"Oh, I'll look out for it," assured Merry. "No one will think of molesting me to-night."
He little knew that these words were overheard by his worst enemy. From his own unlighted room Sport Harris peered forth, having the door slightly ajar.
"So he's taking the money to his room?" thought the young scoundrel. "Well, he must have a pretty good pile of it, for that was a great house. I'm rather hard up, and I wouldn't mind lifting a fat roll off that fellow."
In his stocking feet he slipped out into the hall and followed Frank, locating Merry's room.
Frank went in, closed the door and locked it.
He was pretty tired, and he lost little time in undressing. He did not give Sport Harris a single thought. In a short time he was in bed and the light was extinguished.
Tired though he was, it was some time before Frank could get to sleep, for his brain was teeming with exciting thoughts.
At last, however, he dropped off.
Frank awoke with a consciousness of danger. It seemed that a slight rustling had aroused him. In a twinkling he was on the alert, although he kept perfectly still.
There was a sliding sound near the door. Turning his eyes, he saw a dark figure slowly slipping in through the transom, which was wide open.
