After a lifetime of plotting each other's demise, orphan twins Lorelli and Ovid Thornthwaite have reached an uneasy truce. No longer trying to kill each other, they are living a quieter life in the remains of the burnt-out Thornthwaite Manor. It's not long, though, before some peculiar 'near accidents' begin to take place and the twins begin to wonder - is someone else trying to bump them off?

Could it be the oddball builder Dragos, or Jean-Paul Suricates, the twins' triple Michelin-starred chef? What would old Tom the gardener have to gain from the deaths of Lorelli and Ovid? Or stinking rich Uncle Harry Morgan, who claims to be the twins' long-lost uncle on their mother's side? As the number of near fatal 'accidents' ramp up, it becomes clear that there are some dreadful forces at work - but just who is behind the Thornthwaite betrayal?
