"And if you hadn't I should probably have put the cypher aside until the case was over, and so have missed the whole thing. Another lesson never to despise what seem like trifles. If you have studied the cypher you have no doubt observed—but there, we'll talk that over afterwards, and the whole case if you like. I'll go now, and I'll tell you all about the business when time permits."

Here is the case of the bond robbery as it had been presented to Martin Hewitt that morning, while I was at St. Augustine's Hospital, and as I learned it from him later. I had been a little puzzled to hear Hewitt say that the case had seemed so desperately hopeless that he advised the calling in of the police, because my experience had rather been that it was Hewitt who was commonly called in—often too late—when the police were beaten, and I had never before heard of a case in which this order of things was reversed. It turned out, however, as will be seen, that in the state of the matter as it first presented itself the only measures that seemed possible were such as it was in the power of the police alone to adopt.

Messrs. Kingsley, Bell, and Dalton were an old-established firm of brokers whose operations were not enormous nor much in the eye of the public, but who carried on a steady and reputable business in a set of offices high up in a great building in Broad Street—a building so large that the notice "Offices to let" was a permanent fixture in the front porch. The firm's clients were chiefly steady-going investors of the old-fashioned sort, who wished to avoid all speculative fireworks, and to deal through a firm whose habits were conformable to their own. The last Kingsley had left the firm and soon afterward died, some few years back, and now the head of the firm was Mr. Robert Stanstead Bell, a gentleman of some sixty years of age. There were a couple of sleeping partners—relations—but the one other active partner was Mr. Clarence Dalton, a young man but recently advanced to partnership, and, it was said, likely to become Mr. Bell's son-in-law whenever the old gentleman's daughter Lilian should be married.

The steady, even round of business to which Kingsley, Bell, and Dalton, and their clerks were accustomed was suddenly interrupted by an appalling loss. It was discovered that bonds were missing from the safe, bonds to the amount of some £25,000; and whence, how, or when they were taken was an utter mystery. It was this loss which had occasioned the urgent message to Hewitt.

When Hewitt reached the spot he was shown at once into an inner office, where Mr. Bell sat waiting. The old gentleman was in a sad state of agitation, and it was with some difficulty that Hewitt got from him a reasonably connected account of the trouble.

"The loss comes at such a time, Mr. Hewitt," the senior partner explained, "that I don't know but it may ruin us utterly, unless my clients' property can be recovered. We have had to pay out heavy sums of late to the representatives of dead or retiring partners, and other circumstances combine with these to make the matter in this way even more terribly serious than the very large amount of the loss would seem to suggest. So I beg you will do what you can."

"That of course," responded Hewitt. "But please tell me, as clearly as you can, the precise circumstances of the case. Where were the bonds taken from?"

"This safe," Mr. Bell answered, turning toward a very large and heavy one, which might almost have been called a small strong room. "They were kept, together with others, in this box, one of several, as you see. The box was fastened, like the rest, with a Tripp's patent lever padlock, the only key of which I kept, together with the key of the safe."
