Evening Lake: idyllic, peaceful, with a close-knit community of families who have been coming to this western Massachusetts getaway for decades. And then newcomer Lacey Havnel and her daughter Bea move in. They are nothing like the well-heeled families who populate Evening Lake. Mysterious, rough-around-the edges, they keep to themselves.

Detective Harry Jordan sees his lake home as a respite from solving crimes on the streets of Boston. The Osborne family views their cottage as a way for the family to avoid the distractions of life--especially Wally Osborne, a famous horror writer who appears to need the peace and quiet more than anyone.

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. As is Diz Osborne, the youngest Osborne son who, unbeknownst to any of them, carries a weighty secret about who else he saw rowing on the lake that night.

When it's discovered that Lacey Havnel died not from the explosion but from a knife wound, it's soon clear that a murderer is on the loose. And this murderer is poised to strike again, and again. Told with Elizabeth Adler's inimitable style, illuminating descriptions, and intricate family dynamics, Last to Know is the definition of a page- turner—
