On the evening of 7 August when they were alone, Julie said she asked Jeremy whether he had done it. He said he had not, but that he had arranged for a friend of his, Matthew MacDonald, to kill his family. He spoke of what he had told MacDonald as to ways of getting in and out of the farmhouse undetected and he said that one of his instructions was for MacDonald to ring him from the farm on the telephone which had the memory redial facility so that if the telephone was checked by the police it would provide him with an alibi.
Seems she was happy with that then.
