In a 1960s convent, Kristen, a first-year nun, and her teacher, Sister Inez, stumble over a dead body in the basement of the motherhouse late one night. The woman is dressed like a nun, but no one knows her. The police are called and begin their investigation, but Sister Inez, ever the busybody, insists that she and Kristen will solve the murder. Complicating everything is Kristen's attraction to the young detective assigned to the case. Their investigation is harmless enough until Kristen gets a threatening letter from the murderer telling her to stop, and she begins to worry for her life. Was it another nun in the motherhouse who committed the crime? Will they solve the murder? Will her infatuation for the detective ruin her vocation? Kristen will solve three cases in this first book of the Who Nun It? Mystery Series.
