Kalle Blomkvist, is only thirteen years old, but already a very skillful detective.
A young amateur detective who likes to compare himself to slightly more famous detectives such as Hercule Poirot and Lord Peter Wimsey. He enjoys lying beneath the pear-tree in the garden imagining himself presenting lectures in criminology to a fictitious but admiring audience.
The hunt for the criminals always ends well but once in a while it gets seriously scary. The big world, with all its gangsters, is perhaps sometimes too dangerous for a teenage master detective.
Age 9+
"This is the first of three or so books in the series, and it's a pretty good little kids detective story. Kids solve the case of a jewel heist while playing in their small town. A quaint 50's feel, and some charming quirks in the translation"
