Ghost_of_Barry_Fairbrother (sometimes referred to as simply Ghost of Barry Fairbrother or Barry Fairbrother's Ghost) was an Internet username used by three anonymous posters on the Pagford Parish Council's website. The account was created by hacking the original account of the deceased Barry Fairbrother.
The account was originally created by Andrew "Arf" Price by using SQL hacking to bypass the website's weak security measures. He then used the account to post scandalous, but nevertheless true allegations regarding his father Simon "Si-Pie" Price. Though the allegations were later removed, they proved extremely damaging, leading to Simon's withdrawal from the race for the Pagford Parish Council and increasing his paranoia.
Finally, Andrew Price used the account to reveal the affair between Howard Mollison, and his business partner Maureen "Mo". These allegations drove Howard to have a stress-induced heart attack, and nearly caused Howard's wife, Shirley Mollison, to conspire to murder Howard with an epi-pen. Shirley never had the opportunitty to murder Howard, as she was the one who found him on the floor in the midst of his heart attack.
Stuart took all blame for the posts made under the username and Andrew and Sukhvinder were never discovered regarding their complicity in the events.
