On 13th March 2011 a distressed 999 call comes in from Julie Dixon, partner of well-loved carpenter David Twigg. Julie is clearly in a state of shock as she tries to describe the attack by masked men and that her partner is locked in a storeroom that has been set on fire.

Although she has suffered burns she manages to escape to raise the alarm. The fire brigade arrive but unfortunately they can't save David. It's very unusual for a murder to happen in the sleepy Lincolnshire village of Burgh Le Marsh.

Friends and family rally ‘round to support Julie who is in a traumatised state. Nobody can understand why anyone would want to murder David. The local community are terrified, and police are under enormous pressure to catch the culprits quickly. Julie helps police with their enquiries and describes the attackers and the events that took place in detail.

As they start their enquiries the police discover that David's business was in serious debt. Could this be a factor in his murder? They start to pursue different leads: did he owe someone money? Was it a robbery gone wrong? Or a neighbour with a grudge?

But their investigation stalls and so they begin to relook at the case again, starting at the beginning with the person who made the 999 call – his partner Julie. This sends the investigation into an unexpected and shocking direction.
