London: 1883 125 Gower Street was once a house of justice, truth and perspicacity. Now madness, murder and scandal lurk in its empty halls. It is rumoured that its owner Sidney Grice London's foremost personal detective has been driven to the brink of despair. But, as with all good stories, we must begin at the beginning. With Sidney Grice journeying to Yorkshire to solve a mysterious death. And with March Middleton, his ward, left to her own devices in a London swarming with danger and vice. Curiosity, as we know, has a dark edge. So when an intriguing letter leads March to the gates of the palatial Saturn Villa, and into the nightmarish world of her long-lost uncle, it could be the beginning of an end, for all.
