With a suddenness that took him quite off his guard he was seized from behind. His arms were pinioned in a firm grip, whilst another man, holding a revolver, went through his pockets. As becomes an outraged Englishman, whether he be plebeian or aristocrat, Raife swore violently, and struggled viciously. At length, the man who searched his pockets, said: "It's all right, sir, he's got no weapon or arms." Still holding the pistol in front, his arms were released from behind. Raife turned to face the man with the iron grip who had pinioned him so easily. Both men gave a start and an exclamation of surprise. "Good heavens! Herrion--Inspector--what's the meaning of this?" demanded Raife. "Well," said Inspector Herrion, for it was he, the immaculate Scarlet Pimpernel of Scotland Yard, "we hardly expected, Sir Raife, to find you here, at this hour of the night." Raife laughed, and said: "I couldn't sleep, so I took a stroll." "Rather a long stroll, Sir Raife, from St James's to the Mall, Hammersmith, in the middle of the night," said Herrion with a curious smile. "May I call on you in the morning, sir?" he added. "Why to be sure, I'll be delighted to see you. But leave that infernal grip of yours behind," and they both laughed. At this moment there was a trampling of bushes in the garden behind, the swinging and slamming of a heavy iron gate, and then a shout: "Stop him!" A cloaked form, with flowing tie, dashed past a few yards from where the trio stood. They joined in hot pursuit, but the Apache, for it was he, was fleet of foot and had a good start. Further, he seemed to know every alley and byway in this maze of wharves and streets. Taking part in the chase, Raife was handicapped by his ignorance of the neighbourhood, and, at the outset, ran into a post in the dark and placed himself _hors de combat_ in the matter of speed. Raife was a runner, but to charge full tilt into a post was a sore handicap. After a while, Herrion, the dapper, little detective-inspector, was the only one left in the chase, and he ran as well as the Apache, but the Apache had the start, and, with the inherited cunning of his breed, understood the art of doubling. The inspector was unfamiliar with these alleys and slums, and it looked as though the Apache had got clean away. They came to a _cul de sac_ and there was no trace of him. With the consummate skill of his class, he had vanished into space and was gone. The two policemen and Raife retraced their steps and met other officers. Herrion was not the type of man to abandon his quarry without taxing his extraordinary resources to the end. He deployed his men to the best of their knowledge of the locality.
