Illona Haus announced her arrival in the world of crime fiction in the spring of 2005 with her acclaimed debut Blue Mercy - a gritty, edge-of-your-seat psychological-thriller featuring tough and savvy Homicide detective Kay Delaney. Set in Baltimore, Maryland, Haus's novels are populated with compelling characters, made genuine by her personal connections and experience with the city's Homicide Unit over many years.

It is Haus's bold and unique voice, her unflinching eye for detail, and her cutting-edge research, that make the Kay Delaney series a world that is both intensely authentic and horrifyingly dark.
