The detectives are met with a wall of silence when they try to find out who was responsible for the brutal attack of an elderly widow in her home on a notorious London estate.
The victim claims her life savings of £10,000 were taken from her spare room, but the team doubts her veracity.
The investigation points towards numerous suspects, including the victim’s son, a man with convictions for robbery and cannabis possession, and another with a history of violence.
