The Chaplain of Blackburne House

Jennifer McCreavy has just accepted a position as chaplain, mistress of a girls' dorm called Blackburne House. She has also embarked on an undercover mission. Her half-sister Cathy Foxcroft was a second-year student at the school. The previous April she was found hanged in a dormitory stairwell, presumed a suicide. That was totally out of character; Cathy liked school and had no history of depression or self-harm.
