This isn't a bad 3 stars, but this could have been much better.
It felt like the narrator was very disinterested in the story and the bored performer made the story seem rather boring. It was a good enough story, but it was also a rather predictable twist. So all in all, it barely kept me interested enough to continue listening. This story could have been so much more too, and the descriptions of the police procedures felt... Well, they felt procedural.
I think I would have enjoyed this much much more with a different reader. In future I'll try reading one of Kerry Willinson's books myself.
