The constables, after putting the corpse in a hackney coach, proceeded to the room; but it was dark and empty. They had no directions to do anything more that night, and returned to Bow Street. The next morning, however, as soon as it was light, a Secretary of State’s warrant, backed by sufficient force, was presented at the lodgings of Caillaud and Zachariah. The birds had flown, and not a soul could tell what had become of them. In Zachariah’s street, which was rather a Radical quarter, the official inquiries were not answered politely, and one of the constables received on the top of his head an old pail with slops in it. The minutest investigation failed to discover to whom the pail belonged. CHAPTER IX A STRAIN ON THE CABLE BOW STREET was completely at fault, and never discovered the secret of that assassination. It was clear that neither the Major nor Coleman were the murderers, as they had been noticed at some distance from the spot where the Secretary fell by several persons who described them accurately. Nor was Caillaud suspected, as the constable testified that he passed him on the opposite side of the street, as he followed the Secretary. The only conclusion, according to Bow Street, which was free from all doubt was, that whoever did the deed was a committee consisting of a single member. A reward of £500 did not bring forward anybody who knew anything about the business. As for Caillaud, his daughter and the Major, the next morning saw them far on the way to Dover, and eventually they arrived at Paris in safety. Zachariah, when he reached home, found his wife gone. A note lay for him there, probably from the same hand which warned the Major, telling him not to lose an instant, but to join in Islington one of the mails to Manchester. His wife would start that night from St. Martin’s le Grand by a coach which went by another road. He was always prompt, and in five minutes he was out of the house. The fare was carefully folded by his unknown friend in the letter. He just managed as directed, to secure a place, not by the regular Manchester mail, but by one which went through Barnet and stopped to take up passengers at the “Angel.” He climbed upon the roof, and presently was travelling rapidly through Holloway and Highgate. He found, to his relief, that nobody had heard of the murder, and he was left pretty much to his own reflections. His first thoughts were an attempt to unravel the mystery. Why was it so sudden? Why had no word not hint of what was intended reached him? He could not guess. In those days the clubs were so beset with spies that frequently the most important resolutions were taken by one man, who confided in nobody. It was winter, but fortunately Zachariah was well wrapped up. He journeyed on, hour after hour, in a state of mazed bewilderment, one thought tumbling over another, and when morning broke over the flats he had not advanced a single step in the
