The Good Suicides by Antonio Hill

Young, free and ... dead

Senior staff at Alemany Cosmetics company come home with a secret after a team-building course in a remote country house. Now, they are committing suicide, one by one. Soon, they may all be dead. Each has received a photo from an anonymous source of three dogs hanging dead from a tree near the house.

Deciphering the personalities of these high-earning executives and their power structure, Inspector Salgado has his own way of making them speak. But Barcelona is now freezing cold and the city is hunkering against an unusually cold spell. Can Salgado break the ice before it's too late?

Well it all started so well, a girl is pushed/jumped infront of a train and then it went so wishy washy and I was reading it for the sake of reading it and not because I wan't to know how it ends.  I hate not finishing a book infact this is only the second book i've not finished.  Maybe i'll revisit it one day but not in the near future :-(
