Moriarty has risen from the grave and engages Holmes and Watson in a chess game across London. There's a star sapphire, a woman and murders. But it is all so boring with an obvious villain and ridiculous plot contrivances.
This is a vast improvement after the mess that were previous books like: 'Heart of the Dragon', 'The Unholy Cause', 'War of the Sons' and 'One Year Gone'. It's not as good as Mercedes Lackey's 'Burning Water' but it is good, Mary-Sue issues aside. Plus the fact Dean is written as a horn dog and it's somehow all about Sam again.
Lizzie slowly and painfully learns things aren't what they seem and what she has always thought and believed isn't true. This is a dark and disturbing tale of desire, hidden desperation and complicity.
