Robert McCaw is an American author who graduated from Georgetown University and served as a lieutenant in the US Army before earning his law degree from the University of Virginia. He was a partner in a major international law firm with offices in Washington, DC and New York City and maintained a home on the Big Island of Hawai’i. This allows him to bring a unique authenticity to his Koa Kāne Hawaiian mystery novels in both his law enforcement expertise and his ability to portray the richness of Hawai’i’s history, culture and people. “Death of a Messenger” is the first book in the series and the second, “Off the Grid” is due out on Tuesday July 2. In “Off the Grid” Hilo police Detective Koa Kāne investigates two deaths that at first seem unrelated but when he discovers how they are linked, the crimes could rewrite history or cost him his career.

Chapter One of “Off the Grid” begins on a poetic note “The plume of smoky steam rising like a sulfur cloud from a volcanic vent told Hilo Chief Detective Koa Kāne he’d been called to a nasty scene” but ends with a staged accident that left a woman dead. That leads him to the second murder of the day: the tortured remains of an unfortunate soul left to burn in the path of an advancing lava flow. He soon discovers that the two murders are related when they turn out to be a reclusive couple living off the grid. They are mysterious fugitives, so naturally the CIA, the Chinese government and the Defense Intelligence agency try to impede all attempts to get to the truth of who wanted this couple dead. Despite growing political pressure, Koa digs further only to find himself drawn into a web of international intrigue. His investigation uncovers a government conspiracy that culminates in the arrest of Nāinoa Nihoa, the Hawai’i state representative running for governor, for murder in the deaths of the couple.

Robert McCaw brings the beauty of Hawai’i to the average reader and softens an otherwise grisly tale of murder and conspiracy. Espionage, treason and murder makes for a fascinating read and the action flows effortlessly through the pages. The language is easy to read and understand including the law enforcement and military lingo. An interesting detail is that the protagonist, Hilo Detective Chief Koa Kāne has a secret: as a young man, he killed a sugar mill manager to exact revenge on behalf of his father. He still feels guilt and remorse, yet he has not told anyone, including his girlfriend, and it affects his crime solving decisions. How long will it take for the secret to catch up to him? Stay tuned. “Off the Grid” is an intriguing crime mystery novel with enough plot twists to keep the reader turning pages until its jaw dropping ending. It is recommended for fans of mystery/crime novels with a flawed leading man who would not mind learning a thing or two about Hawai’i’s culture and its people. A definite must-read.
