ITV’s six part factual drama, White House Farm, produced by New Pictures revolves around one fateful night in August 1985 when five members of the same family were murdered at an Essex farmhouse; Sheila Caffell, her twin six-year-old sons, Daniel and Nicholas, and her parents, Nevill and June Bamber. 　　The series will seek to provide fresh insight into this family tragedy and the contested accounts of the events that took place at White House Farm. Based on extensive research, interviews and published accounts including, ‘The Murders at White House Farm’ by Carol Ann Lee with additional material from ‘In Search of The Rainbow’s End’ by Colin Caffell, husband of Sheila and father to Daniel and Nicholas Caffell. 　　Essex Police initially believed that Sheila, who had mental health problems, had murdered her own family before turning the gun on herself. But Detective Sergeant Stan Jones had doubts about the murder-suicide theory, and about Sheila’s brother Jeremy Bamber, who first called the police to the farm. Eventually it was Jeremy Bamber who was charged and convicted of the murders of his own parents, sister and nephews. Bamber is currently serving life imprisonment without the possibility of parole. He is one of the few prisoners in the UK subject to a whole-life order. Bamber still maintains his innocence.
