Diamantmysteriet The Diamond Mystery

The Whodunit Detective Agency #1

Someone is stealing diamonds from the jeweler Muhammed Karat! It looks like the culprit is someone on his staff, but who? Is it Lollo Smith, the recently hired fitness fanatic with a taste for the finer things in life? It surely can’t be Siv Leander, the loyal shop assistant who is now short of money . . .
The police officer in the little town of Valleby is stuck, so he contacts young detectives Lasse and Maja, classmates who run their own detective agency. Will Lasse and Maja be able to use their detective skills to find the thief? As they well know, even a tiny clue is worth its weight in gold.
