The man in the fur coat, weary of steadying his drowsy head against the corner of his seat, sat upright and drew a newspaper from his pocket. Falling asleep over that, he produced a silver snuff-box, and refreshed himself with a generous pinch; then he looked meditatively at the old steward nodding comfortlessly before him, and proffered him the snuff-box; but looking into it, he discovered that it was about empty.

This appeared to afford him peculiar gratification, for he smiled to himself as he drew a paper parcel from his pocket, and proceeded to fill the snuff-box with its fragrant contents.

Idly Margaret watched him thrusting the diminished parcel back into the breast-pocket, and waking Purcell up by a vigorous poke, in order to offer him the replenished snuff-box.

The old man's eyes brightened, he uttered a heartfelt "I thank you kindly, sir," and inhaled a huge pinch, handing back the box with a courtly bow.

Then, sneezing with much fervor and wiping his eyes, Purcell vowed that he couldn't remember the day when snuff had smelt so queer; at which the man in the fur coat roared with laughter and boasted that his was the best; and presently Purcell's head sank down on his breast, and he took no further notice of his vis-a-vis.

Margaret drew out her handkerchief and covered her face with it, for a faint, sickening, drowsy odor was exhaling from Purcell's nostrils, and stealing her breath away.

She next tried her smelling-salts, and requested Purcell to open the window on his side: but he, taking no heed, she shook his arm, and, at last, gazed into his face.

It was chalk-white, a deadly perspiration bathed lip and brow; the half-closed eyelids showed the eyeballs glazed and sightless, and his breast heaved painfully, as if a ton-weight lay upon it.

Margaret Walsingham came to herself in an instant—she grew cool and calm.

She knew now that the man who sat opposite to her had been hired by Mortlake to murder her.
