Louise’s theory about the stalker's identity is fuelled when Syd lets it slip that Mack had invited women to stay at Mill Cottage while she and Ray were away. She is horrified to think of strangers in her bed and sees this as confirmation that he is the stalker. Ray comes home to find Louise hysterically stripping their bed linen. Ray is incensed when he hears what Mack has done and insists they must call the police. There is bad news for Zak when Shadrach turns up out of the blue at the Dinlges. He greets Zak warmly, but it is obvious something is wrong. (thetvdb.com)
