Robert McCaw grew up in a military family traveling the world. After graduating from Georgetown University, he served as a lieutenant in the US Army before earning his law degree from the University of Virginia. After law school he spent a year as a judicial clerk for Supreme Court Justice Hugo L. Black. Thereafter, he was a partner in a major international law firm with offices in Washington, DC, and New York City, representing clients in complex civil and criminal cases.
For a number of years, McCaw has maintained a home on the Big Island of Hawaiʻi, studying its history, culture, and people. In researching this book, he consulted with Hawaiʻi County cops and walked the streets, courthouse corridors, and parks where much of this story takes place. Over the past twenty years he has hiked extensively in Hawaiʻi Volcanoes National Park and roamed the back roads around nearby Volcano Village, where colorful characters living off the grid abound. Off the Grid is his second Koa Kāne Hawaiian Mystery. Bob lives with his wife, Calli, who is a photographer, in New York City and Hawaiʻi.
