After the break-up of her second marriage Brenda Casebrook was left with her two sons, Len and Adam, now aged 22 and 18. Adam was the closest and she saw him as dependent upon her. Three years before I saw her, Adam had gone out with his friends for a drink at the pub. He was late returning and Brenda was alarmed when after midnight there came a knock at her door. A policeman and woman asked if they could come in. They told her that Adam had been stabbed to death in a fight.
