But Bauer reasoned as a townsman, and Rudolf Rassendyll had the quick ear of a man bred in the country and trained to the woodland. All at once there was a jerk of his head; I know so well the motion which marked awakened attention in him. He did not pause nor break his stride: to do either would have been to betray his suspicions to his follower; but he crossed the road to the opposite side to that where No. 19 was situated, and slackened his pace a little, so that there was a longer interval between his own footfalls. The steps behind him grew slower, even as his did; their sound came no nearer: the follower would not overtake. Now, a man who loiters on such a night, just because another ahead of him is fool enough to loiter, has a reason for his action other than what can at first sight be detected. So thought Rudolf Rassendyll, and his brain was busied with finding it out. Then an idea seized him, and, forgetting the precautions that had hitherto served so well, he came to a sudden stop on the pavement, engrossed in deep thought. Was the man who dogged his steps Rupert himself? It would be like Rupert to track him, like Rupert to conceive such an attack, like Rupert to be ready either for a fearless assault from the front or a shameless shot from behind, and indifferent utterly which chance offered, so it threw him one of them. Mr. Rassendyll asked no better than to meet his enemy thus in the open. They could fight a fair fight, and if he fell the lamp would be caught up and carried on by Sapt’s hand or mine; if he got the better of Rupert, the letter would be his; a moment would destroy it and give safety to the queen. I do not suppose that he spent time in thinking how he should escape arrest at the hands of the police whom the fracas would probably rouse; if he did, he may well have reckoned on declaring plainly who he was, of laughing at their surprise over a chance likeness to the king, and of trusting to us to smuggle him beyond the arm of the law. What mattered all that, so that there was a moment in which to destroy the letter? At any rate he turned full round and began to walk straight towards Bauer, his hand resting on the revolver in the pocket of his coat.
