That much, though no more, had, however, been fairly established overnight. It was a conclusion to which Mullins, with the facile conviction of his class, had jumped on the slender evidence of the asthma cigarette alone; but before midnight Thrush himself had been forced to admit its extreme probability. There was a medicine cork as well as an asthma cigarette; the medicine cork had been found very much nearer the body; in fact, just across the pathway, under a shrub on the other side of the fence. It was Mullins, who had made both discoveries, who also craved permission to ring up Dr. Bompas, late at night, to ask if there was any particular chemist to whom he sent his patients with their prescriptions. Dr. Bompas was not at home, which perhaps was just as well but his man gave the name of Harben, in Oxford Street. Harbens, rung up in their turn, found that they certainly had made up one of the doctor’s prescriptions on the Wednesday, for a young Mr. Upton, and, within half an hour, had positively identified the cork found by Mullins in Hyde Park. It was still sticky with the very stuff which had put poor Pocket asleep. Yet Thrush could not or would not conceive any actual connection between a harmless schoolboy and an apparently cold-blooded crime. He resisted the idea on more grounds than he felt disposed to urge in argument with his now strangely animated factotum. It was still a wide jump to a detestable conclusion, but he confined his criticism to the width of the jump. The cork and the cigarette might be stepping-stones, but at least one more was wanted to justify the slightest suspicion against the missing boy. Let it be shown that he had carried firearms on the Wednesday night, and Thrush undertook to join his satellite on the other side; but his mental bias may be gauged from the fact that he made no mention of the boy’s mother’s dream. Mullins found him not only up, shaved and booted, but already an enthusiastic convert to the startling theory of a sensation journalist, and consequently an irritable observer of the saturnine countenance which darkened to a tinge of distinct amusement over the leaded type. “So you don’t think there’s much in it, Mullins?” “I shouldn’t say there was anything at all, sir.” “Yet I suppose you remember the very similar occurrence in Holland Walk?” “Oh yes, sir, but it was a case of suicide.” “I don’t agree.” “But surely, sir, the jury brought it in suicide?”
