Author: Robert McCaw
Published on: 4th January 2022
Genre: Mystery and Thrillers | Police Procedural
A volcanic earthquake disrupts a local, abandoned cemetery and unearths the mutilated body of a young woman. On searching the database and zeroing up on a few missing persons, Chief Detective Koa Kane and his team find the real identity of the victim. (The killer removed her fingertips so that IDing her would be difficult.)
At the same time – Bobby Hazzard makes an appearance in Hawaii. Bobby is the grandson of the man Koa killed three decades ago. Bobby’s gramps was no angel – he tortured his sugar cane factory workers and murdered Koa’s father. In return, Koa stalked the man, killed him and staged the murder as suicide. Three decades later, Bobby comes to the island and creates a scene – he believes his gramps was murdered and Bobby is going to unravel the truth at any cost…
Treachery Times Two is the fourth book in Robert McCaw’s Koa Kane Hawaiian Mystery series. Though each book in this series can be read as a standalone, I highly recommend you to start from book #1 if you are new to this series.
Koa Kane Mystery series is one of my all-time favorite detective series. Set in the mystical and beautiful island of Hawaii, the story revolves around a Chief Detective named Koa Kane, his personal life (the demons that keep him awake most nights) and gruesome crimes. The Hawaiian heritage is well-explained in all the books of this series – readers are in a visual treat, that’s for sure.
This is the second book of the series in which the volcano is somehow related to the crime scene. (There was another involving a volcanic eruption in a school.) But this time, Koa is in for ‘two birds with one stone’ kinda scenario. As the story ended, I felt ‘treachery times two, indeed.’
The mutilated body of a young woman is found in an abandoned cemetery. On combing through the database and searching through the mispers, Koa and his team find the identity of the dead woman and the organization she worked for. When Koa reaches her place of work, he’s not given any information. When Koa forces them to cooperate, Koa’s chief receives a call complaining about his behavior.
Meanwhile, the grandson of a man Koa murdered thirty years ago is on the island, looking for clues that might prove his gramps’ suicide to be murder. Koa must fight his demons once again, and this time he’s the threat is closer than he thinks. Would he lose his job, the love of his life (Nalani) and everything else for a mistake he committed as a teenager?
Treachery Times Two is another fantastic addition to the series. Excellent storytelling, perfectly-portrayed characters and, not one but two mysteries to keep one guessing till the end. As the title suggests, Koa realizes he’s been betrayed… twice.
The mystery behind the dead woman has something to do with her work (she worked for a defense contractor) while Bobby… well, the mystery behind Bobby Hazzard’s sudden appearance has something to do with Koa’s dark past. (Not as you think, though; as the story ends, Koa learns the real reason behind Bobby’s ‘curiosity’.)
Treachery Times Two by Robert McCaw is my first best read of 2022. I absolutely loved every bit of this story and I am looking forward to reading more of Koa Kane’s adventures. If you are looking for a police procedural set in the scenic Hawaiian islands, you might want to give this book a try. Believe me, you won’t be disappointed!

I really want to try this series for the setting in Hawaii and background particularly. The mysteries seem interesting too
Yes, the setting and the character (Koa) are the highlights of this series.😊 For a mystery classic Hawaiian setting, you can try Earl Biggers’ Charlie Chan series (available on fadedpages)
I’ve read the first two of those, liked them a lot. But still to complete the series.
I read the first one and had planned to binge read the other 5. Well, that was the plan I made two years ago…😂
Ha ha ha. Can understand. In the second Charlie Chan had more of a central role in the story. And if I remember right it takes place on mainland not Hawaii
