Another serviceable cozy murder mystery. This time, set at Christopher's boarding school -- it's the last day of term, and while doing a huge favor for Marmalade (a vastly more interesting character), his school bully slash new friend, Christopher discovers their headmaster murdered in his office.
Luckily, his grandfather, Lord Edgington, is on site with all the other families for the end-of-term festivities (along with Christopher's mom, as well as Marmalade's crappy rich ex-criminal dad). Even more luckily, the police Inspector Blunt, despite his obvious antipathy towards Lord Edgington, has apparently just totally given up on inspecting and pretty much immediately lets Lord Edgington do his job for him. Which is whatever, I guess. I don't really get why the author made Blunt so antagonistic, which makes his behavior here seem strange; if Blunt liked or admired Lord Edgington, him allowing an old man and a 16-year-old boy to run free around the crime scene would make more sense.
Speaking of the latter, I'm trying to be generous because I know chubby teenage dweebs don't have the abilities of adults, but as someone else noted in a review, it can get a bit tiresome when the narrator, our perspective character, is so incompetent and lacking in confidence. Other reviews indicate that there are many people who do enjoy Christopher's point of view, so perhaps I'm just old and crotchety. It seems like a goal of the books overall will be to make Christopher not just an investigator like his grandfather, but also a Man, so perhaps if I give him time and a few more books, he'll get more interesting.
