Guerchard and Dieusy dashed at the doors of the opening of the lift-well, pulling and wrenching at them.
Suddenly there was a click; and they heard the grunting of the machinery.

There was a little bump and a jerk, the doors flew open of themselves; and there was the lift, empty, ready for them.

They jumped into it; Guerchard's quick eye caught the button, and he pressed it.
The doors banged to, and, to his horror, the lift shot upwards about eight feet, and stuck between the floors.
As the lift stuck, a second compartment, exactly like the one Guerchard and Dieusy were in, came up to the level of the floor of the smoking-room; the doors opened, and there was Lupin.

But again how changed! The clothes of the Duke of Charmerace littered the floor; the kit-bag was open; and he was wearing the very clothes of Chief-Inspector Guerchard, his seedy top-hat, his cloak.

He wore also Guerchard's sparse, lank, black hair, his little, bristling, black moustache.
