Allen and Parsons went to Rome again in 1585, and there Allen remained for the rest of his life. In 1587, whilst he was the subject of the intrigue by Philip's agents, he wrote, helped by Parsons, a book in defence of Sir William Stanley, an English officer who had surrendered the town of Deventer in Overijssel, part of the territory of the modern Kingdom of the Netherlands, to King Philip's armies. Allen wrote that all Englishmen were obliged, under the pain of eternal damnation, to follow that example, as Elizabeth was "no lawful queen" in the eyes of God.
