I saw a film a good 5/6 years ago, about an opera singing neighbour and piano player whose who's neighbours (five boys) suspect him of killing his wife, they investigate by going in to his house... it's a great film and I can't figure out the name of it?
I also remember he puts the body in the freezer?

Please help me find the name of it!
Thanks
