you lose it. What's the idea?"
"I'm going to sleep in the upper berth."
"The upper berth?" wondered Hickey.
"Yes."
"I don't see any upper berth."
"Then watch me."
Dan proceeded to remove his coat and vest, collar and tie. Next he took off his shoes, Hickey in the meantime watching his companion with suspicious eyes.
Along either end of the compartment, over their heads, was a luggage rack extending the entire length, or rather, width, of the compartment.
Dan grasped the rack, pulled himself up to it and lay down as snug as if he were in reality in the upper berth of a sleeping car.
