She could not be sure of what she suspected between them. She scorned to make herself assured. She could not stoop to the miserable method necessary to the acquirement of dread certainty. And yet "she was walking every day with bare feet on a burning pavement without feeling the burn."

Passing with noiseless step before a house-wall arising like a screen before her path, she paused for a moment to enjoy one last gaze at the pageant of sea and sky in the light of waning day. In this brief time the sound of her own name spoken by low voices behind the ruined wall forced themselves upon her hearing. They were those of her stepmother and the man Danielson.

Two phrases interchanged, but they told Helen all. She could never again indulge in the misery of doubt.

She stood for an instant as if overtaken by the lava flow that had devastated the homes of seventeen centuries ago surrounding her. The one despairing, driving impulse was to steal away unseen by the woman who dishonored her dear father's name. Helen thought she had rather fall down and die and become embedded with the dust of ages than go back to face Mrs. Carstairs and let her know she had found her out.

As the couple, without discovering her neighborhood, moved in an opposite direction, Mr. Carstairs' daughter took wings to her feet and flew to pick up Eulalie and find the cab they had left before the Hotel Diomed. The maid, sluggish though were the workings of her mental part, saw that her mistress had had a fright, and blamed herself for losing sight of her. Helen's cheeks were white, her hands shook as though palsied, as she sprang into the cab and bade the man drive fast, fast, back toward the town. She wished, at all events, to avoid being caught up with or passed by the pair, who could not at that hour linger much longer within the enclosure.

During the long joggling drive through interminable stony streets, encumbered by the populace of the Neapolitan suburbs, performing their domestic avocations out of doors, she came to a desperate conclusion. She was of age sufficiently mature to act for herself. She could not, would not, give her reasons to her father. But she would carry out her recent determination to leave the yacht at once, forfeit the price that had been paid her to be an infamous blind, and, at any risk, sever her present connection with Mrs. Carstairs.

Helen possessed the American woman's promptitude in action. She drove with Eulalie to an hotel formerly frequented with her father, engaged a room for the night, and sent the maid to the yacht with a note requesting Miss Bleecker to come to her. The interview resulting with her estimable chaperon was perhaps one of the most painful of her experience. The lady, to whom she gave in explanation of her resolve a bare statement that she could no longer endure the trial of life with her stepmother, exhausted herself in remonstrance and reproach. She pointed out to Helen that the money from her father could still be, and no doubt would be, withdrawn upon announcement of Miss Carstairs' extraordinary move. Helen declared that, well aware of this fact, she was prepared to live on the small income coming to her from her mother's estate. Miss Bleecker reminded her that her father was in evidently wretched health, and that no whim or temper should stand between him and his daughter's attendance at his side. Helen, blushing scarlet, with tears in her eyes, recalled to Miss Bleecker that she had not been allowed access to her father's own cabin since they had been together on the cruise, and that, furthermore, he did not appear to want her. Miss Bleecker called Heaven to witness that she had no patience with family jars, had no axe to grind on her own account, but that if Helen persisted in her wilful determination she should feel it her bounden duty not to forsake poor Mrs. Carstairs if wanted to remain.

That evening, between nine and ten, Mrs. Carstairs called upon Miss Carstairs, but was not received. Helen sent back, in a hotel envelope, her stepmother's card, across which she had written these words:

"I happened to be at Pompeii this afternoon, but no other than myself shall know under what circumstances you also were there. It is enough that we must part."

Next day Mrs. Carstairs announced to her guests that they were sailing for Sicily, and as Miss Carstairs did not desire to go farther South, she had decided to return by train to the Riviera, to visit her friend, Miss Winstanley, at Cannes, and would rejoin the "Sans Peur" later, somewhere in the Mediterranean. Then the "Sans Peur" steamed gallantly away, bearing Miss Bleecker, now installed as companion to the owner's lady, and Mr. Carstairs, keeping his cabin, it was said, with a bad attack of some trouble undeclared.
