Robert McCaw grew up in a military family, traveling the world. He is a graduate of Georgetown University, served as a U.S. Army lieutenant, and earned a law degree from the University of Virginia. Having lived on the Big Island of Hawaii, McCaw’ s writing is imbued by his more than 20-year love affair with this Pacific paradise. In his new novel “Retribution,” the fifth in his Koa Kāne Hawaiian Mystery Series, Chief Detective Koa Kāne wonders if he might be the real target as people around him come under attack. Other books in the series include “Death of a Messenger,” “Off the Grid,” “Fire and Vengeance,” and “Treachery Times Two.” (Amazon, 2023)

“Retribution” – the story begins as an unknown Muslim man climbs off a Philippine freighter unto a speed boat with one goal in mind: to avenge his brother’s killing. Meanwhile, in the back alley of a bar on the Hawaii Island, a young man is found stabbed to death. When Hilo Chief Detective Koa Kāne begins investigating the crime, the murder weapon is conveniently recovered only a few feet away from the body. Crime scene technicians find fingerprints on the knife and they are a perfect match for Kāne’s younger brother, Ikaika. Even though his brother has a history of getting in trouble with the law, he has turned his life around, so Kāne is certain he is being framed for this crime. He is warned to stay out of the investigation, but of course he is determined to clear his brother’s name. During the investigation, another crime sends shockwaves through the Hilo police force. A sniper tries to take out Makanui, Kāne’s closest colleague. As Kāne tries to figure out whether these crimes are connected, the sinister force continues the killing spree, threatening him and his loved ones at every turn. Could Kāne be the real target? If so, who is behind this trail of retribution? With his own secret criminal past, he confronts an all-out offensive against those closest to him and his police force to which he has devoted his life. As the bodies pile up, Kāne finds himself the ultimate target of a ruthless adversary and must risk it all to survive.

Someone out there is determined to get to Detective Koa Kāne and is killing everyone connected to him. Not only is he still haunted by a secret he has kept all these years, he is constantly worrying about the safety of those around him but determined to catch a killer who seems to be one step ahead of him. On top of it all, he also needs to clear his brother’s name, and that further increases the conflict he feels between his police responsibilities and family loyalty. Since there are a couple of storylines, it can become challenging to follow along from time to time. The action is non-stop but perfectly balanced by the beauty of the Hawaiian location, which ironically enough, sometimes makes the investigation harder because some of the locations are remote and hard to access. With deeply developed and relatable characters, the story is mostly dialogue driven and flows from page to page until the suspenseful climatic ending. The highlight is Chapter 59 where the killer’s identity is revealed. As with his previous books, the author uses relevant Hawaiian terms and language, and even though he explains them as he goes along, it occasionally slows down the pacing, but it is worth it and readers are rewarded with a thrilling murder mystery filled with one plot twist after another. “Retribution” is another remarkable murder mystery by Robert McCaw and is recommended for fans of Michael Connelly who enjoy action thrillers revolving around terrorists and terrorist organizations. The good thing about this excellent mystery series is that each novel stands on its own and can be read in any order.

“The cave exploded with the roar of the gunshot, and the sound reverberated off the cave walls. Makanui’s bullet hit its mark and exited through the back of Cruz’s skull, leaving a golf-ball-sized hole and splattering Cruz’s brains into the lava tube behind him. His gun and hard hat went flying, plunging the cave into blackness.”
