“On this occasion, the Bank were struck by something a little unusual about the sealing of the packet. It was opened, and found to contain knobs of sugar!

“Exactly how suspicion came to fasten on John Eardsley I do not know. It was remembered that he had been very wild at Cambridge and that his father had paid his debts more than once. Anyhow, it soon got about that this story of South American diamond fields was all a fantasy. John Eardsley was arrested. In his possession was found a portion of the De Beer diamonds.

“But the case never came to court. Sir Laurence Eardsley paid over a sum equal to the missing diamonds and De Beers did not prosecute. Exactly how the robbery was committed has never been known. But the knowledge that his son was a thief broke the old man’s heart. He had a stroke shortly afterwards. As for John, his fate was in a way merciful. He enlisted, went to the war, fought there bravely, and was killed, thus wiping out the stain on his name. Sir Laurence himself had a third stroke and died about a month ago. He died intestate and his vast fortune passed to his next of kin, a man whom he hardly knew.”
