NO BAD DEED

A good Samaritan incurs a psychopath’s wrath in this debut thriller.

Veterinarian Cassie Larkin is heading home after a 12-hour shift when someone darts in front of her car, causing her to dump her energy drink. As she pulls over to mop up the mess, her headlights illuminate a couple having a physical altercation. Cassie calls 911, but before help arrives, the man tosses the woman down an embankment. Ignoring the dispatcher’s instructions, Cassie exits the vehicle and intervenes, preventing the now-unconscious woman’s murder. With sirens wailing in the distance, the man warns Cassie: “Let her die, and I’ll let you live.” He then scrambles back to the road and flees in Cassie’s van. Using mug shots, Cassie identifies the thief and would-be killer as Carver Sweet, who is wanted for poisoning his wife. The Santa Rosa police assure Cassie of her safety, but the next evening, her husband, Sam, vanishes while trick-or-treating with their 6-year-old daughter, Audrey. Hours later, he sends texts apologizing and confessing to an affair, but although it’s true that Sam and Cassie have been fighting, she suspects foul play—particularly given the previous night’s events. Cassie files a report with the cops, but they dismiss her concerns, leaving Cassie to investigate on her own. After a convoluted start, Chavez embarks on a paranoia-fueled thrill ride, escalating the stakes while exploiting readers’ darkest domestic fears. The far-fetched plot lacks cohesion and relies too heavily on coincidence to be fully satisfying, but the reader will be invested in learning the Larkin family’s fate through to the too-pat conclusion.

Chavez delivers a fraught if flawed page-turner that attempts too many twists.
