The Holiday Pet Sleuth Mysteries represent Marlene Bierworth’s entry into cozy mystery territory. The sixteen books, published in 2022 and 2023, feature dogs and cats helping their owners solve lighthearted mysteries tied to specific holidays. Halloween Hi-Jinx, Christmas CAT-astrophe, and Easter Egg Scramble are typical of the playful tone.
The series stands out in Bierworth’s catalog as her primary non-romance offering, combining pet stories with holiday themes and gentle mystery plots.
