Note 236 — Chapter V

A practical illustration of the methods freely employed by statesmen of the period will serve to throw fuller light upon this portion of our inquiry. In the service of the government was one Thomas Phelippes,[236] by trade a "decipherer," who was employed to "make English" of intercepted letters written in cipher. His services had been largely used in connection with Mary, Queen of Scots, some of whose letters he thus interpreted, having it in his power, as Mr. Tytler remarks, to garble or falsify them at pleasure.[237] Moreover, to serve the purposes of his masters, as he himself acknowledges,[238] he had upon occasion forged one side of a correspondence, in order to induce the person addressed to commit himself in reply.[239] At the time of the Gunpowder Plot, however, Phelippes had himself fallen under suspicion, on account of a correspondence with Hugh Owen, of whom we shall hear elsewhere. Accordingly, an attempt was made to hoist him with his own petard, and another agent, named Barnes, was employed by Cecil to write a letter, as coming from Phelippes (who was then in England) and carry it to Owen in Flanders in order to draw him out. At Dover, however, Barnes was arrested, being mistaken for another man for whom a watch was being kept. Thereupon, his papers being seized and sent to the Earl of Northampton, who appears not to have been in the secret of this matter, Cecil was obliged to arrest Phelippes at once, as though the letter were genuine, instead of waiting, as he had intended, in order to worm out more.
