Murder at Makapu'u — Chip Hughes

In MURDER AT MAKAPU'U Kai Cooke investigates the fatal sea-cliff plunge of philanthropist Beatrice Ho, whose unattended death looks suspiciously attended. Kai flies to Moloka‘i to check on the alibis of her second husband, the PI's former client Dr. Gordon Grimes. When those alibis raise questions Grimes' stepdaughter confronts him and they face off on the cliff from which he claims his wife jumped. Did Grimes push her?  Kai is not so sure.  Then he finds a final piece of evidence that appears to clinch the case.  Not the case he expected.
