Yes, it had all the things you need these days – an unreliable narrator (he’s an art expert, but seems to have labelled something a forgery that, erm, wasn’t), class conflict that isn’t, a possible doppleganger (and then the fear of Capgras Syndrome) .
The characters are well-drawn (said narrator is a bit wet, but plausible in his wetness), the dilemmas and uncertainties and willingnesses to overlook inconvenient facts are all hinted and then teased out.
