As to what took place at the flat, they had a choice between the evidence of Hill and the evidence of the girl Fanning. Hill had told them that he had tried to dissuade the prisoner from going to Riversbrook to burgle the premises, because his master had returned unexpectedly; Fanning had told them that the prisoner was in favour of postponing the crime, but that Hill had urged him to carry it out. Which story was the more probable? What reliance could they place on the evidence of Fanning? He did not wish to say that the witness was utterly vicious and incapable of telling the truth--a description that the defence had applied to Hill--but they must take into consideration the fact that Fanning was the prisoner's mistress. Was it likely that a woman, knowing her lover's life was at stake, would come here and speak the truth, if she knew the truth would hang him? He was sure that the jury, as men who knew the world thoroughly, would not hesitate between the evidence of Hill and that of Fanning. The case for the defence depended to a great extent on the plan of Riversbrook which Hill candidly admitted he had drawn. His learned friend had called evidence to show that the paper on which the plan was drawn was of a quality which was not procurable by the general public. That might be so, but what his learned friend had not succeeded in doing, and could not possibly have hoped to succeed in doing, was to show that Birchill could not have obtained possession in any other way of paper of that kind. Yet it was necessary for the defence to prove that, in order to prove that the plan was not drawn at Fanning's flat by Hill under threats from Birchill, but that Hill had drawn it at Riversbrook, and that he gave it to Birchill in order to induce him to consent to the proposal to break into the house. There were dozens of ways in which paper of this particular quality might have got to the flat. Might not Birchill have a friend in His Majesty's Stationery Office? Was it impossible that the witness Fanning had a friend in that Office, or in one of the Government Departments to which the paper was supplied? Was it impossible in view of her relations with the victim of this crime for Fanning to have obtained some of the paper at Riversbrook and to have taken it home to her flat? She had sworn in the witness-box that she had not had paper of that kind in her possession, but with her lover's life at stake was she likely to stick at a lie if it would help to get him off?
