Evening Lake: idyllic, peaceful, with a close-knit community of families who have been coming to this western Massachusetts getaway for decades. Detective Harry Jordan sees his lake home as a respite from solving crimes on the streets of Boston. One night, Harry Jordan is walking the lake when the night is rocked by an explosion: the Havnel house is engulfed in a conflagration and young Bea Havnel is seen fleeing, hair on fire, plunging into the lake. She survives but her mother does not, and Harry is pulled into the investigation.
