Robertson dates even more confidently than Buchanan, the commencement of Mary's love for Bothwell at a period prior to her delivery. But upon this hypothesis, it is surely odd, that Murray and Argyle were permitted by the Queen to reside in the Castle previous to and during her confinement, whilst the same favour was peremptorily refused to Bothwell; and it is no less odd, that shortly after her delivery, Secretary Maitland, at the intercession of the Earl of Athol, was received once more into favour, in direct opposition to the wishes of Bothwell. It is no doubt possible, that notwithstanding this presumptive evidence to the contrary, Mary may at this very time have had a violent love for Bothwell; but are we to give credit to the improbability, merely because Buchanan was the slave of party feeling, and Robertson disposed to be credulous? Are the detected fabrications of the one, entitled to any better consideration than the gratuitous suppositions of the other? "Strange and surprisingly wild," says Keith, "are the accounts given by Knox, but more especially by Buchanan, concerning the King and Queen about this time. I shall not reckon it worth while to transcribe them here; and the best and shortest confutation I could propose of them is, to leave my readers the trouble, or rather satisfaction, to compare the same with the just now mentioned abstracts (of despatches from Randolph to Cecil) and the three following authentic letters," from the French and Scottish ambassadors and the Queen's Privy Council.[145] Robertson, it is true, after having asserted, that "Bothwell all this while was the Queen's prime confident," and that he had acquired a "sway over her heart," proceeds to confess, that "such delicate transitions of passion can be discerned only by those who are admitted near the persons of the parties, and who can view the secret workings of the heart with calm and acute observation." "Neither Knox nor Buchanan," he adds, "enjoyed these advantages. Their humble station allowed them only a distant access to the Queen and her favourite; and the ardour of their zeal, and the violence of their prejudices rendered their opinions rash, precipitate, and inaccurate." This is apparently so explicit and fair, that the only wonder is, upon what grounds Robertson ventured to make _his_ accusation of Mary, having thus shown how little dependence was to be placed on the only authorities which supported him in it. It appears that he came to his conclusions by a process of his own, which rendered him independent both of Knox and Buchanan. "Subsequent historians," he says, "can judge of the reality of this reciprocal passion only by its _effects_." Robertson must of course have been aware that he thus opened the gate to a flood of uncertainty, seeing that the same effects may spring from a hundred different causes. If a man be found dead, before looking for his murderer, it is always proper to inquire whether he has been murdered.
