A long forgotten book conceals a dangerous secret. James Faraday is about to turn eighty and his daughter has organised a gathering of friends and family at Woodford Grange to celebrate the big day. There will be a marquee in the garden, plenty of food and drink, and a huge stack of birthday presents. One particular gift, however, is proving difficult to track down. For Simon Turing, who works in the local bookshop, it is just another order; an out of print book of wartime statistics. It only takes a day or two for him to locate a copy. As soon as the book arrives, however, things start to go awry. The shop is burgled. Simon is knocked off his bike on his way to the Grange. And a worker at the estate suffers a fatal accident. Is it just a run of bad luck or are more sinister forces at work? Simon is about to find out.
