Before crossing the Solway, Mary wrote to Elizabeth throwing herself on her hospitality. She followed hard on the heels of her missive, and awaited the reply at Carlisle, where the Catholic gentlemen of the North rallied to receive her. The situation indeed was a singularly embarrassing one for the English Queen. Mary claimed in fact that Elizabeth should either restore her, or allow her to appeal to those who would do so--that is, to France. To take her part unconditionally had its obvious dangers; not less obvious were the dangers of acceding to the alternative demand. To detain her in England, on the other hand, would inevitably make her the centre of Catholic intrigue. The most convenient arrangement would be to restore her under conditions which would minimise her power of becoming dangerous; and, in the meantime, she was perhaps less to be feared under careful supervision in England than anywhere else. So Elizabeth took the line of informing her that if she cleared herself of the charges of crimes such as made it impossible to support her if she were guilty, she should be restored; which being interpreted meant that there was to be an investigation, and Elizabeth would act on the findings. Murray on the other hand was in effect advised that the English Queen would not countenance him in levying war but that he might read between the lines of her instructions; in view of course of the fear that the party opposed to Murray might seek to procure French intervention. [Sidenote: A Commission of enquiry] Elizabeth was in fact in a position to dictate her own terms. Whatever right she might think fit to assume, whatever technical grounds she might assert for that right, Mary was effectively in her power. The Scots Queen--transferred for greater safety to Bolton, away from the dangerous proximity of the Border--indignantly repudiated the jurisdiction, demanded to be set at liberty, asseverated her own innocence. Elizabeth could not afford to set her at liberty; and with some plausibility declared that the innocence must be proved, before her rule could be re-imposed on a nation which had rejected it. Elizabeth quite evidently intended that the investigation should neither clear nor condemn her. Mary's objections were perfectly compatible with innocence. Submission might be taken as implying the recognition of English suzerainty; and if the investigation was to be earned just so far as suited her sister sovereign, if evidence was to be admitted, tested, or sup-pressed, with a view not to ascertaining truth but to securing a convenient judgment, innocence was no sort of reason for welcoming enquiry. [Footnote: Mr Froude (viii., Ed. 1866) informs us in one breath that Mary was impelled to protest by the consciousness of guilt (p. 253), but admits in the next that Elizabeth had no intention of allowing either her guilt or her innocence to be definitely proved (pp. 262, 270, 277).]
