Bristol returned the letter to me without a word, and turning to Lester, who had reentered carrying a heavy pick-axe, he attacked the oblong box with savage energy.

Through the house of death the sound of the blows echoed and rang with a sort of sacrilegious mockery. The box fell to pieces.

"My God! look, sir!"

Lester was the trembling speaker.

The box, I have said, was but three feet long by one foot square, and had clearly defied poor Deeping's efforts to open it. But a crescent-shaped knife, wet with blood, lay within!

THE OCCUPANT OF THE BOX

Dimly to my ears came the ceaseless murmur of London. The night now was far advanced, and not a sound disturbed the silence of the court below my windows.

Professor Deeping's "Assyrian Mythology" lay open before me, beside it my notebook. A coal dropped from the fire, and I half started up out of my chair. My nerves were all awry, and I had more than my horrible memories of the murdered man to thank for it. Let me explain what I mean.

When, after assisting, or endeavouring to assist, Bristol at his elaborate inquiries, I had at last returned to my chambers, I had become the victim of a singular delusion — though one common enough in the case of persons whose nerves are overwrought. I had thought myself followed.
