And when Mary's secretary, Lethington, urged that Henry's testament, which alone stood in their way, should be examined, alleging that it had not been signed by the king, she paid no attention to this imprudent request.[197] The circumstances wherein Mary found herself placed on her arrival in Scotland were sufficiently embarrassing to divert her attention from any regular scheme against Elizabeth, though she may sometimes have indulged visionary hopes; nor it is probable that with the most circumspect management she could so far have mitigated the rancour of some or checked the ambition of others, as to find leisure for hostile intrigues. But her imprudent marriage with Darnley, and the far greater errors of her subsequent behaviour, by lowering both her resources and reputation as far as possible, seemed to be pledges of perfect security from that quarter. Yet it was precisely when Mary was become most feeble and helpless, that Elizabeth's apprehensions grew most serious and well founded. At the time when Mary, escaped from captivity, threw herself on the protection of a related, though rival queen, three courses lay open to Elizabeth, and were discussed in her councils. To restore her by force of arms, or rather by a mediation which would certainly have been effectual, to the throne which she had compulsorily abdicated, was the most generous, and would probably have turned out the most judicious proceeding. Reigning thus with tarnished honour and diminished power, she must have continually depended on the support of England, and become little better than a vassal of its sovereign. Still it might be objected by many, that the queen's honour was concerned not to maintain too decidedly the cause of one accused by common fame, and even by evidence that had already been made public, of adultery and the assassination of her husband. To have permitted her retreat into France would have shown an impartial neutrality; and probably that court was too much occupied at home to have afforded her any material assistance. Yet this appeared rather dangerous; and policy was supposed, as frequently happens, to indicate a measure absolutely repugnant to justice, that of detaining her in perpetual custody.[198] Whether this policy had no other fault than its want of justice, may reasonably be called in question.
