Mark, a detective in charge of Joanne Hodson's murder investigation, questions her husband Stephen Hodson about his whereabouts on the night of her murder. Stephen claims he was in bed with his wife, but Mark informs him that the time of death was actually the night before at 9pm according to forensic evidence. When Stephen denies this is possible, Mark has him taken into custody for further questioning, as they have evidence implicating him in Joanne's death.
