Something doesn't add up about Archie and Pye ... After a disastrous day at work, disillusioned junior PR executive Tom Winscombe finds himself sharing a train carriage and a dodgy Merlot with George Burgess, biographer of the Vavasor twins, mathematicians Archimedes and Pythagoras, who both died in curious circumstances a decade ago. Burgess himself will die tonight in an equally odd manner, leaving Tom with a locked case and a lot of unanswered questions. Join Tom and a cast of disreputable and downright dangerous characters in this witty thriller set in a murky world of murder, mystery and complex equations, involving internet conspiracy theorists, hedge fund managers, the Belarusian mafia and a cat called µ.
