Sixteen months ago, MacIan had been arrested for a violation of the Stabbing Act. The stabbee had been an Englishman: a Whig who had mocked him in a coffee-house, pretending that he could not understand a word the Scotsman was saying. The Prosecutor had been the Whig’s widow: a more formidable opponent. By dint of various connivings and intrigues, she managed to trump up a few moments’ impulsive dirk-work into an act of High Treason. Exploiting the fact that her late husband had been a Member of Parliament, she had convinced a magistrate that the imbroglio had, in truth, been an act of international espionage carried out by a Scottish Jacobite Tory against an important member of Her Majesty’s Government. So MacIan had been committed to the Tower instead of Newgate Prison. He had not set foot beyond the Inner Wall since then. Now, though, he staged half of an escape by thrusting his head and shoulders out the window.
