Publisher's Synopsis
In an ancient remote mansion nestles the infamous Black Dudley Dagger - a jewel-encrusted Italian blade, weapon in a centuries-old murder. As house-party guests merrily recreate the traditional ceremony of the dagger, passing it from person to person in pitch darkness, death strikes once more when Colonel Gordon Coombe is felled by an apparent heart attack. But pathologist Dr George Abbershaw suspects foul play. And Meggie Oliphant swears that when the dagger was pushed into her hand, it was stained with blood. What really happened to the Colonel? And just who is the mysterious guest Mr Albert Campion?
