Mystery 101 is an American/Canadian series of mystery TV movies created by Robin Bernheim and Lee Goldberg.^[1] It stars Jill Wagner, Kristoffer Polaha^[2] and Robin Thomas. The series airs on the Hallmark Movies & Mysteries channel in the United States and on the W Network in Canada.

Amy Winslow is a professor of English literature at Elmstead College, in the (fictional) small coastal town of Garrison, Washington. She specializes in mystery and crime fiction. In the first film, a case involving a student at Elmstead has Amy consulting for Travis Burke, a "big city" police detective who has recently moved to Garrison. Amy's widower father, Graham Winslow, is the author of a bestselling series of detective novels and often helps Amy when she's in a pinch. As crimes unfold in the area, Amy inserts herself into Burke's investigations, often against his wishes; the two develop an increasingly strong friendship, eventually moving to first kiss at the end of the sixth film. In the first three films, Burke is also assisted by Claire Tate, a rookie detective who is the daughter of Garrison's police chief. Amy's teaching assistant, Bud, often helps her on cases with research and other tasks.
