Deep Sleep — Frances Fyfield

When Margaret Carlton, wife of the "Caring Chemist" Pip, dies in her sleep, Helen ignores Bailey's caution to stay out of police investigations. Margaret's apparent good health and relative youth, together with an incomplete police report, arouse Helen's suspicions and her professional ire. Probing into the affairs of a London neighborhood known as Herringbone Parade, Helen uncovers a viper's nest of twisted passion, jealous rage, and lethal addictions. As a sudden crisis rooted in the violent past erupts, a murderer stalks his unwitting prey...and DEEP SLEEP propels us toward its dramatic and startling denouement.
