The new commission opened at Westminster (4th Dec. 1568). The lords brought forward their charges against the queen accusing her of complicity in the murder of her husband. In proof of this they produced a number of letters that were supposed to have been contained in a casket left behind him by Bothwell in Edinburgh, when he fled from that city in June 1567. This casket contained eight letters and some sonnets, which, if really written by Mary, proved beyond doubt that she was hand in glove with Bothwell in bringing about the murder of Darnley. The Casket Letters considered in the light of her own conduct furnished damaging evidence of Mary's guilt. Whether these letters were genuine or forged is never likely to be established with certainty,[32] but considering the character of Mary's opponents, their well-known genius for duplicity, the contradictory statements put forward by their witnesses and the indecent haste with which the whole enquiry was brought to a close, it is difficult to believe that the evidence of Mary's authorship was convincing. The commissioners acting on Mary's behalf laboured under grave disadvantages from the fact that their mistress was not at hand for consultation. As a consequence they made many mistakes in their pleadings, but they were on sure ground when they demanded that copies of the incriminating letters should be forwarded to Mary for examination. This demand, though supported by the French ambassador, was refused, and Mary was never allowed an opportunity to reply to the main charge brought against her. An offer was made that proceedings should be dropped if Mary would consent to resign the throne of Scotland in favour of her son, and when she refused this offer the conference was brought to a sudden termination. Moray and his friends were informed that "nothing had been produced against them as yet that might impair their honour and allegiance; and on the other part there had been nothing sufficiently produced or shown by them against the queen their sovereign, whereby the Queen of England should conceive or take any evil opinion of the queen her good sister for anything yet seen" (Jan. 1569).[33] The Earl of Moray and his companions were allowed to return to Scotland, and nothing more was done either to establish the innocence or the guilt of the Queen of Scotland. The object of Elizabeth and her advisers had been attained. They had blackened the character of Mary; they had driven a wedge between herself and her nobles, and had allowed Moray to return to Scotland to rule as an English dependent.
