The Erasers is a combination detective story and Greek tragedy, about a murder investigation in which the victim, unbeknownst to (almost) anyone, is not really dead.
It’s also about multiple perceptions of the same events, all of them perfectly reasonable and all of them wrong.
And it’s about the inevitablility of fate, which despite your best efforts can lead you to an unimaginable deed (cf. Oedipus).
Highly recommended!
