Tiril and Oliver are at the police station to attend an auction of lost and unclaimed items, where Tiril buys an old suitcase and Oliver buys a small brass cannon figurine. Something about the unusual cannon makes them curious. Who did it belong to? And why has no one come to claim it? With clever thinking and patience, Detective Agency No. 2 sets out to solve the mystery.

Jørn Lier Horst & Hans Jørgen Sandnes’ Detective Agency No. 2 series is crime fiction for the youngest – clever, engaging, and full of thrills!
