For me, the classic unreliable (or untrustworthy) narrator is The Murder of Roger Ackroyd by Agatha Christie and if you haven't read Agatha Christie, this is the book that made her famous. In addition to the Goodreads list, I liked Gentlemen & Players by Joanne Harris. I'm not sure everyone would agree that it has an "unreliable" narrator, but the narrator is less than truthful so I would count it.

Thank you, Christina! I was going to ask if there were any librarians in the group but you beat me to it. I have read two of your recommendations and enjoyed them both so I'm looking forward to trying one of the other books you recommended. I, too, loved The Sweetness at the Bottom of the Pie- Flavia rules! Thanks again.
