A flight of stone stairs took them to the second floor.

"Rooms 11 to 20" was inscribed on the door and Steve pushed it open and led the way down to a very clean, well-lighted corridor to Number 12.

There could be no mistake about it, for the figures were very plainly printed on the white door.

Under the room number was a little metal frame which they afterwards discovered was for the purpose of holding a card bearing the names of the occupants.

Steve pushed the door open and, followed by Tom, entered.
There was still enough light from the one broad window to see by, but Steve found a switch near the doorway and turned on the electricity.
