Ava Bonney of Birmingham, England, is not your typical sleuth, and she’s one readers of Marie Tierney’s debut mystery, Deadly Animals, will long remember. Living in a sparse apartment with her younger sister and selfish mother, 14-year-old Ava makes her own entertainment. Bones fascinate her—“We are our bones,” she says. To further her scientific studies, she has created a secret “body farm” to study the anatomy of decomposing roadkill that she finds. A former biology teacher who grew up in Birmingham herself, Tierney sets the book in the early 1980s of her youth, writing with the analytic precision of a scientist and the literary aplomb of a gifted storyteller.
During a morning outing to her farm, Ava discovers the body of 14-year-old local bully Mickey Grant and, soon after, the missing, now murdered 6-year-old Bryan Shelton. Ava quickly acts to preserve valuable evidence in danger of disappearing. Fearing the police won’t take her seriously, she pretends to be an adult while calling in Mickey’s murder, and enlists her best friend, John, to call about Bryan. “Their secret was gargantuan,” Ava and John realize. “It was scary and exciting, an adventure—but also a horror story.”
A serial killer is on the loose, and Ava begins a surreptitious partnership with Detective Seth Delahaye—who recognizes her genius—to track down the murderer. Ava and Delahaye’s initial cat-and-mouse communications burgeon into mutual trust and respect, forming the empowering heart of the novel. “Ava was custodian of the dead,” Tierney writes, “this she understood. The idea of hurting an animal, by accident or on purpose, was anathema to her.” As Ava stumbles across murdered bodies and tortured animal corpses, she has an “awful epiphany: this killer was just herself turned inside out: her fatal inversion.”
This noteworthy debut is a fast-paced, brilliantly plotted mystery, filled with short chapters and crisp prose. Gory—but never gratuitous—details of dead animals and humans abound, but all are in service of the plot, as well as Ava’s scientific interests and investigation. As the book progresses, the stakes become higher and danger creeps closer to Ava and John, leading to a dramatic conclusion. With Deadly Animals, Tierney has created an exceptional heroine who demands a sequel.
