‘I promise,’ said Miss Abbey.

‘It was on the night when the Harmon murder was found out, through father, just above bridge. And just below bridge, as we were sculling home, Riderhood crept out of the dark in his boat. And many and many times afterwards, when such great pains were taken to come to the bottom of the crime, and it never could be come near, I thought in my own thoughts, could Riderhood himself have done the murder, and did he purposely let father find the body? It seemed a’most wicked and cruel to so much as think such a thing; but now that he tries to throw it upon father, I go back to it as if it was a truth. Can it be a truth? That was put into my mind by the dead?’

She asked this question, rather of the fire than of the hostess of the Fellowship Porters, and looked round the little bar with troubled eyes.

But, Miss Potterson, as a ready schoolmistress accustomed to bring her pupils to book, set the matter in a light that was essentially of this world.

‘You poor deluded girl,’ she said, ‘don’t you see that you can’t open your mind to particular suspicions of one of the two, without opening your mind to general suspicions of the other? They had worked together. Their goings-on had been going on for some time. Even granting that it was as you have had in your thoughts, what the two had done together would come familiar to the mind of one.’

‘You don’t know father, Miss, when you talk like that. Indeed, indeed, you don’t know father.’

‘Lizzie, Lizzie,’ said Miss Potterson. ‘Leave him. You needn’t break with him altogether, but leave him. Do well away from him; not because of what I have told you to-night—we’ll pass no judgment upon that, and we’ll hope it may not be—but because of what I have urged on you before. No matter whether it’s owing to your good looks or not, I like you and I want to serve you. Lizzie, come under my direction. Don’t fling yourself away, my girl, but be persuaded into being respectable and happy.’

In the sound good feeling and good sense of her entreaty, Miss Abbey had softened into a soothing tone, and had even drawn her arm round the girl’s waist. But, she only replied, ‘Thank you, thank you! I can’t. I won’t. I must not think of it. The harder father is borne upon, the more he needs me to lean on.’

And then Miss Abbey, who, like all hard people when they do soften, felt that there was considerable compensation owing to her, underwent reaction and became frigid.

‘I have done what I can,’ she said, ‘and you must go your way. You make your bed, and you must lie on it. But tell your father one thing: he must not come here any more.’
