I really enjoyed this book. It is a kind of steampunk Victoriana with a magical atmosphere. We are introduced to a clerk who works away on the telegraph in the bowels of Whitehall living a spartan life in a tiny flat. Strange things start to happen as a mysterious watch is left in his flat. The plot twists and turns and leads us to the mysterious watchmaker of Filigree Street who is of Japanese origin and makes some amazing clockwork toys. Various characters are introduced and their strange stories collide in a dramatic finale.
There were points where I virtually lost the thread and I couldn’t quite work out what exactly had happened or why. It would probably repay a re-reading.
