The real object of his visit and his flirtation at a Scotch castle filled his mind as, in the dull light of that fading afternoon, he swept along the muddy Great North Road his exhaust opened and roaring as he went ascending through Whetstone and Barnet in the direction of Hatfield. The “sixty” repainted cream with narrow gilt lines upon it certainly presented a very smart appearance, but in the back he had a couple of false number-plates, together with three big pots of dark-green enamel and a brush, so that if occasion arose, as it had arisen more than once, he could run up a by-road, and in an hour transform its appearance, so that its own maker would scarcely recognise it.

In the grey twilight as he approached Hitchin, swinging round those sharp corners at a speed as high as he dared, it poured with rain again, and he was compelled to lower the wind-screen and receive the full brunt of the storm, so blurred became everything through the sheet of plate-glass. The old “Sun” at Hitchin reached, he got a drink, lit his head-lamps, and crossing the marketplace, pushed forward, a long and monotonous run up Alconbury Hill and through Wansford to Stamford where, at the Stamford Hotel—which recalled memories of the Northovers—he ate a cold dinner and rested for an hour over a cigar.

Many were the exciting adventures he had had while acting as chauffeur to his Highness, but his instructions that morning had somehow filled him with unusual misgiving. He was on his way to pretend to make love to a girl whom he had never seen, the daughter of a millionaire shipbuilder, a man who, as the Prince had informed him, had risen from a journeyman, and like so many others who make money, had at once looked round for a ready-made pedigree, and its accompanying estate. Heraldry and family trees seem to exercise a strange and unaccountable fascination for the parvenu.

As he pushed north, on through that long dark night in the teeth of a bitter northeaster and constant rain, his mind was full of the mysterious coup which his Highness and his friend were about to attempt. Jewels and money were usually what they were in search of, but on this occasion it was something else. What it was, his Highness had flatly refused to tell.

Aided by the Rev. Thomas Clayton, one of the cleverest impostors who ever evaded the police, his Highness’s successes had been little short of marvellous. His audacity was unparalleled. The Parson, who lived constantly in that smug circle wherein moved the newly-rich, usually marked down the victim, introduced his Highness, or the fascinating Mr Tremlett, and left the rest to the young cosmopolitan’s tact and ingenuity. Their aliases were many, while the memory of both Tremlett and Clayton for faces was extraordinary. A favourite pose of the Prince was that of military attaché in the service of the German Government, and this self-assumed profession often gained him admission to the most exclusive circles here, and on the Continent.

Garrett’s alias of Herbert Hebberdine he had assumed on one or two previous occasions—once at Biarritz, when his Highness successfully secured the splendid pearl necklace of the Duchess of Taormino, and again a few months later at Abbazia, on the beautiful shore of the Adriatic. On both occasions their coup had been brought off without a hitch, he recollected. Therefore, why should he, on this occasion, become so foolishly apprehensive?

He could not tell. He tried to analyse his feelings as, hour after hour, he sat at the wheel, tearing along that dark, wet, endless highway due north towards York. But all in vain. Over him seemed to have spread a shadow of impending evil, and try how he would, he could not shake off the uncomfortable feeling that he was rushing into some grave peril from which he was destined not to escape.

To describe in detail that wet, uncomfortable run from Hyde Park Corner to Edinburgh would serve no purpose in this little chronicle of an exciting chapter of an adventurous life. Suffice it to say that, late in the night of the second day after leaving London, he drew up before the North British Hotel, in Prince’s Street, glad of shelter from the icy blast. A telegram from his Highness ordered him to arrive at the castle on the following evening; therefore, just as dusk was falling, he found himself before the lodge-gates of the splendid domain of the laird of Glenblair, and a moment later turned into the drive which ascended for more than a mile through an avenue of great bare beeches and oaks, on the one side a dense wood, and on the other a deep, beautiful glen, where, far below, rippled a burn with many picturesque cascades.

Once or twice he touched the button of the electric horn to give warning of his approach, when suddenly the drive took a wide curve and opened out before a splendid old mansion in the Scotch baronial style, situated amid the most romantic and picturesque scenery it had ever been his lot to witness.

At the door, brought out by the horn, stood his Highness, in a smart suit of blue serge, and the Parson, in severe clerical garb and pince-nez, while with them stood two women, one plump, elderly, and grey-haired, in a dark gown, the other a slim figure in cream with wavy chestnut hair, and a face that instantly fascinated the new-comer.
