Le repaire de la murène
André Franquin
 In The Moray's Keep, shipping magnate Xénophon Hamadryas offers a $ 6000 prize to the makers of a submarine innovation in order to find his sunken ship Le Discret off the French Mediterranean coast. The Count of Champignac's mini-sub invention is so spectacular that the competition must resort to sabotage. A chain of secrets need to be exposed while the maritime criminal John "the Moray" Helena lurks in the deep.
