Campion landed at Dover late in June, 1580, and reached London at the end of the month. There was an immediate rush to hear him, and Lord Paget was persuaded to lend his great hall at Paget House in Smithfield to accommodate a congregation for the feast of Saints Peter and Paul. The sermon was delivered on the text from the Gospel of the day, _Tu es Christus, Filius Dei vivi_. The hall was filled, and the impression caused by the sermon was profound; but the number of hearers had been imprudently large. Though no arrests followed, the persecutors took the alarm, and increased their activity to such an extent that large gatherings had for ever to be abandoned; and after a couple of weeks both Campion and Persons left London to escape the notice of the pursuivants, whose raids and inquisitorial searches were making the lot of Catholics in town unbearable, whereas in the country the pursuit was far less active, and could be much more easily avoided. The two Fathers met for the last time at Hoxton, then a village outside London, to concert their plans for the next couple of months, and were on the point of starting, each for his own destination, when a Catholic of some note rode up from London. This was Thomas Pounde, of Belmont or Beaumont, near Bedhampton, a landed gentleman of means, an enthusiastic Catholic, and for the last five years or so a prisoner for religion. Mr. Pounde's message in effect was this. "You are going into the proximate danger of capture, and if captured you must expect not justice, but every refinement of misrepresentation. You will be asked crooked questions, and your answers to them will be published in some debased form. Be sure that whatever then comes through to the outer world will come out poisoned and perverted. Let me therefore urge you to write now, and to leave in safe custody, what you would wish to have published then, in case infamous rumours should be put about during your incarceration, rumours which you will then not be able to answer or to repudiate." Father Persons seems to have agreed at once. Campion at first raised objections, but soon, with his ever obliging temper, sat down at the end of the table and wrote off in half an hour an open letter _To the Lords of Her Majesty's Privy Council_, afterwards so well known as _Campion's Challenge._ 3.
