Worst of all, we learn from another intercepted letter of Garnet's, Catesby had for his own purposes circulated an atrocious slander against Garnet himself, although passing as his devoted disciple and friend: "Master Catesby," he wrote,[319] "did me much wrong, and hath confessed that he told them he asked me a question in Q. Elizabeth's time of the powder action,[320] and that I said it was lawful. All which is most untrue. He did it to draw in others." In view of this, and much else of a similar kind, it is difficult to read Father Gerard's _Narrative_, and more particularly Father Greenway's additions thereto, without a growing feeling that if Catesby sought counsel it was with no intention of being guided by it, and that his sole desire was to get hold of something which might serve his own purposes. We have already seen that a great deal of mystery attaches to Francis Tresham, who is generally supposed to have written the letter to Monteagle, and was clearly suspected by some of having done a great deal more; for the author of the _Politician's Catechism_ speaks of him as having access to Cecil's house even at midnight, along with another whose name is not given, these two being therefore supposed to have been the secretary's instruments in all this business. What is certain is, that Tresham did not fly like the rest when the "discovery" had taken place, not only remaining in London, and showing himself openly in the streets, but actually presenting himself to the council, and offering them his services. Moreover, though his name was known to the government, at least on November 7th, as one of the accomplices, it was for several days omitted from their published proclamations, and not till the 12th was he taken into custody. Being confined in the Tower, he was shortly attacked by a painful malady, and on December 23rd he died, as was officially announced, of a "strangury," as Salisbury assures Cornwallis "by a natural sickness, such as he hath been a long time subject to."[321] Throughout his sickness he himself and his friends loudly declared that should he survive it "they feared not the course of justice."[322] Such confidence, as Mr. Jardine remarks, could be grounded only on his possession of knowledge which the authorities would not venture to reveal, and it is not surprising that his death should have been attributed, by the enemies of the government, to poison. It is no doubt an argument against such a supposition that during his illness Tresham was allowed to be attended by his wife and a confidential servant. On the other hand, not only does Bishop Goodman inform us[323] that "Butler, the great physician of Cambridge," declared him to have been poisoned; but the author of _Mischeefes Mystery_, a violent government partisan, contradicts the notion of a natural death, by asserting that "Tresham murthered himself in the Tower."
