Nash describes Achilli's journey to England thus: had been imprisoned (in a monastery) by the Inquisition for heresy, he claimed, but actually for a series of sexual offences against under-age young women. He had been "rescued" from the Inquisition by a group of English ultra-Protestants as a hero six months before the Papal Aggression crisis broke. He was received by the Foreign Secretary, Lord Palmerston, greeted at a public meeting at Exeter Hall with a specially written hymn, "Hail Roman prisoner, Hail" and given a chapel in London. His "Dealings with the Inquisition" was a best seller. In his public lectures, sponsored by the Evangelical Alliance, he professed to the errors of Catholicism and to be a sincere Protestant, and his exciting account of the cruelties of the Inquisition made him a credible and popular anti-Catholic speaker.
