Micah Erlich hires Holmes to solve urgently the robbery of diamonds in David Batonvert's Manhattan exchange from his world-reputed security firm's top-range vault model, the 'impregnable' Leviathan, before the news wrecks the manufacturer. Both men remember it was actually cracked once four years ago by a brilliant team of four, who were tried and jailed, but draw different conclusions concerning a connection, which Holmes has to revise while his investigation progresses with the help of his own consultants. Meanwhile he helps Watson deal with her unexpectedly visiting family rather then cancel her buddy job with him.
