Bored to Death (2009)

Jonathan's amateur private-detective work regularly pulls his two friends into situations they are ill-equipped to manage. Bored to Death supplies the New York companionship and comic self-invention that make Charles, Oliver and Mabel enjoyable beyond any particular clue. Choose it for an older, offbeat trio whose affection survives a lot of foolish behaviour. The cases are looser and the humour more adult than a cosy puzzle, with three seasons of wandering into trouble.
