Ever read "The Snowfly" by Joe Heywood? This is a fiction novel about a secret society of fanatical fly fishers on a quest for the mythical "snowfly" hatch, a huge mayfly that only hatches every 7 to 10 years, never on the same river twice. Giant trout, lost manuscripts, secret maps, violence, romance, intrigue... this one has it all! and, it turns out, Hemingway isn't really dead, he's just chasing this hatch...
Decent escapism if you like that sort of thing.
