  • Two brutal murders, a menacing band of poachers, and a fearsome creature on the loose in the mountains plunge Mattie Cobb and her K-9 partner Robo into a sinister vortex.

    An explosion outside a community dance sends Mattie Cobb and Cole Walker reeling into the night, where they discover a burning van and beside it the body of outfitter Nate Fletcher. But the explosion didn’t kill Nate—it was two gunshots to the heart.

    The investigation leads them to the home of rancher Doyle Redman, whose daughter is Nate’s widow and the object of one of their suspect’s affection. But before they can make an arrest, they receive an emergency call from a man who has been shot in the mountains. Mattie and Robo rush to the scene, only to be confronted by the ominous growl of a wild predator.

    As new players emerge on the scene, Mattie begins to understand the true danger that’s enveloping Timber Creek. They journey into the cold, misty mountains to track the animal—but discover something even more deadly.

  • On a rugged Colorado mountain ridge, Mattie Cobb and her police dog partner Robo make a grisly discovery―and become the targets of a ruthless killer.

    Colorado’s Redstone Ridge is a place of extraordinary beauty, but this rugged mountain wilderness harbors a horrifying secret. When a charred body is discovered in a shallow grave on the ridge, officer Mattie Cobb and her K-9 partner Robo are called in to spearhead the investigation. But this is no ordinary crime―and it soon becomes clear that Mattie has a close personal connection to the dead man.

    Joined by local veterinarian Cole Walker, the pair scours the mountaintop for evidence and makes another gruesome discovery: the skeletonized remains of two adults and a child. And then, the unthinkable happens. Could Mattie become the next victim in the murderer’s deadly game?

    A deranged killer torments Mattie with a litany of dark secrets that call into question her very identity. As a towering blaze races across the ridge, Cole and Robo search desperately for her―but time is running out.

  • Deputy Mattie Cobb is in a dark place and has withdrawn from Cole Walker and his family to work on issues from her past. When she and her K-9 partner, Robo, get called to track a missing junior high student, they find the girl dead on Smoker’s Hill behind the high school, and Mattie must head to the Walker home to break the bad news. But that’s only the start of trouble in Timber Creek because soon another girl goes missing—and this time it’s one of Cole’s daughters.

    Knowing that each hour a child remains missing lessens the probability of finding her alive, Mattie and Robo lead the hunt while Cole and community volunteers join in to search everywhere, but to no avail. It seems that someone has snatched all trace of the Walker girl from their midst, including her scent. Grasping at straws, Mattie and Robo follow a phoned-in tip into the dense forest, where they hope to find a trace of the girl’s scent and to rescue her alive. But when Robo does catch her scent, it leads them to information that challenges everything they thought they knew about the case.

    Mattie and Robo must rush to hunt down the kidnapper before they’re too late in Hunting Hour, the third installment in critically acclaimed author Margaret Mizushima’s exhilarating mystery series.

  • The next thrilling installment in the Timber Creek K-9 Mysteries

    When Deputy Ken Brody’s sweetheart goes missing in the mountains outside Timber Creek, Mattie Cobb and her K-9 partner Robo are called to search. But it’s mid-October and a dark snow storm is brewing over the high country. And they’re already too late. By the time they find her body, the storm has broken and the snow is coming down hard.

    While Brody hikes down to bring back the forensics team and veterinarian Cole Walker gathers supplies to protect them from the storm, Mattie and Robo find themselves alone, guarding the gravesite overnight in the dead of the early winter. And that’s only the first long, dark night in a series of them, because as their investigation develops, Mattie, Robo, Brody, and Cole find themselves in the middle of the killer’s stalking ground—where the hunters become the hunted.

    An engrossing listen filled with tension, excitement, and heart, Stalking Ground, the second in Margaret Mizushima’s lauded debut series, will send a chill down every listener’s spine.

  • When a young girl is found dead in the mountains outside Timber Creek, lifelong resident Officer Mattie Cobb and her partner, K-9 police dog Robo, are assigned to the case that has rocked the small Colorado town.

    With the help of Cole Walker, a local veterinarian and single father, Mattie and Robo must track down the truth before it claims another victim. But the more Mattie investigates, the more she realizes how many secrets her town holds. And the key may be Cole’s daughter, who knows more than she’s saying.

    The murder was just the beginning, and if Mattie isn’t careful, she and Robo could be next.

    Suspenseful and smart, Killing Trail is an explosive debut that will have listeners clamoring for more Mattie and Robo for years to come.
