From The Perry Mason TV Show Book
Perry and Paul are off to Hawaii, the land of sun, fun, expensive beachfront property—and murder. Perry is tending to the legal problems of a land sale for Jarvis Logan, who wants to lease his beach to the Pan-Pacific hotel chain. Trouble is, he needs to gain control of Kamehameha Point, a peninsula that splits his holdings in two.

The disputed property will soon belong to a local girl named Anona Gilbert, as part of her inheritance. Anona is engaged to shady beachbum-surfer Douglas Kelland, who breaks off their engagement, but then calls Anona and asks her to meet him at his beach cottage. She arrives and finds Kelland dead, skewered with a spear. Paul arrives just in time to see Anona run away. The police think the girl killed Kelland over the jilt.
