Superdetective Blomkwist leeft gevaarlijk (in De Bende van de Witte Roos)
My favourite Astrid Lindgren books (and one of my all-round favourites, for that) were those about Superdetective Blomkwist: Mästerdetektiven Blomkvist, Mästerdetektiven Blomkvist lever farligt and Kalle Blomkvist och Rasmus. Of course, my Swedish being what it is, I've never read these book in the original language, but rather in the praiseworthy translation by Rita Törnqvist-Verschuur. And now my daughters have reached the ripe ages of seven, seven and nine, I'm reading the stories to them.
