The book of lies, by Brad Meltzer

By the author of the Book of Fate, I love the cover; looking up at a wall of books. This is a literary and historical mystery, based on the story of Cain. When a homeless man is shot, Cal Harper is called to respond and learns that the man is his long-lost father. Together, they start to put together the puzzle pieces of an eighty-year-old mystery involving the creator of Superman. Turns, twists, back roads and surprises from this great writer.
