Thus it cannot be concealed that, on July 29 (granting Letter IV to have a basis), the plot, as far as Logan knew, was ‘in the air.’ If Fastcastle was to be used by the conspirators, it must have been taken in the rough, on the chance that it was provided, or that Gowrie could bring his own supplies from Dirleton by sea. This extreme vagueness undeniably throws great doubt on Logan’s part in the plot; Letter IV, if genuine, being the source of our perplexity. But, if it is not genuine, that is, _in substance_, there is only rumour, later to be discussed, to hint that Logan was in any way connected with Gowrie. We left Bower and Logan conversing dolefully some days after the failure of the plot. At this point the perhaps insuperable difficulty arises, why did they not, as soon as they returned from Edinburgh, destroy every inch of paper connected with the conspiracy? One letter at least (Logan’s to Gowrie, July 29) was not burned, according to Sprot, but was later stolen by himself from Bower; though he reserved _this_ confession to the last day of his life but two. We might have expected Logan to take the letter from Bower as soon as they met, and to burn or, for that matter, swallow it if no fire was convenient! Yet, according to Sprot, in his final confession, Logan let Bower keep the damning paper for months. If this be true, we can only say _quos Deus vult perdere prius dementat_. People do keep damning letters, constant experience proves the fact. After Bower had met Logan in his melancholy mood, he rode away, and remained absent for four days, on what errand Sprot did not know, and during the next fortnight, while Scotland was ringing with the Gowrie tragedy, Sprot saw nothing of Logan. Next, Logan went to church at Coldinghame, on a Sunday, and met Bower: next day they dined together at Gunnisgreen. Bower was gloomy. Logan said, ‘Be it as it will, I must take my fortune, and I will tell you, Laird Bower, the scaffold is the best death that a man can die.’ Logan, if he said this, must have been drunk; he very often was. It was at this point, in answer to a question, that Sprot confessed that Logan’s letter to Bower (No. II) was a forgery by himself. The actual letter, Sprot said, was dictated by Logan to him, and he made a counterfeit copy in imitation of Logan’s handwriting. We have stated the difficulties involved in this obvious falsehood. Sprot was trying every ruse to conceal his alleged source and model, Letter IV.
