THE DROP GAME Fairfax had an object in remaining behind.

He wanted to see if there was any way for him to get into Andy's room during the night, that he might rob him in his sleep.

To his great satisfaction, he found that there was a door between the two rooms, for the accommodation of persons in the same party, who wished to be in adjoining apartments.
It was, however, locked, but Fairfax was not unprepared for such an emergency.

He took a bunch of keys from his pocket, and tried them, one after another, in the lock.

There was one that would very nearly fit.
