While enjoying a leisurely ocean cruise in the company of secretary
Della Street, Perry Mason is approached by passenger who is worried
about the wellbeing of her husband. Not long afterward, her husband is
seen jumping off the ship, an apparent suicide--but when the body is
recovered, it turns out that he was shot. Accused of murder, the wife
puts her fate in the hands of Perry, who in the course of piecing things
together unearths the fact that the husband had once accepted a huge
bribe while serving on a jury. The case takes many shocking twists and
turns before revealing its surprising conclusion.
