sentences:  Mr Mertoun and his son had arrived as strangers, and resided for several years in the remaining rooms of the old mansion of the Earls of Orkney, the father leading a very secluded life, while the son Mordaunt became a general favourite with the inhabitants, and especially with the udaller, Magnus Troil, and his daughters, Brenda and Minna.On his way home from a visit to them, he and the pedlar Snailsfoot sought shelter from a storm at a farmhouse, at Hafra, home of Triptolemus Yellowley agent of the Chamberlain of Orkney and Shetland, and his sister Barbara.The visitors were amused with the Yellowley's penurious ways, and encountered Norna, a relative of Magnus Troil who was supposed to be in league with the fairies, and to possess supernatural powers.
