Things like crowns had a troublesome effect on clever folks; it was best to leave all the reigning to the kind of people whose eyebrows met in the middle. Three witches gathered on a lonely heath. A king cruelly murdered, his throne usurped by his ambitious cousin. A child heir and the crown of the kingdom, both missing. The omens are not auspicious for the new incumbent, for whom ascending this tainted throne is a more complicated affair than you might imagine, particularly when the blood on your hands just won"t wash off and you"re facing a future with knives in it... Это и многое другое вы найдете в книге Wyrd Sisters (Pratchett, Terry)
