The private letters to Scotland were written by Robert Cecil and
Henry Howard. James's letters were written by Mar, Bruce and perhaps Mar's kinsman,
Thomas Erskine of Gogar. Some of the letters were sent to England as if they were meant for the
Duke of Rohan in France and so arrived in England to be added to the "
diplomatic bag". The 18th-century historian
Thomas Birch suggested that a Scottish representative in London,
James Hamilton and a colleague
James Fullerton, were involved in sending the letters to Scotland. Hamilton had kept a school in Dublin, and later James made him
Viscount Clandeboye. James Hamilton was accredited by James VI to reside in London by his letters to Elizabeth and Robert Cecil on 4 August 1600. James said that Hamilton would be a "remaining agent", the equivalent of
George Nicolson in Edinburgh. criticised
Henry Howard's verbose writing style. The English diplomat
Henry Wotton later gave an anecdote that Elizabeth had once noticed mail arriving from Scotland. She demanded to see it, and Cecil made to open the satchel (which Wotton called a 'budget') but told the Queen it was filthy and smelled bad, and she could have the letters after they were aired. It remains unclear if Elizabeth was actually unaware of any detail of Cecil's negotiations, as the historian
Geoffrey Elton assumed. Henry Wotton himself came to Scotland in September 1601 from Florence. Posing as an Italian, Octavio Baldi, he met James and remained in character for three months. James discussed Wotton's arrival with Edward Bruce,
Sir George Home, and the Earl of Mar. The English resident
George Nicholson was unaware that the "Italian" was Wotton. Wotton later wrote that his mission was from
Ferdinando de' Medici to advise James of a poison plot against him and bring a gift of antidotes. Some of the letters, as was quite usual in diplomatic correspondence, used numbers to refer to individuals rather than names; James was '30', Mar was '20', Robert Cecil was '10', Bruce '8', and Northampton '3'. By June 1602, James wrote of how Cecil and his colleague "40" had "so easily settled me in the only right course for my good, [and] so happily preserved the Queen's mind from the poison of jealous prejudice." The diplomat
David Foulis wrote to the Earl of Mar for London on 3 December 1601, after the
Duke of Lennox had left London. Foulis criticised a scheme, "a purpose", involving the Duke at the instigation of
James Sempill of Beltrees and the lawyer
Thomas Hamilton and thought the king should threaten them with hanging. Beltrees had written to "10", Sir Robert Cecil, in the Duke's name. Such diplomatic initiatives, outside the circle of the secret correspondents, were jealously resented. A letter from number "7" mentions a list of English gentlewomen of the "greatest account" sent to King James. This was written when Elizabeth had a "rheum" in her arm and was losing sleep through grief for her former favourite, the Earl of Essex. "7" wanted Foulis to carry King James' letters to London. A separate "public" correspondence between Elizabeth and James continued. The historian
John Duncan Mackie thought that the tone of the public letters had become more cordial than in previous years. The irregular subsidy that Elizabeth paid to James (in cash or jewellery) was continued. James VI sent Henry Howard, later
Earl of Northampton, a jewel with three precious stones including a ruby as "his first token". James criticised Howard's writing style. In May 1602 he wrote how "my own laconic style" compared with Howard's "ample Asiatic and endless volumes". The 19th-century historian
Patrick Fraser Tytler noted the excessive flattery used by Howard and the effort made to exclude others from the discussions. Although James noticed and challenged Howard's attempts to direct his actions with regard to other channels of communication, Tytler summed up their successful co-operation:At all events, nothing could have been more secretly or adroitly managed than the whole correspondence between Howard, Cecil, and the Scottish king. No one had the least suspicion of the understanding that existed between the trio. According to
Godfrey Goodman, King James "wrote and did acknowledge that for some six years before the Queen died he held correspondence with [Cecil], and that he found him a very wise, able, faithful servant. ==Secrecy and the Scottish queen==
