A band of dangerous jewel thieves plans to raid a posh riverboat. A teenage girl is snatched by a murderous kidnapper,right out from her mother's nose. A young man is beaten, tortured and drowned in the dark river. Commander Georges Gideon, Scotland Yard's genius at detection, wades through a swamp of baffling clues only to discover., with alarm, that he may, already, be in well over his head... Gideon at his best and the Thames at its most diversified.
