The Face in the Mirror Mystery, The Woman Scorned Mystery, and The Fugitive Priest Mystery. Father Philip Prestwick, who provides comic relief, is a social-climbing assistant to the Archbishop. Father Phil just happens to drop in before every meal. Mrs Marie Gillespie is both the parish secretary and the housekeeper of the Rectory (in which the parish priest lives). The show's format in effect creates a pseudo-family: Father Dowling and his elderly housekeeper, Marie, behave like an old married couple, with Father Dowling acting like the regular father in a conventional family (somewhat aided by his identification in the minds of the audience with Mr Cunningham, the character Bosley played on the TV series Happy Days). Both of them treat Sister Stephanie as though she's their daughter. The humour largely emerges from the intrusions into this "family circle" by Father Phil, who, like an unwanted relation, disrupts the cosy informality of the household. The humour develops from the fact that Phil, in his innocence, never realises that his presence is largely an irritant to the others. A further recurring character is a female Chicago police officer, Detective Sergeant Clancy (Regina Krueger), who is Father Dowling's friend and principal police contact in the first two seasons. In season 3 Dick O'Neill replaces her in some episodes, as Lieutenant Foster, an old friend of Frank's in the police, and a devout Catholic, who Frank browbeats into doing him occasional favours during the investigations. The mysteries usually begin with a mysterious visitor to St Michael's church, or to the parish Rectory next door where Father Dowling lives. In the first season, Sister Steve lives in a convent with the other nuns in her Order ("The Pretty Baby Mystery"); but in the second season she takes her meals at the Rectory, and when her brother is accused of murder (in the episode "The Sanctuary Mystery") he's shown sheltering in her bedroom at the Rectory. Throughout all three seasons she's also a chauffeur for Father Dowling, who doesn't drive. Because she's a car enthusiast, and reformed car thief, she handles the parish station wagon like a professional stuntman. Between attending to parish secretarial and housekeeping duties, Marie takes phone messages for the duo while they're out travelling all over the city investigating their latest case. Meanwhile, Fr. Phil pops in and out of the Rectory, almost always at mealtimes. Marie and Father Phil provide light
