“But you know it was one of you, _certainly_,” she said, at last. “And I shall keep such a close watch upon you all that I’ll be bound to catch the guilty one at last. So whichever one of you it was that played the part of Judas, I want you to go away from Selwyn Heights and never darken these doors again!” But no one offered to go, and no one went. Each and all were indignant at her suspicions. “Miss Strangemore ought to know us better than to think that we could betray our sweet young mistress,” they said. “Why, we’ve been here ever since she was a little girl, and we love every hair of her head better than our own.” So the mystery remained a mystery still, although Miss Drusilla sternly flouted Kitty’s belief in the innocence of the servants. “It stands to reason that it was one of them, Kitty.
