Rh Frenchman of the South, and to pose as a servant of the French embassy. Reminiscent of the immortal Tartarin, his ready bureau furnished him with a stiff black moustache and some specially stout horsehair to typify the stubbly beard of that hero. When, at almost a quarter to four, he descended into the Inn with the parcel in his hand, a Baedeker and the envelope of tissues in his pocket, a cab was just setting down, and impulsively he chartered it as far as Exeter Hall. Concealed in the cab, he imagined he would the more readily escape observation, and by the time he alighted, flattered himself that any pursuit had been baffled. As he discharged the cab, however, he noticed a hansom draw up a few paces in the rear, whilst a man got out and began to saunter westward behind him. His suspicions alert, although the man was certainly a stranger, Pringle at once put him to the test by entering Romano's and ordering a small whiskey. After a decent delay, he emerged, and his pulse quickened when he saw a couple of doors off the same man staring into a shop-window! Pringle walked a few yards back, and then crossed to the opposite side of the street, but although he dodged at infinite peril through a string of omnibuses, he was unable to shake off his satellite, who, with unswerving persistence, occupied the most limited horizon whenever he looked back.

The instrument of settling such a score was in his hands, and rejecting his timorous doubts, he strode on, determined

to make one bold and final stroke for vengeance. The shadows had lengthened appreciably, and the quarter chiming from near St. Martin's warned him that there was no time to lose—the spy must be got rid of at any cost. Already could he see the estuary of the Strand, with the Square widening beyond; on his right loomed the tunnel of the Lowther Arcade, with its vista of juvenile delights. The sight was an inspiration. Darting in, he turned off sharp to the left into an artist's repository, with a double entrance to the Strand and the Arcade, and, softly closing the door, peeped through the palettes and frames which hung upon the glass. Hardly had they ceased swinging to his movement when he had the satisfaction of seeing the spy, the scent already cold, rush furiously up the Arcade, his course marked by falling toys and the
