London’s Hatton Garden is diamond alley for jewel traders. Deals are done behind shop fronts, on the street, at the kerbside. Diamond merchants carry their merchandise in their pockets to and fro, and that makes them vulnerable to predators. Hersolm Weinstock, 59, a Hatton Garden diamond merchant, was attacked and robbed near his home on the night of Monday, December 21st, 1942, in Ludlow Way, East Finchley. He died two days later in hospital.

Mr. Weinstock’s attacker must have followed him from his office and must have known he was carrying diamonds. They were worth £1,000 – which by today’s values would be around £50,000.
