The Route of the Blue Carbuncle

The blue carbuncle had quite a journey. Before it even arrived in the action of the story, the piece of crystallized charcoal was the object of "two murders, a vitriol-throwing, a suicide, and several robberies."

But once it's in London and disappears from the Countess of Morcar's possession, where does it go? Gavin Brend takes us on the wild journey. It's just a Trifle.
