It ends at midnight

It's New Year's Eve and the stage is set for a lavish party in one of Edinburgh's best postcodes. It's a moment for old friends to set the past to rights - and move on. The night sky is alive with fireworks and the champagne is flowing. But the celebration fails to materialise. Because someone at this party is going to die tonight. Midnight approaches and the countdown begins - but it seems one of the guests doesn't want a resolution. They want revenge.
