Cato was incensed and told Steele: 'You're dead.' Old for his years, Steel was an unsmiling man – grumpy even. He looked after his troops, sometimes at the expense of the higher ranks. He was the Federation rep for the sergeants, and he took his responsibilities seriously. Straight-laced and hard-working, he was prone to the occasional display of human sympathy. Like most of the officers he talked only rarely of his life at home. But Steele had a partner. She was pregnant but miscarried, and he took it hard. Perhaps that was the cause of his grumpiness. Steele had a snarling presence that caused some of his colleagues to question how far he would go if riled. These doubts multiplied when an old lag died in the cells at Sun Hill and the finger of suspicion was pointed at Steele. He was exonerated after it transpired that the victim had died from a heart attack but the episode had made him realise who his friends were – and they were so few as to be considered an endangered species. Sergeant Callum Stone arrived at Sun Hill in August 2007, as a replacement for Sergeant June Ackland. When Stone was sixteen, he left home after his father was accused of rape. Stone's father was an inspector in the police force and was accused of raping probationer Kelly Ryan. Stone believed Ryan's allegation, but his mother chose to believe his father, so Stone asked his mother to choose between them. She chose his father, and Stone felt he had to leave home. He then joined the police force "to punish him". Shortly after Stone's arrival at Sun Hill, he allowed a man to commit suicide in front of him and PC Will Fletcher. Fletcher felt guilty, believing he could have saved the man's life, while Stone believed he had acted appropriately as the man was a violent criminal. Furthermore, when PC Sally Armstrong crashed her car whilst drunk, she went to Stone who arranged an alibi for Sally. With some help from PC Ben Gayle, Sally was able to escape being charged for drink-driving. Stone then used the situation to his advantage, using his power over people like Sally to get them to do things they might not normally do. Stone is badly beaten when he steps into an argument between Clarinda Blake and another man. Questioned by Inspector Smith and Sergeant Masters, Blake tells them that someone was trying to steal her bag, but she does not wish to pursue any complaint. Back at home, Stone finds himself unable to grip his kettle because of his injuries.
