It goes weird but comes together at the end. I keep writing about characters who fall into a maze and have to work things out. The puzzle is the journey and it doesn't always end with the story. The narrator, a character named Ellerslie Penrose, becomes the person who solves the puzzle. He isn't a detective, but he's driven to investigate matters, to redeem himself.
Shirker is a mystery about time and memories, and different versions of reality.
Like Pack of Lies and Heaven were, I guess - people who construct and dismantle illusions. Your second novel Heaven has been turned into a film which is out very soon. The film's attracted a cult following, but I haven't seen it yet, no. I feel like I've already seen one version. It's romantic to pursue a different view of the world - especially if it's shocking or unlawful.
