The whole expression of his face changed in an instant—changed so darkly that she recoiled from him in terror, and put back the hair into the newspaper. He pounced on it directly; and, crunching it up in his hand, turned his grim threatening face and fiercely-questioning eyes on the landlady. While she was answering his inquiry, Madonna saw him look towards Zack’s bed; and, as he looked, another change passed over his face—the darkness faded from it, and the red scars on his cheek deepened in color. He moved back slowly to the further corner of the room from the folding-doors; his restless eyes fixed in a vacant stare, one of his hands clutched round the old newspaper, the other motioning clumsily and impatiently to the astonished and alarmed women to leave him.

Madonna had felt Patty’s hand pulling at her arm more than once during the last minute or two. She was now quite as anxious as her companion to quit the house. They went out quickly, not venturing to look at Mat again; and the landlady followed them. She and Patty had a long talk together at the street door—evidently, judging by the expression of their faces, about the conduct of the rough lodger up-stairs. But Madonna felt no desire to be informed particularly of what they were saying to each other. Much as Matthew’s strange behavior had surprised and startled her, he was not the uppermost subject in her mind just then. It was the discovery of her secret, the failure of her little plan for helping Zack with her own money, that she was now thinking of with equal confusion and dismay. She had not been in the front room at Kirk Street much more than five minutes altogether—yet what a succession of untoward events had passed in that short space of time!

For a long while after the women had left him, Mat stood motionless in the furthest corner of the room from the folding-doors, looking vacantly towards Zack’s bedchamber. His first surprise on finding a stranger talking in the passage, when he let himself in from the street; his first vexation on hearing of Zack’s accident from the landlady; his momentary impulse to discover himself to Mary’s child, when he saw Madonna standing in his room, and again when he knew that she had come there with her little offering, for the one kind purpose of helping the sick lad in his distress—all these sensations were now gone from his memory as well as from his heart; absorbed in the one predominant emotion with which the discovery of the resemblance between Zack’s hair and the hair from Jane Holdworth’s letter now filled him. No ordinary shocks could strike Mat’s mind hard enough to make it lose its balance—this shock prostrated it in an instant.

In proportion as he gradually recovered his self-possession so did the desire strengthen in him to ascertain the resemblance between the two kinds of hair once more—but in such a manner as it had not been ascertained yet. He stole gently to the folding-doors and looked into young Thorpe’s room. Zack was still asleep.

After pausing for a moment, and shaking his head sorrowfully, as he noticed how pale and wasted the lad’s face looked, he approached the pillow, and laid the lock of Arthur Carr’s hair upon it, close to the uninjured side of Zack’s head. It was then late in the afternoon, but not dusk yet. No blind hung over the bedroom window, and all the light in the sky streamed full on to the pillow as Mat’s eyes fastened on it.

The similarity between the sleeper’s hair and the hair of Arthur Carr was perfect! Both were of the same light brown color, and both had running through that color the same delicate golden tinge, brightly visible in the light, hardly to be detected at all in the shade.

Why had this extraordinary resemblance never struck him before? Perhaps because he had never examined Arthur Carr’s hair with attention until he had possessed himself of Mary’s bracelet, and had gone away to the country. Perhaps also because he had never yet taken notice enough of Zack’s hair to care to look close at it. And now the resemblance was traced, to what conclusion did it point? Plainly, from Zack’s youth, to none in connection with him. But what elder relatives had he? and which of them was he most like?

Did he take after his father?

Mat was looking down at the sleeper, just then; something in the lad’s face troubled him, and kept his mind from pursuing that last thought. He took the lock of hair from the pillow, and went into the front room. There was anxiety and almost dread in his face, as he thought of the fatally decisive question in relation to the momentous discovery he had just made, which must be addressed to Zack when he awoke. He had never really known how fond he was of his fellow lodger until now, when he was conscious of a dull, numbing sensation of dismay at the prospect of addressing that question to the friend who had lived as a brother with him, since the day when they first met.

As the evening closed in, Zack woke. It was a relief to Mat, as he went to the bedside, to know that his face could not now be clearly seen. The burden of that terrible question pressed heavily on his heart, while he held his comrade’s feeble hand; while he answered as considerately, yet as briefly as he could, the many inquiries addressed to him; and while he listened patiently and silently to the sufferer’s long, wandering, faintly-uttered narrative of the accident that had befallen him. Towards the close of that narrative, Zack himself unconsciously led the way to the fatal question which Mat longed, yet dreaded to ask him.
