Dead Man Talking by Roddy Doyle
I didn’t really figure this one out — a novella, if that, about how a big mistake or betrayal you commit might stay with you for the rest of your life — the premise being that his friend Joe dies, he attends the wake with his wife Sarah, and Jose sits up and talks to him (only him) — we’re never sure if it’s the narrator or Joe who has died but either way he is forced to stop pretending to himself that he slept with Joe’s wife and Joe knew. The bottom line, I guess, is that he has to stop deluding himself. Because of death. Cheery Irish stuff.
