THE SECRET THAT KILLED YOU

In Hadden’s second series thriller, a private investigator risks his new family to help a desperate woman find answers.

P.I. Ike Rossi’s new client is Amelia Garcia, a retired U.S. Air Force drone pilot who now runs a remotely operated deep-water vehicle for Falzone Energy, owned by Ike’s friend Shannon Falzone. Amelia’s hobby is collecting artifacts from the ocean floor, but her latest find, a strongbox emblazoned with a Nazi eagle, quickly puts her in danger. She mentioned it to her Uncle Billy, and soon afterward, he and his wife, Bessie, were found dead. Billy’s contact at the U.S. Department of Justice was killed in a car wreck around the same time. The deaths get the FBI interested in the case, and Ike gets involved as well after a panicked Shannon asks for his help. As it turns out, one of the FBI agents is Mia Russo—Ike’s old flame, whom he considers to be the one who got away. Shannon convinces Ike to fly with her to Kiawah Island, South Carolina, to meet with Amelia. Ike is still seeking answers to his own parents’ murders 23 years ago, but he agrees to help. It soon becomes clear that someone powerful is after whatever’s in the strongbox. With the help of retiree Frank McNally, an ex–World War II codebreaker with his own secrets, Ike and Amelia must solve the mystery before it’s too late. Hadden begins with a novel concept: a dogged and skilled detective who’s unable to solve the biggest mystery of his life. Although Ike makes significant headway on that front this time out, he still ends up with more questions than answers. Most of the colorful characters from Hadden’s first series installment, The Victim of the System (2018), return, but he also develops engaging new characters, including Amelia and tech whiz Dominic Massaro. Ike and Amelia often clash over the direction of their investigation, wasting precious time; their delays also allow those chasing them to close in, making for an effectively suspenseful narrative that proceeds at a brisk pace.

A conflicted investigator successfully follows his conscience in this well-constructed mystery.
