When she receives a photograph of her art college class, Sister Joan is reminded of her promise to meet her classmates for a 20 year reunion. She is allowed to go, provided she uses the opportunity to advertise for the convent's new retreat offers.
At the meeting in London, Sister Joan learns that two of her classmates are already dead. Her visit to a third's home reveals that he died a few months earlier. As if that weren't enough to make her suspicious, the woman she talked to at the home of the deceased is murdered a few hours after they spoke.
The remaining classmates decide to book a retreat at the convent to continue the reunion. Then Sister Joan receives another copy of the class photo--with a threat in it. Can she find out what is going on before more classmates die?
A Vow of Fidelity was published by St. Martin's Paperbacks and has a 1995 copyright.
Despite the foreignness of the main character (I am not religious so have no experience with nuns and convents), I was comfortable with her perspective and quickly drawn into the story. The characters are interesting and realistic and the entire story is exciting. A good read.
Tense
Past.
POV
Vow of Fidelity is told in third person limited omniscient from the perspective of Sister Joan. Despite careful study, I found no POV breaks. It is very well done and Sister Joan is an interesting character.
Deaths
There were plenty of deaths talked about in the book, but only one is in the present. On page 26, we find out that Sally, the wife of a classmate and a classmate herself, died a few years earlier after a fall from a car park. The car park was known to be dangerous and her death is considered an accident, but there is some question in the minds of the classmates.
Bryan Grimes, another former classmate, was killed in a hit-and-run. We find this out on page 29.
Sister Joan learns of the death of Serge, a third classmate, on page 47. He had died a month earlier of an overdose. But his girlfriend swears he didn't take drugs and was not suicidal.
The death of a gypsy child on page 138 is a reminder of a child who died several years earlier.
There is another death on page 162, but telling you about it would be too much of a spoiler.
Suspects
Sister Joan fears that one of her living classmates is behind the crimes. She focuses her attention there.
Other
There was plenty of back story but it wasn't intrusive.
The book is a fine read on its own, even without knowledge of the several earlier books in the series.
