The Lords were now, with these letters to justify them, in a relatively secure position. They could, and did, play off France against England: both of these countries were anxious to secure the person of the baby Prince, both were obliged to treat with the Lords who had the alliance of Scotland to bestow. Elizabeth wavered between her desire, as a Queen, to help a sister Queen, and her anxiety not to break with the dominant Scottish party. The Lords had hanged a retainer of Bothwell, Blackader, taken after Carberry, who denied his guilt, and against whom nothing was proved: but he had a Lennox jury. Two other underlings of Bothwell, his porter Powrie and his ‘chamber-child’ Dalgleish, were taken and examined, but their depositions, as reported by the Lords themselves, neither implicated Mary, nor threw any light on the date at which the idea of an explosion was conceived. It was then believed to have been projected before Mary went to bring Darnley from Glasgow. This opinion reflected itself in what was conceivably the earlier forged draft, never publicly produced, of the long ‘Glasgow Letter’ (II.) Later information may have caused that long letter to be modified into its present shape, or, as probably, induced the Lords to fall back on a partly genuine letter, our Letter II. The Lords did by no means make public use, at first, of the Letters which they had found, and were possibly garbling. We shall later make it clear, it is a new point, that, on the very day of the reading, the Lords sent Robert Melville post haste to Elizabeth, doubtless with verbal information about their discovery. Leaving Edinburgh on June 21, the day of the discovery, Melville was in London on June 23 or 24, dispatched his business, and was in Berwick again on June 28. He carried letters for Moray in France, but, for some reason, perhaps because the letters were delayed or intercepted, Moray had to be summoned again. Meanwhile the Lords, otherwise, kept their own counsel.[212] For reasons of policy they let their good fortune ooze out by degrees. On June 25, Drury, writing from Berwick, reports that ‘the Queen has had a _box_,’ containing papers about her intrigues with France. ‘It is promised Drury to have his part of it.’ This rumour of a ‘box’ _may_ refer to the capture of the Casket.[213] On June 29, Drury again wrote about the ‘box,’ and the MSS. in it, ‘part in cipher deciphered.’ Whether this ‘box’ was the Casket, a false account of its contents being given to Drury, is uncertain. We hear no more of it, nor of any of Mary’s own papers and letters to her: no letters to her from Bothwell are reported.
