An enigmatic philosophical novel where the reader is challenged to solve a riddle. What happened to the Knigh family? The five members of this writing family have disappeared from their cabin cruiser, the Uranus, which was found drifting at sea with blood marks on the hull. The only explanation would appear to be that one of the Knigh family had drowned the others before inflicting the same fate on himself? There are no clues except that all the Knighs have left behind their notebooks, manuscripts and poems. It is from these works in progress that the Maritime Investigator, the Criminologist and the Literary Expert, (who has written a thesis on "The Knigh Literary Family"), seek a solution to this enigma.
