By Simon Booker (this is an Audible Original, narrated by Imogen Church with a strong cast portraying the characters). PTSD has left former police detective Joe Cassidy (played by Brendan Coyle—Bates on Downton Abbey) with debilitating panic attacks. To get away from the world, he’s set himself up in a remote cottage on Dungeness Beach in Kent, but the world comes to him when he’s contacted by an old friend. Adam Pennyfeather (Joseph Marcell) inherited a wild animal park, and once saved Cassidy’s life when he was almost trampled by an elephant. Adam’s daughter Bella has gone missing, and he wants Cassidy to help find her. As a friend. As someone who owes him.

Cassidy is also on hiatus from his marriage to Katie (Lia Williams), herself a police detective, who’s handling the investigation of Bella’s disappearance. When Bella’s body is found in the elephant house, strung up like a side of meat, Katie is handed her first murder investigation. This creates inevitable tension between the couple, acting in their official and unofficial capacities.

The fault lines in the Pennyfeather family gradually reveal themselves. Adam’s wife is Isabel (Victoria Hamilton), and his younger daughter is Saffron (Rebekah Hinds). She and her husband, pizza entrepreneur Liam O’Mara (Harry Lloyd), tell Cassidy about Isabel’s lifelong loathing of her younger brother Felix, now Adam’s lawyer, and how Isabel preferred her daughters to her son Gabriel. His birth led to serious post-partum psychosis for which she was hospitalized. Fearing for the boy’s safety, Adam put him up for adoption many years before, and has since learned that Gabriel died in a motorcycle accident.

Trying to worm her way into Cassidy’s orbit is a relentless local journalist, an Australian woman named Chrissy McBride. Brigid Lohrey makes this character so annoying that, along with Cassidy, you’ll probably think, “Oh, no, not her again!”

Cassidy believes his wife is seeing someone, was seeing someone while they were married, at least early on, and that their son Luke is the other man’s child. Three DNA samples sent to a Cambridge lab will tell the tale, but is that information he really wants? Booker builds a nice bit of tension around the receipt of these laboratory results, and with Coyle’s solid portrayal, you can appreciate how torn Cassidy is.

The production includes sound effects of the type a foley artist would deploy in a radio play to indicate a closing door, footsteps, and the like. Possibly this is a matter of personal taste, but the sound effects feel redundant and jar me out of the story.

Animal Instinct is a nicely played, complex story and billed as the first book in a series featuring Joe Cassidy. TV writer Booker will find his listeners looking forward to more.
