Tree on a Hill S01E04 - Episode 4

What did Haydn see on the night of Glyn's disappearance? How much does he know? And how worried should Margaret and Clive really be? 

Margaret's cage is certainly rattled when she bumps into Haydn at chapel, and she can't help feeling that he knows more than he's letting on. Ruth is sniffing around, and Herbie is cornered into a confession about his relationship with Sylvia.
