A former investigative reporter, Sister Agatha has more than her fair share of spiritual challenges as an extern, a nun responsible for her cloistered order's dealings with the outside world. Still, she's instantly intrigued when the archbishop requests she discreetly investigate the odd disappearances of valuable religious folk art from The Retreat, a former New Mexico monastery-turned-upscale-inn. But soon Sister Agatha is entangled in one unearthly puzzle that includes an art expert who's vanished without a trace, a truly strange flock of out-there suspects, and an unnerving apparition no amount of rationality can explain. She'll have to bring all her worldly instincts and savvy to heading off a disastrous scandal--as well as a sheriff more interested in political glory than finding the truth. And between strange clues and plenty of unexpected motives, Sister Agatha will need plenty of spiritual intervention and heaven-sent cunning to bring one devilish murderer to book
