PJ Quinn is the pen name of mother and daughter team Pauline Kirk and Jo Summers. Jo challenged her mother to write a crime novel and, somehow, ended up writing it with her. The result is a series of detective novels featuring DI Ambrose and Chalk Heath, set in the late 1950s, a period of great change that seems like an era ago. Foul Play is the first novel, recently followed by Poison Pen,  Close Disharmony, Poetic Justice, and Skull Days. They have now collected some Tales of Murder and mystery in a new collection Night Call and Other Stories.
