In the quiet corridors of a seaside care home, on an ordinary weekday afternoon, a 92-year-old man sat confused in his wheelchair, gripping a butter knife he'd been using to eat his lunch. Within minutes, two police officers would arrive at his door after being alerted that it was vital for them to attend the scene quickly, as someone’s life had been threatened…

Olivia was woken up around 3:30 am on December 30, 1999, by the sound of something crashing to the ground. She prodded her husband awake. She was sure that somebody was in the house. She jumped out of bed and ran to lock the bedroom door. George, her husband, was wide awake now. He got up, put on his boots, before manoeuvring past his wife and making his way down the dark staircase. When he reached the bottom floor, he felt the cold December air coming in through a broken kitchen window. Amongst the shattered glass was a broken piece of a statue of St Michael that was usually kept in the conservatory. He went to another room and smelt cigarette smoke in the air. Someone was in the house. He decided to return to his wife upstairs, but by this time she made her way to the living room, which adjoined to their bedroom. She was calling for help. They could hear someone downstairs walking on the broken glass. What was going to happen to them, and who exactly was in their house?…
