The Drowned Queen

CAN EVEN THE AVENGERS PREVENT SABOTAGE ON THE MAIDEN VOYAGE OF THE "ATLANTIC QUEEN," THE FIRST SUBMARINE LUXURY LINER?
As cover for this assignment, British agent John Steed is ship's dancing instructor, while his beautiful new partner, Tara King, travels as ship's physiotherapist.
Surrounded by suspicious characters, such as the so-called magician's assistant, Miss Goldspangle, the ill-fated Mr. Funfinger, and that booming battle-ax Mrs. Thwaite-Funderpump, Steed and Tara make their hazardous way through various red-herrings -- and scaly green mermen --
STRAIGHT INTO THE JAWS OF DEATH!
