Jane Haddam (1951-2019) was an American author of mysteries. Born Orania Papazoglou, she worked as a college professor and magazine editor before publishing her Edgar Award-nominated first novel, Sweet, Savage Death, in 1984. This mystery introduced Patience McKenna, a sleuthing scribe who would go on to appear in four more books, including Wicked, Loving Murder (1985) and Rich, Radiant Slaughter (1988).

Not a Creature Was Stirring (1990) introduced Haddam's best-known character, former FBI agent Gregor Demarkian. The series spans more than twenty novels, many of them holiday-themed, including Murder Superior (1993), Fountain of Death (1995), and Wanting Sheila Dead (2005). Haddam's later novels include Blood in the Water (2012) and Hearts of Sand (2013).
