Webb and Banksy investigate a suspicious house fire, and Webb is surprised when he discovers the homeowner is an old informant of his. The prime suspect is the victim's landlord, who worked with the victim in the past. Events take a bizarre twist when, during forensic searches, Olosunje finds human remains in the basement. The victim is identified as a contractor who went missing in the 1970s. The big question is; who did it? Webb is drawn to the landlord's solicitor Naomi Woods, but he is left embarrassed when Banksy reveals she is his wife.
