You are cordially invited to a murder. A personal ad in the newspaper inviting strangers to participate in an evening of murder mystery fun and games at the home of Letitia Blacklock is an invitation that Miss Jane Marple cannot pass up. A good thing, too, because when the lights are dimmed real gunshots ring out, killing a young boy. Now it??s time for a new, much more serious game of ??whodunit.?
