Ordeal by Innocence

Episode 2 (1x2)

:

The morning after Leo and Gwenda's party, Arthur tries to return to Sunny Point in an effort to clear Jack's name, but receives very little support from the Argyll family, who have Mickey unceremoniously escort him off the premises. Left with no option but to reveal everything he knows, he provides irrefutable proof that Jack is innocent. His revelation has devastating consequences for the members of the Argyll family, who begin to realise that if Jack did not kill Rachel, one of them must have.
