Following coffee I was treated to a tour of the premises where, in one of the 22 individually decorated bedrooms, two signatures from people in The Story of Busta House are hand written on the stone wall! They are covered in glass for preservation, but the names are clearly visible, written in beautiful 1700's style.
I highly recommend you read up on the history of Busta House before visiting, as it really does change your outlook of the place when you are there. It did for me, at least. One of the descendants of Busta, Frances Scott, wrote another account: The True Romance of Busta, first published in 1934 which is available at Busta House itself. I'm thoroughly enjoying her read just now.
To tempt you to read it, I'd like to share a paragraph I enjoyed from the Authors Preface:
Nearly everybody, who is anybody, knows now where Shetland is; although, not so long ago (Shetland being "out of the map,") a great deal of ignorance, on this subject, prevailed, even among comparatively educated people. They know now that the Shetland Islands do not lie close to their sister group of the Orkneys; but are separated from them by a day's journey wild waste of stormy waters, with no intervening land, except the little Fair Isle (which cannot be approached by the steamer). The voyage is a hefty one, although (we understand) real sea-lovers love it; but the majority of land-loving mortals find it a bit of a penance. But once achieved, its pains are, for the time, forgotten, in the pleasure, variety and comparative peace of the new surroundings; it's pleasant, plausible inhabitants, and quiet, tranquil life. It speaks a great deal for the charm of the islands, than in spite of the rigours of the journey, people, having once visited them, often apparently cannot resist repeating the experiment, but return again and again to the scene of their enchantment.
