Mother Paul is as keen and quick-witted as she is godly, which makes her detective work a perfect match for the sins corrupting the University of Melbourne. As a new warden for the university, the nun-detective takes on the unsolved murder case of student Judith Mornane's sister—who'd disappeared from the dorm a year prior—just as other mysteries start sprouting around campus, such as a drowning that Mother Paul cannot be convinced was an accident. Mother Paul proves herself as one of the more unique crime-solving protagonists with her "unusual personality hidden behind the impersonal garb and demeanor of a religious [person]," and her impressive sleuthing makes for a satisfying read in this mystery from 1960.
