A series of murders occur at the remote seaside mansion of a millionaire in Florida.  The mystery is heightened via local lore of pirates and hidden treasure, not to mention a fabled ancient octopus said to have a taste for the local black population.  It's up to grad student Ned Killdare, a budding naturalist and detective, to solve the case, aided by the rich man's pretty niece, Edith. - Summary by Matt Pierard
