Forged in the crucible of World War II, Oak Ridge, Tennessee, was a top-secret military installation—the linchpin of the Manhattan Project. Brilliant careers were born and dark secrets buried in the desperate race to build the Bomb. Those secrets begin to emerge when the body of a renowned physicist is discovered facedown in a frozen swimming pool.

Forensic anthropologist Bill Brockton, founder of the Body Farm, is shocked when an autopsy reveals the cause of Dr. Leonard Novak's death: a deadly radioactive pellet inside the elderly scientist's body. Who would commit such a horrific crime? Is it related to Novak's role in creating America's deadliest weapon? The answers may lie with the victim's aging ex-wife, Beatrice, a captivating yet utterly unreliable storyteller. Careening between history and fantasy, dementia and lucidity, Beatrice draws Brockton into a maze of memories, leading him to darker truths than he could have imagined.
