I remarked that, if she had ‘gone for’ Sir Runan, she had only served him right.

Then I tried to restore her self-respect by quoting the bearded woman’s letter.

I pointed out that she had been Lady Errand, after all.

This gave Philippa no comfort.

‘It makes things worse,’ she said. ‘I thought I had only got rid of my betrayer; and now you say I have killed my husband. You men have no tact.’

‘Besides,’ Philippa went on, after pausing to reflect, ‘I have not bettered myself one bit. If I had not gone for him I would be Lady Errand, and no end of a swell, and now I’m only plain Mrs. Basil South.’ Speaking thus, Philippa wept afresh, and refused to be comforted.

Her remarks were not flattering to my self-esteem.

At this time I felt, with peculiar bitterness, the blanks in Philippa’s memory. Nothing is more difficult than to make your heroine not too mad, but just mad enough.

Had Philippa been a trifle saner, or less under the influence of luncheon, at first, she would either never have murdered Sir Runan at all (which perhaps would have been the best course), or she would have known how she murdered him.

The entire absence of information on this head added much to my perplexities.
