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.
