Demary Jones's Confidential Research and Inquiry specializes in genealogy and historical research, not murder. But when a sniper opens fire in her office, killing a clientwho wants her to tap his phones, and leaving Demary with a head wound, she's very determined to accept the widow's generous offer to track down a killer.
Soon there's a string of connected murders that put Demary's investigative skills to the test: the body of a warehouse worker; a young man found floating in a bathtub; another, the victim of a "fall." As she cleverly uncovers both a drug trafficking network and some shocking facts about the people closest to her, she also comes face to face with a conspiracy of killers desperate to make Demary's life story a closed book.
