e doorway into the inner room which he had seen Mrs.
Irvin enter. The air was laden with the smell of frankincense.

"A lantern!" he called. "I left one on the divan."

But Monte Irvin had caught it up and was already at his elbow. His hand
was shaking so that the light danced wildly now upon the carpet, now
upon the green walls. This room also was deserted. A black gap in the
curtain showed where the material had been roughly torn. Suddenly:

"My God, look!" muttered the Inspector, who, with the others, now stood
in the curious draped apartment.

A thin stream of blood was trickling out from beneath the torn hangings!

Monte Irvin staggered and fell back against the Inspector, clutching at
him for support. But Sergeant Burton, who carried the second lantern,
crossed the room and wrenched the green draperies bodily from their
fastenings.

They had masked a wooden partition or stout screen, having an aperture
in the centre which could be closed by means of another of the sliding
doors. A space some five feet deep was thus walled off from this second
room. It contained a massive ebony chair. Behind the chair, and dividing
the second room into yet a third section, extended another wooden
partition in one end of which was an ordinary office door; and
immediately at the back of the chair appeared a little opening or

And now the narrow apartment became filled with all the awe-stricken
company, only excepting Monte Irvin, and Brisley, who was attending to
the swooning man.

Flat upon the floor, between the door and the ebony chair, arms extended
and eyes staring upward at the ceiling, lay Sir Lucien Pyne, his white
shirt front redly dyed. In the hush which had fallen, the footsteps
of Inspector Whiteleaf sounded loudly as he opened the final door, and
swept the interior of an inner room with the rays of the lantern.

The room was barely furnished as an office. There was another
half-glazed door opening on to a narrow corridor. This door was locked.

"Pyne!" whispered Gray, pale now to the lips. "Do you understand, Seton?
It's Pyne! Look! He has been sta
