A shaded light in an alcove at the head of the stairs threw a dim light down the passage which led off the first-floor landing, but Musard felt for the electric switch and pressed it.

The light flooded an empty corridor, with the door of the room nearest to him gaping into a dark interior.
Musard stepped inside the open door, struck a match to find the switch, and walked over and turned on the light.

As he did so, Phil and his father reached the door and followed him into the room, where, less than two hours before, Miss Heredith had been with Phil's young wife, and left her to sleep.

The room seemed as it had been then; there was no sign of any intruder.

The cut-glass and silver bottles stood on the small table by the head of the bed; the gold cigarette case was open alongside them; a novel, flung face downward on the pillows, revealed a garish cover and the bold lettering of the title--"What Shall it Profit ?"--as though the book had dropped from the hand of some one overcome by sleep.
