When asked about when it all began, Peter Maxwell would always say that it was at breakfast one day, when his son said, 'It says in the news that bats are giving people colds'. At that point, that was all anyone thought. Nolan was worried about the Count and Bismarck but of course, as everyone would soon know, it was much more than that. What was less obvious was that the pandemic would also restart a killing spree. Old memories rising to the surface, old enmities and slights recalled and suddenly, in masked and socially distanced Leighford, someone is prowling with a hammer raised to create mayhem. The police are run off their feet and tragedy stalks the land, closer to home than anyone thought possible. In a world where death is striking everywhere, how can anyone hope to bring a murderer to book?
