Two fake cops rang a buzzer and, in 81 minutes, stole $500M from Boston’s Gardner Museum—Rembrandt’s only seascape and Vermeer’s The Concert. They duct-taped two guards, took 13 works, skipped Titians, grabbed a random bronze beaker and an eagle finial, then vanished in St. Patrick’s Day chaos. Decades later, no arrests, no paintings; the FBI says the thieves are likely dead, empty frames still hang at the Isabella Stewart Gardner Museum, and a $10M reward still waits for Rembrandt’s Storm on the Sea of Galilee, Vermeer, and Degas.
