At one of his initial meetings with the McConvilles, Adams made it clear that he had what was, in effect, an alibi. ‘Thank God I was in prison when she disappeared,’ he said. This was not true. He had been released from Long Kesh in June 1972, in order to fly to London for the peace talks. Jean was abducted in December, and Adams was not locked up again until the following July. (‘That shouldn’t be taken out of context,’ Adams said later. ‘I got confused about the dates.’)
