Finished this earlier this week. Thanks for the recommendation @wonton.
Quite a strange little novel – I found the main character really interesting at the beginning, but went off him a bit when it got to the point where he was a famous photographer, though I do often find that describing fictional works of art in fiction quite difficult and often they don’t quite ring true. I liked the way it split to the second act, as you call it.
It reminded me in some way of the film The Killing Of The Sacred Deer – everything is a little bit ‘off’ and understanding is just out of reach, but then there are some moments of clarity that leap out… I really liked the bit in the courtroom where the lawyer just takes the police officer to bits, to the point where I thought that whole thing was going to be the reason he had set up the case.
In summary - I enjoyed it. I’m not sure it ‘works’ 100% but I think its worth celebrating an attempt to create something that doesn’t fit expectations.
