He paused and looked at Spargo as if he was wondering what he ought or not to say to a newspaper man.  Spargo remained silent, waiting.  And presently Mr. Aylmore went on.

“I read your account in the Watchman this morning,” he said.  “I was wondering, when you called just now, if I would communicate with you or with the police.  The fact is—­I suppose you want this for your paper, eh?” he continued after a sudden breaking off.

“I shall not print anything that you wish me not to print,” answered Spargo.  “If you care to give me any information——­”

“Oh, well!” said Mr. Aylmore.  “I don’t mind.  The fact is, I knew next to nothing.  Marbury was a man with whom I had some—­well, business relations, of a sort, a great many years ago.  It must be twenty years—­perhaps more—­since I lost sight of him.  When he came up to me in the lobby the other night, I had to make an effort of memory to recall him.  He wished me, having once met me, to give him some advice, and as there was little doing in the House that night, and as he had once been—­almost a friend—­I walked to his hotel with him, chatting.  He told me that he had only landed from Australia that morning, and what he wanted my advice about, principally, was—­diamonds.  Australian diamonds.”

“I was unaware,” remarked Spargo, “that diamonds were ever found in Australia.”

Mr. Aylmore smiled—­a little cynically.

“Perhaps so,” he said.  “But diamonds have been found in Australia from time to time, ever since Australia was known to Europeans, and in the opinion of experts, they will eventually be found there in quantity.  Anyhow, Marbury had got hold of some Australian diamonds, and he showed them to me at his hotel—­a number of them.  We examined them in his room.”

“What did he do with them—­afterwards?” asked Spargo.  “He put them in his waistcoat pocket—­in a very small wash-leather bag, from which he had taken them.  There were, in all, sixteen or twenty stones—­not more, and they were all small.  I advised him to see some expert—­I mentioned Streeter’s to him.  Now, I can tell you how he got hold of Mr. Breton’s address.”

The two young men pricked up their ears.  Spargo unconsciously tightened his hold on the pencil with which he was making notes.

“He got it from me,” continued Mr. Aylmore.  “The handwriting on the scrap of paper is mine, hurriedly scrawled.  He wanted legal advice.  As I knew very little about lawyers, I told him that if he called on Mr. Breton, Mr. Breton would be able to tell him of a first-class, sharp solicitor.  I wrote down Mr. Breton’s address for him, on a scrap of paper which he tore off a letter that he took from his pocket.  By the by, I observe that when his body was found there was nothing on it in the shape of papers or money.  I am quite sure that when I left him he had a lot of gold on him, those diamonds, and a breast-pocket full of letters.”
