Had he known of her lying and prating she would not have remained an hour under his roof; but Mrs.Kebby was cunning enough to steer clear of such a danger in the most dexterous manner.

She had a firm idea that Berwin had, in her own emphatic phrase, "done something" for which he was wanted by the police, and was always on the look out to learn the secret of his isolated life, in order to betray him, or blackmail him, or get him in some way under her thumb.

As yet she had been unsuccessful.
Deeming her a weak, quiet old creature, Berwin, in spite of his suspicious nature, entrusted Mrs.Kebby with the key of the front door, so that she could enter for her morning's work without disturbing him.
