Note: contains spoilers for White House Farm.
At the end of White House Farm, ITV's true-crime dramatisation of the murders of June (Amanda Burton) and Nevill Bamber (Nicholas Farrell), their adopted daughter Sheila Caffell (Cressida Bonas) and her sons Nicholas and Daniel, we are given some answers.
We're told that Colin Caffell (Mark Stanley), Sheila's ex-husband and the father of Nicholas and Daniel, remarried in 1999 and went on to study psychotherapy and bereavement. He eventually retired from the field and is now working as a sculptor and a potter.
Colin also wrote a book, In Search of the Rainbow's End: Inside the White House Farm Murders.
We also find out that Detective Sergeant Stan Jones (Mark Addy), who was initially the family liaison – a title that has only come into use more recently – but went on to play an increasingly bigger role in the investigation, retired in 1991 and died in 2014.
Someone who isn't mentioned is Detective Chief Inspector Thomas "Taff" Jones, played by Stephen Graham.
What to Read Next
In the series, he clashed with anyone who questioned his belief that Sheila had carried out the shootings before taking her own life, in particular Stan, who continued to seek out the truth.
The last time we saw of him was at the beginning of the final episode after he was removed from the investigation.
"I guess it's my turn to take some leave," he said to Stan, before going on to say that he "never rated" him.
"No ambition, that's what I thought," he added, before accusing his colleague of "climbing" all over him to make himself look good.
"Young Bamber, you think he's a selfish arrogant twat, but that doesn't make him a murderer," he said. "I hope for his sake you can tell the difference."
White House Farm has been criticised by Essex police for the way in which Taff is portrayed.
The more Stan Jones persisted in his pursuit of Jeremy, the more irate Taff became, using a combination of rank and intimidating behaviour to dismiss any concerns about Jeremy and the way in which the case was being handled, particularly in regards to evidence.
Not only were the bodies of June, Nevill, Sheila, Nicholas and Daniel cremated while officers such as Stan were expressing their concerns, but blood-stained items from the Bambers' house were destroyed before the case was closed.
According to The Sun, ex-Detective Sergeant Ken Luxford described White House Farm as a "character assassination of Taff", and detective Len Jarman said Taff was left a "broken man" following the investigation.
"He highlighted what he was confronted with, why he formed his opinions based on available evidence at the time and how differing Home Office experts had concurred with his views," Jarman added.
"Yet when some kept telling him that Jeremy had 'done it', he asked them for evidence to push him to reconsider. But none was forthcoming."
ITV defended the drama in a statement to Digital Spy: "The drama series is based on extensive research and we are satisfied that we have depicted individuals fairly."
There is very little information out there about Taff, but a number of outlets have reported that he died in 1986 after falling off a ladder at home. This was before Jeremy's trial took place.
Despite his death, it's unclear whether he would have featured in the series' final moments, such as the trial, given that the investigation had been taken out of his hands.
White House Farm continues on Wednesday, February 5 at 9pm on ITV.
