But the police aren't the only people looking for Sean. Can Mason discover the link between Sean's disappearance and the dead senator's? Can he find Sean before the cabal? Will the conspiracy be unmasked? Will justice finally be served?Seen Sean? is the second book in the Mason & Penfield Mysteries.
