“Why!—it must be some one from that woman at Lefford!” exclaimed Miss Deveen, in an undertone to me. “Oh no; I remember now, Johnny; Dr. Knox was the step-son; he was away, and had nothing to do with it. Show Dr. Knox in, George.”

A tall man in black, whom one might have taken anywhere for a doctor, with a grave, nice face, came in. He said his visit was to Miss Carey, as he took the chair George placed near his mistress. Just a few words, and then we knew the whole, and saw a small sealed-up box in his hand, which contained the remains of the bank-note.

“I am more glad than if you brought Janet a purse of gold!” cried Miss Deveen, her eyes sparkling with pleasure. “Not that I think any one could have doubted her, Dr. Knox—not even your step-mother, in her heart,—but it is satisfactory to have it cleared up. It has made Miss Carey very ill; but this will set her at rest.”

“Your servant told me Miss Carey was ill,” he said. “It was for her I asked.”

With a face of concern, he listened to what Miss Deveen had to say of the illness. When she spoke of Janet’s fright at seeing the policeman at the Colosseum, his brow went red and he bit his lips. Next came the sleep-walking: she told it all.

“Her brain and nerves must have been overstrained to an alarming degree,” he observed, after a short silence. “Mr. Shuttleworth, who attended her at the time, spoke to me of the shock to the system. But I hoped she had recovered.”

“She would never have recovered, Dr. Knox, as long as the dread lay upon her that she was to be criminally prosecuted: at least, that is my opinion,” said Miss Deveen. “I believe the chief thing that ails her is fright. Not a knock at the door, not the marching past the house of a policeman, not the sudden entrance of a servant into the room, but has brought to her a shock of agonizing fear. It is a mercy that she has escaped brain-fever. After all, she must possess a good constitution. The sight of that Lefford man at the Colosseum did great mischief.”

“It was unfortunate that he should happen to be there,” said Dr. Knox: “and that the man should have dared to accost her with his insolence! But I shall inquire into it.”

“What you have in that box will be the best medicine for her,” said Miss Deveen. “It will speedily effect a cure—or call me an untrue prophet. Dear me! how strangely things come out!”

“May I be allowed to see Miss Carey?” asked Dr. Knox. “And to—to tell her the story of her clearance in my own way?”
