So they buried "Snow" Gregory, the unknown, and a jury of his fellow-countrymen returned a verdict of "Wilful murder against some person or persons unknown."
And that was the end of a sordid tragedy, it seemed, until three months later there dawned upon Colonel Boundary's busy life a brand new and alarming factor.
One morning there arrived at his palatial flat in Albemarle Place a letter. This he opened because it was marked "Private and Personal." It was not a letter at all—as it proved—but a soiled and stained playing card, the Knave of Clubs.
He looked at the thing in perplexity, for the fate of his erstwhile assistant had long since passed from his mind. Then he saw writing on the margin of the card, and twisting it sideways read:
"JACK O' JUDGMENT."
Nothing more!
"Jack o' Judgment!"
The colonel screwed up his tired eyes as if to shut out a vision.
"Faugh!" he said in disgust and dropped the pasteboard into his waste-paper basket.
For he had seen a vision—a white face, unshaven and haggard, its lips parted in a little grin, the smile of "Snow" Gregory on the last time they had met.
