Mark is questioning Stephen Hodson, the prime suspect in his wife Joanne's murder investigation. Mark informs Stephen that the evidence shows Joanne died the night before at 9pm, contrary to Stephen's claim that he was in bed with her at 10:15pm on the night in question. As Stephen cannot explain how Joanne's body was found in the woods at the same time he said they were together, and firm forensic evidence implicates Stephen, Mark has him taken into police custody for further questioning.
