Katie & Maverick Cozy Mysteries, Book #10

Publisher: Secret Staircase Books
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.
Interview with Mary Seifert
What is your favorite part of the book?
My favorite part of any book is the dénouement – I love mysteries, and it is in my nature to try to ‘solve them’ before I read the final act. I am ecstatic when I score the right answer. I also like writing the ending and hope I give the same element of surprise and satisfaction to readers.
Does your book have a lesson? Moral?
The moral of all my stories is “justice will be served,” but each one has a specific lesson pertinent to that story such as “Honesty is the best policy” in book eleven. Don’t you wonder what that will be about?
Are your characters based off real people or did they all come entirely from your imagination?
So far, only one character is based off a real person and that it my protagonist’s landlady. Ida Clemashevski is the embodiment of all the great things about my mother-in-law. She, too, stood under five feet but had the personality of a giant. In fact, everyone called her the Little General, and it fit. She is no longer with us, so I get to add even more to my character. I hope I honor her memory.
Every other character SO FAR is made up entirely from my imagination.
Of all the characters you have created, which is your favorite and why?
I love Maverick. Although not a person, he is based on our own family pet with additional terrific abilities that I have seen in the remarkable hospice therapy dogs (and their owners) I’ve been blessed to work with for the past fifteen years. Those animals are blessings and have performed way beyond the expectations of a canine companion.
What character in your book are you least likely to get along with?
ZaZa Lavigne was originally a friend of my main character, Katie Wilk, when they began studying mathematical cryptanalysis, but ZaZa was secretly in love with the man who eventually married Katie, and therein lies the crux of her unhappiness and the reason for her mean streak. I don’t like her on the page any more than I would like her in person, but I love imagining her exploits.
What would the main character in your book have to say about you?
I think Katie Wilk would be say she is proud of the way I write about her. She might also say she appreciates my attention to detail, love of research, insight into people, and my creative ways to cause mayhem for her to solve.
Do you want each book to stand on its own, or are you trying to build a body of work with connections between each book?
Although each of the (so far) ten books could be read as a stand-alone, it is definitely a developing story for Katie Wilk. Her life changes so much over the course of the books – and the first books mirror her first ten months in her job as a teacher. New characters are introduced in each story and some of them are recurring characters. Although there are definitely connections among them, and I have recommended reading them in order.
