She was discouraged

Here was plainly a niece whose soul had been passed through the wringer, a niece who had drained the bitter cup and, what is more, had found a dead mouse at the bottom of it. Her demeanour reminded him of a girl he had once taken to Henley Regatta - at the moment when she had discovered that a beetle had fallen down the back of her summer sports wear.
