Unfortunately, just as they were passing through, Prudence returned home, and meeting them on the threshold, at once divined that they had been investigating in her absence. They noted her frightened face, and the look of relief that crossed it at the recollection that after all there was nothing to find. The medical lady thought it best to carry off their proceedings with a high hand.

“Dear, dear!” she said, laughing; “don’t look so startled, Miss Semaphore. We thought that as we saw or heard nothing of you at tea, we had better see you or your sister, and enquire if we could be of use to her in your absence; but you were both out.”

“Yes,” said Prudence, breathlessly, “we were both out; and I must say, Miss Lord, I consider it a great liberty for you and Mrs. Whitley to have entered my room and my sister’s under the circumstances.”

“Highty toity,” responded the medical woman, “we were trying to do our duty by your unfortunate sister, whom you left without proper medical attendance during her illness, and have apparently taken out of her sick bed this night at the risk of her life, and conveyed away without the smallest necessary precaution.”

Terrible is the wrath of the sheep. Prudence stood at bay in a towering rage.

“Allow me to tell you, madam,” she said, “that you know nothing at all about it. My sister is perfectly well, never better in her life, and I won’t be dictated to by you, or Mrs. Whitley either, as to any course of action I think fit to take.”

“Well, I’m sure,” gasped the medical woman, “this is what one gets for trying to be kind to some people. Come away, my dear Mrs. Whitley, and leave this—person. Far from thanking us for our thoughtfulness to her sister and herself, she only insults us. Of course if poor Miss Augusta dies from want of proper care, we shall not be to blame,” and, with much dignity, the two ladies swept downstairs, to tell the result of their mission.

That something was horribly wrong, all the boarders were agreed, but as to what that something was, they differed. Was Miss Augusta Semaphore living or dead? If living, what was the nature of the mysterious disease with which she was afflicted that necessitated such prompt and secret action on the part of her easy-going sister?

Mrs. Whitley, as one who had visited her room, was terrified at this view of the case, and went into strong hysterics at the idea of having perhaps contracted some terrible malady during her investigations. She was not to be calmed until both she and the medical woman, by the advice of the latter, went through a course of thorough fumigation and disinfection.

Where was Augusta now? That was another interesting theme for speculation. Somewhere near, apparently, since Major Jones had seen Prudence by herself in Tate Street shortly after dinner. Nothing else was talked of all day, but as Prudence came down calmly to meals, seemingly happier and more composed than she had been for some days, excitement began to die down. Perhaps there was nothing in it after all. Augusta was queer; she might have insisted in going off in the night like that. Anyhow, nothing much could be wrong, or Prudence would never look so cheerful. As for her having gone mad, or murdered her sister, even Mrs. Whitley now laughed at the idea; but the medical woman still clung to her belief that all was not right.
