Let us hope that services so long, so faithful, and so important, at length received their reward. That they probably did may be surmised from the following account of the close of his active career, given by the Cornish historian Carew: 'After ambassades and messages, and many other profitable employments of peace and warre, in his prince's service, to the good of his country, (Sir Henry Killigrew) hath made choyce of a retyred estate, and, reverently regarded by all sorts, placeth his principal contentment in himselfe, which, to a life so well acted, can no way bee wanting.' Lord Burleigh's instructions to him,[72] on the subject of his Scotch mission, written with his own hand, dated 10th September, 1572, especially as to getting Mary Queen of Scots out of the kingdom, and delivering her to the Regent's party, form a most interesting document. The letter closes thus: 'Herein yow shall, as Comodite shall serve yow, use all good Spede, with the most Secresy that yow can, to understand their Mynds; _and yet so to deale to your uttermost, that this Matter might be rather Oppened to yow, than yourself to seme first to move it_....' Another object of his momentous mission to Scotland, as to which Elizabeth gave him her instructions with her own mouth, was to impress upon Mary Queen of Scots a sense of her faults, her duties, and her danger--a vain task! Froude gives an account of the interview, which took place after Darnley's murder. 'The windows at Holyrood were half-closed, the rooms were darkened, and in the profound gloom the English Ambassador was unable to see the Queen's face, but by her words she seemed very doleful.' And at length, having extorted from her a promise that Bothwell should be put upon his trial, Killigrew went back to London in less than a week, after having carried out his difficult and delicate duty 'like a loyal servant.'
