Le secret des valises noires

I do like the krimi genre but this instalment is a little plodding. It's about a spate of knife murders (achieved via some fun FX) taking place in London and the detective assigned to the case. He soon finds himself mired in a complex little plot involving drug dealing, a conspiracy, siblings and an eccentric with a penchant for collecting sounds. It's murky but not hugely entertaining, at least not until the fun climax in which everything is explained. There are better krimi out there, put it that way.
