My favourite kind of murder mystery, one that involves nuns. This is a rather pedestrian mystery, but it's fun nonetheless. The characters are believable, even the ones that one doesn't particularly like. The police are believable and, most importantly, not complete idiots. There's nothing worse than a murder mystery where one has to 'take over' the investigation because the police are twits. It's not often that that happens in real life, I don't know why it's so ubiquitous in murder mysteries.
While I did say that the mystery itself is rather pedestrian, it also manages to be complex and unpleasant, as all good mysteries that result in murder should be. Perhaps it's only pedestrian because I read far too many books of this sort.
Anyway, it's a fun read and I'll be keeping an eye out for others in the Sister Mary Helen series and by this author (a nun herself) in general.
