Close-up of the headstone of the supposed grave in Milton Cemetery, Portsmouth, of Lieutenant Commander Lionel Kenneth Phillip 'Buster' Crabb (1909-1956), British Royal Naval frogman and MI6 diver (some would say sabotage agent and alleged double-agent), who disappeared during a reconnaissance mission investigating the Soviet cruiser Ordzhonikidze in Portsmouth Harbour. A body was found months later, but it was difficult to identify as the head and hands were missing.
