The Reverend Myles, who was of the honest party, but not as yet blown upon by suspicion, seemed to him his only help and instrument. For a long while, when the Colonel had gone, the pair debated the means of escape, but found no issue; and Rose brought her white face back to the Tower, and the Parson's spirits drooped, so that at last his health began to fail. He was therefore allowed to drive out in a coach to any place within ten miles of London in the custody of a warder, and on his parole to return before dark. Of this favour he made frequent use, and no doubt the sight of the busy faces in the streets urged him yet more to make a bid for his freedom. Now these journeys of the Parson to take the air set Father Myles Macdonnell upon a pretty plan, which he imparted to Rose and to George. 'You drive one afternoon up into Highgate Woods--d'ye follow that? I have half-a-dozen well-disposed persons hiding in a clump of trees who will take care of your warder--d'ye see? There will be a stout horse tethered to a branch close by, and a lugger waiting off the coast of Essex--'but the Parson would hear no more of the scheme. 'I have given my parole to come back to the Tower before dark,' said he, and glanced at Rose, who was looking away, to strengthen him in his objection. 'I cannot break it, can I, Rose? I have given my parole. I am not one of the Butcher Cumberland's officers. We must keep troth.' Rose made an effort and agreed. 'Yes,' said she, 'he has given his parole, and he cannot break it.' 'Not so long as he's a lost Protestant,' said the Reverend Father. He tapped George on the knee, and continued in a wheedling voice: 'It is a matter of religion, d'ye see? Just let me convert you. I can do it in a twinkling, and so I shall save your body and your soul in one glorious moment.' 'How so? 'asked the Parson with a laugh, for he was by this time well used to his kinsman's efforts to convert him. 'How shall a Catholic creep out of the Tower more easily than a Protestant?' 'Because a Catholic can break his parole. It's a great sin, to be sure, but I can absolve him for it afterwards.' To Mr. Kelly's thinking (and, indeed, to Mr. Wogan's) this was no sterling theology, and he would not be persuaded. Another device had to be invented, and when at last a satisfactory plan was resolved upon, the plotters must wait for the quick nightfalls of autumn.
