With no alibi, Hollis is the prime suspect for Doreen's murder, and he is suspended from duty. While CID try to trace the victim's long lost daughter, with little to no information, Stamp and Klein try to find an alibi for Hollis. They interview a witness outside of Doreen's house, who claims that he saw Hollis hanging around the property more than hour before he stated that he arrived. With the evidence mounting, Stamp and Klein's only hope of clearing Hollis' name lies with a tom, who provides a statement claiming that Hollis was with her at the time of Doreen's death. When a scam involving her 'long-lost daughter' comes to light, Hollis is cleared and CID attempt to track the imposter down.
