Book Review: The Rhythm of Evil by Dennis Koller

The Rhythm of Evil is a fast-paced, can’t put the book down, suspense thriller featuring Dennis Koller’s new hero, Reg Decker, Homicide Inspector. Decker was trained by the best in the business, retired Detective Tom McGuire, hero of Koller’s earlier books. Now Tom’s retired, but not entirely out of the picture.

Reg Decker is a seasoned San Francisco Homicide Inspector. He’s tough, he’s thorough, and he’s got heart. When nephew Bobby, a UCLA law student with cerebral palsy called to let Decker know about an explosion of destructive Twitter tweets about the Poppy Garcia murder, Uncle Reggie jumped into action only to discover more than he bargained for.

Decker’s partner for the past three years has been Manny Morales.  By coincidence, Morales was partner to Barry Egan, lead detective on the Poppy Garcia murder case. Egan left the department years ago, in a swirl of unanswered questions. A single mother, gang bangers, Mexican cartels, a pawn shop and dirty cops. So many questions.

Follow Inspector Decker through San Francisco’s avenues to the financial district, down Market Street, across the Golden Gate Bridge, and out to the greater Bay Area as the tangled strings of the past unravel. If you liked the Harry Bosch series by Michael Connelly, you’ll love this book.

The Rhythm of Evil is a top-notch thriller! The suspense escalates in Koller’s fast paced tale of a simple murder that turns out to be anything but simple. Tight writing and believable characters will keep the pages turning.  This exciting novel will be hot off the press on June 1. I can’t wait to read the next Inspector Reg Decker thriller!

  3. Always love a good mystery set in San Francisco; I recognized all the local venues having been born, raised and worked in the City By The Bay. Missed Tom Maguire, retired homicide inspector, the protagonist in earlier tomes, but Reggie Decker is more than a respectable replacement. The thriller wrapped up with a truly unexpected twist. What more could you ask for in a great mystey story?

    1. The Rhythm of Evil is a thrilling book with many twists and turns that capture the reader’s interest with surprising developments throughout. This is a well written page turner reminiscent of James Patterson’s books but even more riveting. The dogged determination of Inspector Reg Decker to solve a thirteen year old murder amidst a multitude of obstacles will keep the reader focused in every chapter. A great read-very hard to put down.
