A Timber Creek K-9 Mystery
Book Blurb:
Major crimes intersect in this nail-biting installment of the Timber Creek K-9 mysteries by award-winning author Margaret Mizushima.
A routine welfare check becomes a nightmare when Deputy Mattie Walker finds a young mother dead and a hysterical toddler, possibly the only witness to a brutal crime. Before the investigative team can start piecing together what happened, Mattie discovers another criminal act in Timber Creek.
During a traffic stop for speeding, Mattie observes a nervous driver and a teenage passenger frozen with fear. A quick sweep of the car with her K-9 partner, Robo, reveals a dangerous mix of drugs and suspected human trafficking, providing Mattie with grounds to arrest the driver. After she places the teenager in protective custody, the sheriff’s department hands the case over to the Colorado Bureau of Investigation.
As the team gathers evidence and information, Mattie’s husband, veterinarian Cole Walker, notices suspicious activity during ambulatory calls at dog kennels, indicating yet a third crime lurking in the shadows. What begins as isolated incidents quickly reveals a chilling truth: Organized crime has infiltrated their rural mountain community.
Every clue leads to more questions, and each answer brings them closer to greater danger. Do Mattie and her law enforcement partners have what it takes to shut down this criminal ring before it claims more victims? And could its next victim be someone Mattie loves?
My Review:
I don’t miss a chance to read the latest Timber Creek K-9 Mystery by Ms. Mizushima. I love the characters and have watched their growth almost from Book 1. The protagonist is Deputy Mattie Walker, of course, but the star (at least for me) is Robo, the German Shepherd.
This installment starts right off with a welfare check of a young mother who is found dead with her toddler crying nearby. As always, however, these K-9 stories are layered in between Mattie’s home life. She and the local veterinarian Cole Walker married and created a ready-made family with her step-daughters Sophie and Angie. Sophie is the youngest and easiest as Angie has progressed to sullen teen. The family recently underwent a collective trauma for which they are now consulting a therapist. Maddie’s job creates a bit of tension by duties that keep her from family sessions.
I love the parts where not only Robo, but Cole are used in her police investigations and procedures are often explained. It’s interesting how Mattie gets Robo psyched up for a pursuit, but usually just the Kevlar vest means that Robo is going to work. His demeanor changes instantly and he’s all business. Serious business.
The author has a talent for storytelling, describing her well-developed characters and tackling topical issues such as human trafficking as well as domestic issues. The people seem real—we’ve watched them grow and meld. The pacing doesn’t waver or slow and the plot builds tension and suspense as each episode thread is tackled.
It’s a series where each book can be read as a standalone, but also as an old friend when read from the beginning

The owner refuses to pay the cryptocurrency ransom, which has been given a time frame of midnight. It is the terror-stricken call from a college student subbing for a crew member who secreted himself below decks that forced the initial immediate action and call to multiple available teams.



The MC is Undersheriff Estelle Reyes-Guzman who is looking forward to retirement and counting the days. This tragedy, however, takes most of her focus as she is also wrestling with a vandal wreaking chaos and confusion. The MC appeared to me to be quick to judge, no one’s fool, seen it-been there, and had no patience for anyone she suspected of wrong doing. You wouldn’t want to cross her. This along with the usual internal issues of the department spells some slow time for the plot. 3.5 stars – CE Williams
