Spoiler-Free Synopsis

In a shadowy Parisian gambling salon, the Duke de Saligny steps into a private card-room while police guard every doorway and the windows remain barred. Within minutes, a scream pierces the salon. When Henri Bencolin forces the door open, the Duke is found decapitated—yet no other soul is present and no weapon remains in the room.
