Cameron Clewe and Jane Hunter, lovers of all things bookish, are slowly cataloguing Cam's private collection of first edition books acquired from the deceased patriarch of the wealthy Stewart family. When Jane finds a note from Kimberly Stewart Ward, one of the daughters of the Stewart patriarch-who supposedly committed suicide-she discovers someone was actually targeting her with the intention of killing her. Jane and Cam decide to look into the supposedly closed case, but their investigation becomes urgent when another member of the Stewart family is found dead from a drug overdose. The victim's friends claim he'd been clean and sober for years and refuse to accept the cause of death. Believing both cases to be connected, Jane and Cam resolve to solve them before any other direct heirs of the family are targeted.
