"It is a place called Bishopsholme," he said gruffly, "on Putney Heath. Now let me pass."

"Wait, wait!" said the figure eagerly, "wait for me—only five minutes! I won't keep you! But don't go, there's death there, Solomon White! It is waiting for you—don't you feel it in your bones?"

The voice sank to a whisper, and in spite of himself, a cold shiver passed down White's spine. He half-turned to go back.

"Wait!" said the figure again eagerly, fiercely. "I shall not keep you a minute—a second!"

Solomon White stood irresolutely, and the mask seemed to melt into the darkness. White strained his ears to catch the soft patter of its shoes as it mounted the stairs, but no sound came. Then with a start he seemed to awake as if from a bad dream, and without another word strode down the remaining stairs into the night.

On the landing above, the strange being who called himself "Jack o' Judgment" stood outside the door of Boundary's flat. He had taken a key from his pocket and had it poised, when he heard the clatter of the other's feet. He stood undecidedly, but only for a second, then the key slipped into the lock and the door opened. The butler from his little pantry saw the figure and slammed his own door, bolting it with trembling fingers.

In a second Jack o' Judgment was in the room facing the paralysed trio.

He spoke no word, but suddenly his right arm was raised, some shining object flew from his hand, and there was a crash of glass and instantly a vile odour. On the opposite wall where the bottle had broken appeared a dark and irregular stain.

Then, without so much as a laugh, he stepped back through the door and raced down the stairs in pursuit of White. It was too late; the man had disappeared. Jack o' Judgment stood for a moment listening, then he slipped off the black coat and ripped off the mask. The coat was of the finest silk, for he rolled it into the space of a pocket-handkerchief and slipped it in his pocket. The handkerchief went the same way. If there had been observers, they would have caught a glimpse of a man in evening dress as he went swiftly down the half-lighted stairway.
