A National Competition and a Deadly Detour
High school teacher Katie Wilk is thrilled when her students qualify for Mock Trial America, a prestigious courtroom competition in Atlanta. Alongside her best friend and fellow teacher Jane Mackey, a team of eager teens, and a crew of devoted chaperones, Katie boards a flight from Minnesota—ready for a week of intellectual showdowns and Southern hospitality. But things go sideways before the plane is even off the ground.
With canceled flights, endless delays, and one particularly obnoxious passenger stirring up trouble, the trip turns into a logistical, almost deadly, nightmare. When that same rude traveler turns up later in Atlanta, the chaos takes a deadly turn—and suspicion lands squarely on the Mackey family.
As Katie digs deeper, she uncovers a web of secrets: stolen documents, corporate espionage, dangerous toxins, and enough motive to make her question everything. Can she untangle the truth before the killer strikes again?
Luckily, she’s got help—from Maverick, her sharp-nosed, loyal Labrador retriever and trained search-and-rescue dog, who’s always ready to sniff out danger.
Smart, suspenseful, and full of heart, this latest installment in Mary Seifert’s charming cozy mystery series delivers Southern intrigue, tricky puzzles, and the kind of dogged determination only a Lab (and a resolute teacher) can provide.

EXCERPT
In reality, rushing water poured into the pond next to us, and plumes pounded the base of the falls, feeding the swiftly moving water in front of us. It burbled over substantial boulders and rocks and looked no less intimidating than any other spot.
Wendell removed his shoes, stuffed his socks inside, tied the laces, and hung them around his neck. He rolled up his pants legs and nodded. “You might want to do the same.”
The last remnants of the rainwater had evaporated from my clothes, and I couldn’t imagine getting wet all over again. I reluctantly removed my shoes and socks, crusty with dried mud, leaves, and burrs.
Wendell pocketed the gun, descended to the water’s edge, and stepped from the shore to the nearest flat stone, teetered, then caught his balance. He took another step. And another. The words he called over his shoulder were almost lost in the cacophony surrounding us. “It’s fine.”
I had few options. I tied the laces of my shoes together in front of me around the straps of my backpack to help keep it secure and took a deep breath. The staff acted like a third leg, and the first steps were easy, but the chilly splashes caused me to shiver, and midway across, I slid on a stone, slimy with lichen, dropped the stick, and pitched into the unexpectedly deep torrent of water.
My body slammed into the ice-cold river, forcing the air from my lungs. I couldn’t get my footing and fought to take a breath as the strong current carried me along and quickly swept me downstream, away from Wendell. I bounced against hard, stationary items submerged below the surface, pummeled from side to side, and could almost hear dinging as if hitting the bumpers on a pinball machine. The turbulence in the water increased, rippling and foamy. The surge dragged me under. I came up sputtering and inhaled a mouthful of water before the world around me spun out of control.
I couldn’t catch my breath. From deep in my subconscious came words I learned from CJ Bluestone, Carlee’s dad and Maverick’s search-and-rescue trainer. “Stay calm, no matter what the problem.” I had a problem—a big problem.
My heavy pack continued to pull me under. No matter how much I wriggled and writhed, I couldn’t shrug it loose. I thrashed and my shoes thumped my chest. Then I remembered the ties, but my numb fingers didn’t have the dexterity to undo the knots. The river quickly turned to rapids, more froth, faster moving, more stones, and an increase in the roar of spilling water. Whatever waited for me wouldn’t be gentle, and my efforts to steer toward shore made no headway. I watched a huge log a few hundred yards in front of me rise up and plummet out of sight. Kicking and flailing had little impact on my trajectory. My strength declined. My head filled with a million thoughts, some welcome memories and some regrets, when I realized, I wasn’t going to make it.
