It seemed as if there must be something here to follow, and yet, perhaps he was mistaken. He had been the first man of the company at the front door after Mr. Holman turned the paper over, and they all had noticed the absence of the red mark. It had been simultaneous with the clicking of the door-latch and he had covered the ground from his seat to the door sooner than anyone else. He could swear he had seen the man get into the cab that stood almost in front of the house. He had lost no time in getting into his own car which was detailed for such an emergency, and in signalling the officer on a motor-cycle who was also ready for a quick call. The carriage had barely turned the corner when they followed, there was no other of the kind in sight either way but that, and he had followed it closely. It must have been the right carriage. And yet, when the man got out at the church he was changed, much changed in appearance, so that he had looked twice into the empty carriage to make sure that the man for whom he searched was not still in there hiding. Then he had followed him into the church and seen him married; stood close at hand when he put his bride into a big car, and he had followed the car to the house where the reception was held; even mingling with the guests and watching until the bridal couple left for the train. He had stood in the alley in the shadow, the only one of the guests who had found how the bride was really going away, and again he had followed to the station. He had walked close enough to the bridegroom in the station to be almost sure that mustache and those heavy eyebrows were false; and yet he could not make it out. How could it be possible that a man who was going to be married in a great church full of fashionable people would so dare to flirt with chance as to accept an invitation to a dinner where he might not be able to get away for hours? What would have happened if he had not got there in time? Was it in the least possible that these two men could be identical? Everything but the likeness and the fact that he had followed the man so closely pointed out the impossibility.
