He led the way to the room where the body had been found, and paused before the four-armed idol. "Here's our old friend Hachiman," he said, "whom you half fancied might have had something to do with the tragedy. Well, you were right. Hachiman had a good deal to do with it, and with the various disasters at Copleston's too. I will show you how."
The figure, which was larger than life-size, had been set up temporarily on a large packing-case, hidden by a red cloth covering. Hachiman was represented in the familiar Japanese kneeling-sitting position, and the carving of the whole thing was of an intricate and close description. The god was represented as clad in ancient armour, with a large and loose cloak depending from his shoulders and falling behind in a wilderness of marvellously and deeply carved folds.
"See here," Dorrington said, placing his fingers under a projecting part of the base of the figure, and motioning to Mr. Colson to do the same. "Lift. Pretty heavy, eh?"
The idol was, indeed, enormously heavy, and it must have required the exertions of several strong men to place it where it was. "It seems pretty solid, doesn't it?" Dorrington continued. "But look here." He stepped to the back of the image, and, taking a prominent fold of the cloak in one hand, with a quick pull and a simultaneous rap of the other fist two feet above, a great piece of the carved drapery lifted on a hinge near the shoulders, displaying a hollow interior. In a dark corner within a small bottle and a fragment of rag were just visible.
"See there," said Dorrington, "there wouldn't be enough room in there for you or me, but a small man—a Japanese priest of the old time, say—could squat pretty comfortably. And see!"—he pointed to a small metal bolt at the bottom of the swing drapery—"he could bolt himself safely in when he got there. Whether the priest went there to play the oracle, or to blow fire out of Hachiman's mouth and nose I don't know, though no doubt it might be an interesting subject for inquiry; perhaps he did both. You observe the chamber is lined with metal, which does something towards giving the thing its weight, and there are cunning little openings among the armour-joints in front which would transmit air and sound—even permit of a peep out. Now Mr. Deacon might or might not have found out this back door after the figure had been a while in his possession, but it is certain he knew nothing of it when he bought it. Copleston knew nothing of it, though the thing has stood in his place for months. You see it's not a thing one would notice at once—I never should have done so if I hadn't been looking for it." He shut the part, and the joints, of irregular outline, fell into the depths of the folds, and vanished as if by magic.
"Now," Dorrington went on, "as I told you, Copleston knew nothing of this, but one of his men found it out. Do you happen to have heard of one Samuel Castro, nicknamed 'Slackjaw,' a hunchback whom Copleston employed on odd jobs?"
"I have seen him here. He called, sometimes with messages, sometimes with parcels. I should probably have forgotten all about him were it not that he was rather an extraordinary creature, even among Copleston's men, who are all remarkable. But did he——"
"SLACKJAW."
"He murdered Mr. Deacon, I think," Dorrington replied, "as I fancy I can explain to you. But he won't hang for it, for he was drowned this afternoon before my eyes, in an attempt to escape from the police. He was an extraordinary creature, as you have said. He wasn't English—a half-caste of some sort I think—though his command of language, of the riverside and dock description, was very free; it got him his nickname of Slackjaw among the longshoremen. He was desperately excitable, and he had most of the vices, though I don't think he premeditated murder in this case—nothing but robbery. He was immensely strong, although such a little fellow, and sharp in his wits, and he might have had regular work at Copleston's if he had liked, but that wasn't his game—he was too lazy. He would work long enough to earn a shilling or so, and then he would go off to drink the money. So he was a sort of odd on-and-off man at Copleston's—just to run a message or carry something or what not when the regular men were busy. Well, he seems to have been smart enough—or perhaps it was no more than an accident—to find out about Hachiman's back, and he used his knowledge for his own purposes. Copleston couldn't account for missing things in the night—because he never guessed that Castro, by shutting himself up in Hachiman about closing time, had the run of the place when everybody had gone, and could pick up any trifle that looked suitable for the pawnshop in the morning. He could sleep comfortably on sacks or among straw, and thus save the rent of lodgings, and he could accept Hachiman's shelter again just before Copleston turned up to start the next day's business. Getting out, too, after the place was opened, was quite easy, for nobody came to the large store-rooms till something was wanted, and in a large place with many doors and gates, like Copleston's, unperceived going and coming was easy to one who knew the ropes. So that Slackjaw would creep quietly out, and in again by the front door to ask for a job. Copleston noticed how regular he had been every morning for the past few months, and thought he was getting steadier! As to the things that got smashed, I expect Slackjaw knocked them over, getting out in the dark. One china vase, in particular, had been shifted at the last moment, probably after he was in his hiding-place, and stood behind the image. That was smashed, of course. And these things, coming after the bad voyage of the ship in which he came over, very naturally gave poor Hachiman an unlucky reputation.
