It's a quiet winter Sunday morning in the seaside town of Seaborne and the local museum is about to carry out a disaster exercise to test the emergency services' response in the eventuality of a full-scale catastrophe. Lured by the promise of overtime rates, several members of staff are lying around in the cold with imaginary injuries or 'playing dead'. Unfortunately, one man remains motionless - he's well and truly lifeless. For the museum's PR expert Deborah, there's ather shock in store as the dead man's identity is revealed. But how did he die and, more importantly for Deborah's peace of mind, what was his purpose for visiting her place of work?
