Sweet thing

Summary/Review: "In a red brick house on a tree-lined street, DC homicide detective Alex Blum stares at the bullet-pocked body of Chris Doyle. As he roots around for evidence, he finds an old Polaroid: the decedent, arm in arm with Arthur Holland, Blum's informant from years ago when he worked at the Narcotics branch. But Arthur has been missing for days. Blum's only source: Arthur's girl, Celeste--beautiful, seductive, and tragic--whom he can't get out of his head."--
