It was not the weekend after the murders:
She and the appellant spent the following weekend with Colin Caffell and on 12 August she went to the house in Goldhanger with the appellant. There he told her that the police had been a bit slack because they had not done all the fingerprinting at White House Farm. On 16 August Miss Mugford attended the funerals of Nevill and June Bamber with the appellant and then on 19 August the funerals of Sheila Caffell and her children. During that period the witness spoke of the appellant taking her out for frequent meals, and buying expensive clothes for himself and for her. She described the appellant's mood during this period as "very happy". After one of the funerals they drank champagne and cocktails.
111. Miss Mugford spent the weekend of 17-18 August 1985 with the appellant in Eastbourne and it was then that she began to ask how he could behave as he was doing. She kept telling him "£2,000 for five lives". The following week the couple went to Amsterdam for two days, staying in expensive hotels and eating out. On 27 August Miss Mugford returned alone to her lodgings in London and she told her friend Susan Battersby of what the appellant had done
