Cradle

Rachel resorts to sleeping under her desk in response to Sean's possessiveness, but finds a much more comfortable place to rest her head when Janet invites her to stay at her place. Janet prepares to take the next step in her career as sergeant, but a much younger candidate is given the role. Back on the case from earlier in the series - when an elderly wife was found decapitated with her bedridden husband languishing nearby, there are further twists to the tale as the couple's daughter directs Janet to her brother's remains, admitting that she helped to bury him. Is she a witness or a suspect?
