"Because no one could have taken it out of his overcoat pocket there. I took the coat downstairs by mistake, but I'm sure I never abstracted the knife. Ezra Lazarus took it back, and I'll swear, in spite of Mr. Naball, he didn't take it. It's not likely Mortimer would go fiddling in another man's pockets, so I believe the knife was taken from the coat pocket, without his knowledge, at the club." "But who took it, and how?" asked Eugénie, with great interest. "My dear," replied Kitty, with a shrug, "how do I know. Perhaps, after receiving back the knife from Fenton, and putting it in his pocket, he hung his coat up again; in that case, anyone who saw him put the knife away could have stolen it." "But who would do so?" "That's what our clever Naball ought to find out," said Caprice, with a disdainful smile, "only he's such an idiot. I tell you whom I suspect--mind you, it's only suspicion--and yet appearances are quite as black against him as any one else." "Who is it?" "Malton." "Malton!" repeated Eugénie, starting up. "None other," said Kitty coolly. "He was at the club, and I know was hard up for money. His wife came to me one day, and told me he had embezzled a lot of money at his office. Then, after the crime, she came to me, and thanked me for paying it. I never did so. Fenton said he did, but I doubt it, as there isn't much of the philanthropist about him, so the only one who could have replaced the money was Malton himself. How? Well, easily enough. He was at the club--saw Keith's knife, and, knowing he was Lazarus's clerk, the idea flashed across his mind of murdering the old man with the knife, and dropping it about, so as to throw suspicion on Stewart. So, by some means, I don't know how, he obtains the knife before Stewart leaves the club, commits the crime, gets the money, circulates the notes, and when taxed with the possession of a marked one, says he got it from Ezra Lazarus--very weak, my dear, very weak indeed. Ezra says he paid him some money, so naturally doesn't know each individual note; so such a thing favours Mr. Malton's little plan. So there you are, my dear. I've made up a complete case against Malton, and quite as feasible as any of Naball's theories. Upon my word," said Kitty gaily, "I ought to have been a detective." Eugénie was walking to and fro hurriedly. "If this is so, he ought to be arrested," she said quickly. "Then go and tell Naball, my dear," said Kitty in a mocking voice. "He'll arrest any one on suspicion. I wonder half the population of Melbourne aren't in jail, charged with the murder. Oh, Naball's a brilliant man! He says the man who committed the murder stole my diamonds--pish!" "And you say Keith stole them," said Eugénie reproachfully, "therefore--" "Therefore the lesser crime includes the greater," finished Kitty coolly. "No, my dear, I don't believe he is a murderer; but as to the diamonds, what am I to think after what Meg told me?"
