CHAPTER II

THE SUSPECT

"I had better," said he, "give you a general outline of the case as it presents itself to the legal mind, and then my client, Mr. Reuben Hornby, can fill in the details if necessary, and answer any questions that you may wish to put to him.

"Mr. Reuben occupies a position of trust in the business of his uncle, John Hornby, who is a gold and silver refiner and dealer in precious metals generally. There is a certain amount of outside assay work carried on in the establishment, but the main business consists in the testing and refining of samples of gold sent from certain mines in South Africa.

"About five years ago Mr. Reuben and his cousin Walter—another nephew of John Hornby—left school, and both were articled to their uncle, with the view to their ultimately becoming partners in the house; and they have remained with him ever since, occupying, as I have said, positions of considerable responsibility.

"And now for a few words as to how business is conducted in Mr. Hornby's establishment. The samples of gold are handed over at the docks to some accredited representative of the firm—generally either Mr. Reuben or Mr. Walter—who has been despatched to meet the ship, and conveyed either to the bank or to the works according to circumstances. Of course every effort is made to have as little gold as possible on the premises, and the bars are always removed to the bank at the earliest opportunity; but it happens unavoidably that samples of considerable value have often to remain on the premises all night, and so the works are furnished with a large and powerful safe or strong room for their reception. This safe is situated in the private office under the eye of the principal, and, as an additional precaution, the caretaker, who acts as night-watchman, occupies a room directly over the office, and patrols the building periodically through the night.

"Now a very strange thing has occurred with regard to this safe. It happens that one of Mr. Hornby's customers in South Africa is interested in a diamond mine, and, although transactions in precious stones form no part of the business of the house, he has, from time to time, sent parcels of rough diamonds addressed to Mr. Hornby, to be either deposited in the bank or handed on to the diamond brokers.

"A fortnight ago Mr. Hornby was advised that a parcel of stones had been despatched by the Elmina Castle, and it appeared that the parcel was an unusually large one and contained stones of exceptional size and value. Under these circumstances Mr. Reuben was sent down to the docks at an early hour in the hope the ship might arrive in time for the stones to be lodged in the bank at once. Unfortunately, however, this was not the case, and the diamonds had to be taken to the works and locked up in the safe."

"Who placed them in the safe?" asked Thorndyke.
