On 2 December 1583,
Sir Edward Stafford, the English ambassador to the French court, wrote from Paris to Sir Frances Walsingham that: "Lord Paget, with Charles Paget and Charles Arundel, suddenly entered my dining chamber before any one was aware of it, and Lord Paget says they came away for their consciences, and for fear, having enemies". They also told him that "for all things but their consciences they would live as dutifully as any in the world". After this, Charles Paget, in conjunction with Morgan and other malcontents at home and abroad, continued their plans, which were well known to the English government, and in June 1584
Sir Edward Stafford, the English ambassador to the French court, made a formal demand, in the name of Queen Elizabeth, for the surrender of
Thomas Paget, Charles Paget, Charles Arundel, Thomas Throckmorton, and Thomas Morgan for having conspired against the life of the English Queen. The
King of France, however, refused to deliver them up, although he did imprison Morgan in the
Bastille, and sent his papers to Queen Elizabeth. He was regarded with the utmost distrust and suspicion by Walsingham, who, in a despatch sent to Stafford on 16 December 1584, wrote that: "Charles Paget is a most dangerous instrument, and I wish, for Northumberland's sake, he had never been born". Thomas Morgan introduced Paget to
Albert Fontenay, a brother of Mary, Queen of Scots' French secretary Claude Nau. They met
Claud Hamilton in Paris in January 1586, before his return to Scotland. They hoped Hamilton would be an advocate for Mary in Scotland with her son
James VI. Paget wrote to Mary and Nau, mentioning Fontenay's "great comfort and friendship" and his "many friendly offices". Mary wrote to Paget in May 1586, after receiving five letters from him, with an "infinite number" of other letters written in cipher code. Mary hoped that Spain would invade England, and Scotland would assist or remain neutral. Her son, James VI, would be a hostage and brought up as a Catholic. She wanted Paget to discuss the scheme with her ally Claud Hamilton, who was in Scotland and could build support amongst the Scottish nobility. Mary's secretaries Claude Nau and
Gilbert Curle were arrested in August 1586. Her correspondence was examined. Curle was made to certify on a copy of one of Mary's letters to Paget that she had first given him a draft in French, which he translated into English.
William Cecil added a further note, that this was Curle's "superscription". Although all his plots had signally failed, Paget appears to have clung to the hope that the Protestant religion in England could be subverted by a foreign force. Writing under the signature of 'Nauris,' from Paris to one Nicholas Berden
alias Thomas Rogers (a courier and a spy for Walsingham), on 31 January 1588 he observed, in reference to the anticipated triumph of the
Spanish Armada: "When the day of invasion happens, the proudest Councillor or Minister in England will be glad of the favour of a Catholic gentleman". In the same letter, he stated that all Walsingham's alphabets or
ciphers had been interpreted by him. Berden sent copies of Paget's cipher alphabets to Walsingham's cryptographer
Thomas Phelippes to gather evidence against conspirators. ==Brussels==
