This is book number 3 in the A Locard Institute Thriller series.


With a duo of complex female protagonists, breakneck plotting, and authenticity informed by her career as a crime scene analyst, New York Times bestselling author Lisa Black’s Locard Institute Thrillers land her in the same league as Tess Gerritsen, Patricia Cornwell, and Kathy Reichs.

Now forensic experts Ellie Carr and Rachael Davies are called to a billionaire’s private compound on Florida’s Gulf Coast to investigate a tragic death amid a dangerous storm of power, deception, and conspiracy…

For software pioneer Martin Post, the third richest man in America, his private compound on the Florida coast is a sunny no-man’s-land separating his family from the rest of the world. Now, expert forensic analysts Ellie Carr and Rachael Davies of the renowned Locard Institute have been summoned to its dark side.

Martin’s pregnant daughter, Ashley, had ventured on a day trip in her motorboat into the Gulf, only to wash up dead on a nearby shore. Although the local coroner determined her death was an accident, Ellie and Rachael soon confirm Martin’s gravest fear: His daughter was murdered. Was it a kidnapping gone wrong? Or something even more brutal? Ashley and her husband, Greg, had been working with Martin on a revolutionary new defense initiative for the US military – could espionage have played a part in her death?  Martin believes Greg is behind the murder, and the spoiled charmer does set off Rachel’s deception radar.  If the widower didn’t kill Ashley himself, why isn’t he more upset that she’s dead?

Drawn into the Posts’ increasingly dangerous family dynamic, Ellie and Rachael must work hard and fast to discover what secrets are buried at the heart of the crime. Because the churning waters of the Gulf are getting rougher. And soon, Ellie and Rachael themselves will be in danger of getting crushed in their depths.

Praise For…

Praise for the Locard Institute Thrillers:
“Lisa Black writes from her own experience as a forensic scientist, instilling What Harms You with the perfect blend of technical accuracy and polished storytelling. Kathy Reichs and Jeff Lindsay have claimed this turf as their own for years, but Black is every bit their equal.” —BookTrib on What Harms You

“The action is non-stop and the descriptions of crime scene analysis are fascinating and gruesome. With the authentic details and Ellie and Rachael working together, this could be only the beginning of a welcome series.” —Akron Beacon Journal on What Harms You

What Harms You is a terrific, CSI procedural that takes a thoughtful, even-handed view of life and crime-fighting in the 21st century, balancing hot-button topics with common sense approaches.”  —Criminal Element on What Harms You
“A brilliant idea and the ultimate locked-mansion mystery – a serial killer possibly on the loose at an elite CSI school – fully realized into a cinematic and riveting page-turner. The oh-so-knowledgeable Lisa Black immerses us in the fascinating science, the deadly secrets, the authentic details, and the personal danger. Fans of Tess Gerritsen and Kathy Reichs will especially be drawn to this compelling and fast-paced novel.” —Hank Phillippi Ryan, USA Today bestselling author on What Harms You
“Lisa Black’s return to the Locard Institute in What Harms You is a bona fide page-turner that kept me on the edge of my seat. What a great team Dr. Ellie Carr and Dr. Rachel Davies make. Black knocked it out of the park. The Locard’s in good hands, and so are we.” Tracy Clark, award-winning author of the Cass Raines and Det. Harriet Foster series on What Harms You

Black combines spot-on forensic detail with empathetic characters I can't wait to see more of--this series tops my list of new favorites." —Deborah Crombie, New York Times bestselling author Duncan Kincaid/Gemma James Novels on What Harms You
