This is a murder story and as such, it offers all the features of the classic puzzle mystery. But it is also cosy, with some nice sidetracks. If you're just looking for a dark murder mystery with cold, unsensitive stereotypes, don't watch this film. It keeps you wondering about the solution to the mystery, but it doesn't make you fly sky high when the door bell rings on a dark night. It is well worth watching, but not if you're only looking for a dark murder mystery.
