No cozy mystery would be complete without a trusty companion or two. Sometimes these come in the form of a team of quirky relatives, like the Calendar Crew of meddling aunties in Mia P. Manansala’s Tita Rosie’s Kitchen Mysteries or even a supernatural frenemy, as in Olivia Blacke’s Ruby and Cordelia Mysteries.
In my Deep Dish series, though, the key role of sounding board/emotional supporter/cuddler-in-chief belongs to Butterball, an orange tabby with the heart of a lion and the stomach of a chonk-monster. While Butterball isn’t exactly Sherlock Holmes (he is, after all, just a cat), he has a way of revealing clues that my human sleuth, Delilah O’Leary, might otherwise overlook.
In my latest book, At Death’s Dough, the roles are reversed—this time it’s Butterball who lands in hot water, and it’s Delilah’s turn to rescue him. Writing the story got me thinking about just how much pets bring to a cozy mystery.
Furry (and scaly and feathered) companions have become fixtures in cozy mysteries not just because they’re cute, but because they serve important narrative and dramatic functions. They provide a wholesome counterbalance to the violence at the heart of these stories. They can also ground the sleuth in everyday life, showing a softer, more vulnerable side of a character like Delilah, whose personality can be prickly. Their instincts, antics, and sheer existence can move the plot forward in organic ways. At the same time, they reinforce one of the central pillars of the cozy mystery genre: even in the dark shadow of crime, comfort is close at hand.
Butterball isn’t the only four-legged sidekick kicking butt in the world of cozies. From loyal hounds to opinionated cats, these companions prove that crime-solving can be more fun with a furry gumshoe (gum-paw?) on the case.
