Blood on the Reins by Brett Shayler is a mystery novel set in the competitive world of cutting horses. Shayler combines a murder investigation with horse culture and produces a unique yet familiar story.
Cade Mercer is a former cutting-horse champion. He thought he had left that part of life in the past, but life takes a swift turn when equestrian judge Dalton Rusk is found dead. His death is suspicious, and Cade decides he must find out the truth. His investigation reopens the hard reality of the cutting horse arena and leads Cade into something bigger than he imagined.
Blood on the Reins is set in an equestrian world, laid out nicely for readers. He does not use his setting as a backdrop filled with the mythical western world of cowboys. It is an integral part of the story that shows how the competitive world of horses is not merely a sport. This world is an institution.
Shayler’s tale is also an example of how bloodlines, reputations, and unwritten rules are bound up in the worldly picture of a sport built on trust, loyalty, and prestige. His story brings out themes of loyalty, honesty, and justice. These themes also make us consider how we are living and conducting ourselves in the world in general.
The set of characters in Blood on the Reins is well thought out. Cade is a man who has been on the inside. He knows the ins and outs of the horse world and is the perfect protagonist. Shayler also creates an investigative partnership with the notes of Sarah Jenkins, a former horsewoman who has died, and the insider Laney McCrae.
Blood on the Reins is part of Brett Shayler’s Cade Mercer Mystery series, and stands out as a crime thriller set in a world often overlooked in literature. Shayler has clearly given readers a story that is not just wrapped up in the who-done-it; rather, we have a novel that clearly shows the relationship between people and the institutions they serve. He has woven together his setting, characters, and themes to create a timely tale. Equestrian enthusiasts and readers of crime thrillers will enjoy and appreciate Blood on the Reins.
