"You have done wisely," said my friend. "But have you told me all?"

"Yes, all."

"Miss Roylott, you have not. You are screening your stepfather."

"Why, what do you mean?"

For answer Holmes pushed back the frill of black lace which fringed the hand that lay upon our visitor's knee. Five little livid spots, the marks of four fingers and a thumb, were printed upon the white wrist.

"You have been cruelly used," said Holmes.

The lady coloured deeply and covered over her injured wrist. "He is a hard man," she said, "and perhaps he hardly knows his own strength."

There was a long silence, during which Holmes leaned his chin upon his hands and stared into the crackling fire.

"This is a very deep business," he said at last. "There are a thousand details which I should desire to know before I decide upon our course of action. Yet we have not a moment to lose. If we were to come to Stoke Moran to-day, would it be possible for us to see over these rooms without the knowledge of your stepfather?"

"As it happens, he spoke of coming into town to-day upon some most important business. It is probable that he will be away all day, and that there would be nothing to disturb you. We have a housekeeper now, but she is old and foolish, and I could easily get her out of the way."

"Excellent. You are not averse to this trip, Watson?"

"By no means."

"Then we shall both come. What are you going to do yourself?"

"I have one or two things which I would wish to do now that I am in town. But I shall return by the twelve o'clock train, so as to be there in time for your coming."

"And you may expect us early in the afternoon. I have myself some small business matters to attend to. Will you not wait and breakfast?"

"No, I must go. My heart is lightened already since I have confided my trouble to you. I shall look forward to seeing you again this afternoon." She dropped her thick black veil over her face and glided from the room.

"And what do you think of it all, Watson?" asked Sherlock Holmes, leaning back in his chair.
