内容简介：
A cold-blooded murder was just committed on a luxurious British cruise ship returning from the sun-drenched Caribbean islands of Martinique, Barbados, and St. Maarten. The ship's controller was bludgeoned with a ten-pound dumbbell in the fitness center. The victim was an especially nasty character who took great pleasure in advising headquarters which departments on the "Pegasus" fell short of their monetary goals. It's no wonder he was killed. Alec DunBarton, a Scottish bank auditor, comes to the rescue of Flagship Cruise Line to examine the controller's books. Although Alec is haunted by his past, he soon finds himself totally at home on the "Pegasus"-drinking Glenlivet, smoking his pipe, and singing whenever the spirit moves him. By means of song lyrics, Alec's able to decipher clues and describe his suspects. Was it the slick cruise director, the adulterous plumber, the mild-mannered security officer, the lonely cruise consultant, the plump masseuse, the seductive fitness instructor, or the wealthy passenger? If you're ready for adventure, come aboard. They're all expecting you
