“The evidence for the Royal plaintiff was simple enough. It all went to prove that the very day after the burglary not a jeweller, pawnbroker, or diamond merchant throughout the whole of Europe could have failed to know that a unique _parure_ of black diamonds had been stolen, and would probably be offered for sale. The Black Diamonds in themselves, and out of their setting, were absolutely unique, and if the late Mr. Vanderdellen purchased them in Paris from some private individual, he must at least have very strongly suspected that they were stolen. “Throughout the whole of that first day Mrs. Vanderdellen sat in court, absolutely calm and placid. She listened to the evidence, made little notes, and chatted with two or three American friends—elderly men—who were with her. “Then came the turn of the defence. “Everybody had expected something sensational, and listened more eagerly than ever as the name of Mr. Albert V. B. Sedley was called. He was a tall, elderly man, the regular angular type of the American, with his nasal twang and reposeful manner. “His story was brief and simple. He was a great friend of the late Mr. Vanderdellen, and had gone on a European tour with him in the early spring of 1902. They were together in Vienna in the month of March, staying at the Hotel Imperial, when one day Vanderdellen came to his room with a remarkable story. “‘He told me,’ continued Mr. Albert V. B. Sedley, ‘that he had just purchased some very beautiful diamonds, which he meant to present to his wife on his return to New York. He would not tell me where he bought them, nor would he show them to me, but he spoke about the beauty and rarity of the stones, which were that rarest of all things, beautiful black diamonds. “‘As the whole story sounded to me a little bit queer and mysterious, I gave him a word of caution, but he was quite confident as to the integrity of the vendor of the jewels, since the latter had made a somewhat curious bargain. Vanderdellen was to have the diamonds in his keeping for three months without paying any money, merely giving a formal receipt for them; then, if after three months he was quite satisfied with his bargain, and there had been no suspicion or rumour of any kind that the diamonds were stolen, then only was the money, £500,000, to be paid. “‘Vanderdellen thought this very fair and above-board, and so it sounded to me. The only thing I didn’t like about it all was that the vendor had given what I thought was a false name and no address; the money was to be paid over to him in French notes when the three months had expired, at an hotel in Paris, where Vanderdellen would be staying at the time, and where he would call for it.
