“Take him awa'!” came in a sudden frenzied shriek. “Take him awa'! He's there at your elbow, Kreener, mockin' me, and pointing to that damned violin.”

“Here!” said the stranger, a high note of command in his voice. “Drop that! Sit down at once.”

Even as the other obeyed him, the cloaked stranger, stepping to the mantelpiece, opened a small box which lay there beside the glass case. He turned to me; and I tried to shrink away from him. For I knew—I knew—yet I loathed to look upon—what was in the box. Muffled as though reaching me through fog, I heard the words:

“A perfect human body...in miniature... every organ intact by means of... process... rendered indestructible. Tcheriapin as he was in life may be seen by the curious ten thousand years hence. Incomplete... one respect... here in this box...”

The spell was broken by a horrifying shriek from the man whom my companion had addressed as Colquhoun, and whom I could only suppose to be the painter of the celebrated picture which rested upon the mantelshelf.

“Take him awa', Kreener! He is reaching for the violin!”

Animation returned to me, and I fell rather than ran down the darkened stair. How I opened the street door I know not, but even as I stepped out into the squalid alleys of Pennyfields the cloaked figure was beside me. A hand was laid upon my shoulder.

“Listen!” commanded a deep voice.

Clearly, with an eerie sweetness, an evil, hellish beauty indescribable, the wailing of a Stradivarius violin crept to my ears from the room above. Slowly—slowly the music began, and my soul rose up in revolt.

“Listen!” repeated the voice. “Listen! It is 'The Black Mass'!”
