A smart hansom brought Hewitt to Threadneedle Street in a bare quarter of an hour, and there a few minutes' talk with the manager, Mr. Lyster, put him in possession of the main facts of the case, which appeared to be simple. Charles William Laker was twenty-five years of age, and had been in the employ of Messrs. Liddle, Neal & Liddle for something more than seven years--since he left school, in fact--and until the previous day there had been nothing in his conduct to complain of. His duties as walk-clerk consisted in making a certain round, beginning at about half-past ten each morning. There were a certain number of the more important banks between which and Messrs. Liddle, Neal & Liddle there were daily transactions, and a few smaller semi-private banks and merchant firms acting as financial agents, with whom there was business intercourse of less importance and regularity; and each of these, as necessary, he visited in turn, collecting cash due on bills and other instruments of a like nature. He carried a wallet, fastened securely to his person by a chain, and this wallet contained the bills and the cash. Usually at the end of his round, when all his bills had been converted into cash, the wallet held very large sums. His work and responsibilities, in fine, were those common to walk-clerks in all banks. On the day of the robbery he had started out as usual--possibly a little earlier than was customary--and the bills and other securities in his possession represented considerably more than £15,000. It had been ascertained that he had called in the usual way at each establishment on the round, and had transacted his business at the last place by about a quarter-past one, being then, without doubt, in possession of cash to the full value of the bills negotiated. After that, Mr. Lyster said, yesterday's report was that nothing more had been heard of him. But this morning there had been a message to the effect that he had been traced out of the country--to Calais, at least, it was thought. The directors of the society wished Hewitt to take the case in hand personally and at once, with a view of recovering what was possible from the plunder by way of salvage; also, of course, of finding Laker, for it is an important moral gain to guarantee societies, as an example, if a thief is caught and punished. Therefore Hewitt and Mr. Lyster, as soon as might be, made for Messrs. Liddle, Neal & Liddle's, that the investigation might be begun.
