"W.F. Denson" was the complete name, followed by the line "Foreign and Commission Agent." This Hewitt read with some little difficulty, for the door was open, and on the threshold stood that same agitated Jew whom Hewitt had seen at the front door. A little less actively perturbed now, he was nevertheless still nervously pale. "Mr. Martin Hewitt?" he cried, while Hewitt was still only at the head of the stairs. "Is it Mr. Martin Hewitt?" Hewitt came quietly along the corridor, using eyes and ears as he came. The Jew was a man of middle height, very obviously Jewish, and with a slight accent that hinted a Continental origin. "I have just received your message," Hewitt said, "and, as you see, I am here with no delay. Is Mr. Denson in?" "No--good heafens no--I would gif anything if he was, Mr. Hewitt. Come in, do! I haf been robbed--robbed by Denson himself, wit'out a wort of doubt. It is terrible--terrible! Fifteen t'ousant pounds! It ruins me, Mr. Hewitt, ruins me! Unless you can recover it! If you recover it, I will pay--pay--oh, I will pay fery well indeed!" There was a characteristically sudden moderation of the client's emphasis when he came to the engagement to pay. Hewitt had observed it in other clients, but it did not disturb him. "First," he said, "you must tell me your difficulty. You say you have been robbed of fifteen thousand pounds----" "Tiamonts, Mr. Hewitt--tiamonts! All from the case--here is the case, empty----" "Let us be methodical. We will shut the door and sit down." Hewitt pressed his client into a chair and produced his note-book. "It will be better to begin at the beginning. First, I should like to know your name, and a few such particulars as that." "Lewis Samuel, Hatton Garden--150, Hatton Garden--tiamont merchant." "Yes. And what is your connection with Mr. Denson?" "Business--just business," Samuel responded. He pronounced it "pishness," and it seemed his favourite word. "Like this; I will tell you. I haf known him some time, and did at first small pishness. He bought a little tiamont and haf it set in pracelet, and he pay--straightforward pishness. Then he bought some very good paste stones, all set in gold, and he pay--quite straightforward pishness. At the same time he says, 'I am pishness man myself, Mr. Samuel,' he says, 'and I like to make a little moneys as well as pay out sometimes. Don't you want any little agencies done? I do all foreign commissions, and I can forwart and receive and clear at dock and custom house. If you send any tiamonts I can consign and insure--very cheapest rates to you, special. If you want brokerage or buy and sell for you, confidential, I can do it with lowest commission. Especially I haf good connection with America. I haf many rich Americans, principals and customers,' he says, 'and often I could do pishness for you when they come over.'" "By which he meant he might sell them diamonds?" Hewitt queried.
