The Fall Guy was just too slow. That is the basic reason that it was not for me. I'm not sure selling it as a "Taut psychological thriller " is doing it any favours because it is not taut nor is it really a thriller. It is more character study and yes some lovely literary writing the author has got going on here but although I love some literary stuff I need to have at least a sense that something might happen soon. Or at least a little tension.
I think it would have worked better from multiple viewpoints. We only get the one and that one is vaguely monotonous at times and seriously if I wanted to read a cookbook I'd get a cookbook. The plot kind of meanders along until quite late then suddenly things pick up but by then I was genuinely past caring. If we had heard from the other characters in the drama - and that is what this is a character drama- it might have added layers beyond lots of beautiful words tagged together to tell a rather long winded (yes it is only a short novel but trust me it feels long winded) story. For me the ending was lazy too.
Look it's not terrible, certainly James Lasdun has excellent writing skill but I was bored. The only reason I finished it was because it was short and I had an occasional eye on "maybe this is going to have a kick ass finale that will make all this worthwhile". Sadly that did not happen. At least not in my opinion.
I think The Fall Guy and I are not compatible. We had a brief interlude in time but the relationship really wasn't going anywhere.
If you like the Donna Tartt school of novels you will likely love this to be fair. I was the wrong audience and I'm probably missing the nuances of what the author was trying to achieve here, hey it happens.
