Westminster, at the end of the age of empire. And here, two days before Christmas... an extraordinary mystery is about to unfold...
Footprints in the snow, an unfathomable assault in a Turkish bath... Watson is baffled, but Holmes has a growing suspicion that a seemingly fantastical encounter will become a reality.
