"Come in," he commanded briefly.

The boy obeyed. Surreptitiously he wiped the wet and mud from his face and tried to reduce his wild breathing.

The room which he entered was meagre and stale-smelling, with bare floor and stained and sagging wall-paper; unfurnished save for a battered deal table and some chairs.

He sank into one of them and stared with frank curiosity past his employer, who had often entrusted him with messages requiring secrecy, past his employer's companion, to the third figure in the room. A prostrate figure which lay quite still under the heavy folds of a long dark ulster with its face turned to the wall.

"Well?" It was a singularly agreeable voice which aroused him, softly modulated but with a faint foreign accent. The speaker was his employer, a slender dark man, with a finely carved face, immobile as the Sphinx. He had laid aside his Inverness and top hat, and showed himself in evening dress with a large buttonhole of Parma violets, which sent forth a faint, delicious fragrance.

Of the personality of the man the messenger knew nothing more than that he was an aristocratic young nob, eccentric in a quiet way, who lived in a grand house near Portland Place, and who rewarded him handsomely for his occasional services.

He related his adventures of the evening, not omitting to mention his late pursuer. "The keb's waitin' now, outside, sir," he concluded.

The man listened quietly, brooding, his elbows upon the table, his inscrutable face propped in the crotch of his hand. A ruby, set quaintly in a cobra's head, gleamed from a ring upon his little finger. Presently he roused.

"That's all to-night, my boy," he said gravely. "You've served me well."

He drew out his purse, extracted two sovereigns, and laid them in the messenger's hand.
