“Holmsie” is the kind of cutesy nickname a teenage girl would never have, unless she’s a fictional female character in a YA novel written by a man. Maybe my tolerance for the YA style is just too low, but I found this whodunnit extremely irritating. Unfortunately, I also listened to this as an audiobook, and the voice actor’s affectations made it even more annoying. The characters were unrealistic, the precocious and chatty best friend was grating, and the plot was simplistic and boring. The only positive thing I might say about it is that it may be helpful reading for teens with OCD.
