Over Easter weekend 2015, a motley crew of six aging English thieves couldn't resist coming out of retirement for one last heist. Though not the smoothest of blokes, these analog crooks in a digital age managed to disable the Hatton Garden Safe Deposit's high-security alarm system and drill through 20 inches of reinforced concrete, walking away with a stunning haul of at least $21 million in jewels, gold, and cash. Drawing on sources at Scotland Yard as well as notorious figures from London's underworld, Dan Bilefsky offers a gripping account of how these unassuming masterminds nearly pulled off one of the greatest heists of the century.
