Daren Chambers, wealthy owner of a car dealership in Hawaii, has been shot to death. His beautiful wife, Sally, co-owner and business partner, is terrified. She’s afraid that whoever killed Darren will be coming after her next--and she"s right. She hires Dick and George, the Payne and Clark Detective Agency, to investigate the killing. The police may be working on the who, but Sally is worried about the why. The killer has the same idea, and Dick and George scramble to protect her from bombs on Oahu, stalkers on Maui, murder on the Big Island, and machine guns on Kauai.
