'Why did he tell you?'

'Because he needed me as an accomplice. He wanted my help. It was I who got Ogden away that day. Sam overheard me giving money and directions to him, telling him how to get away from the school and where to go, and he gathered—correctly—that I was in the same line of business as himself. He suggested a partnership which I was unable to accept.'

'Why?'

'Our objects were different. My motive in kidnapping Ogden was not to extract a ransom.'

She blazed out at me in an absolutely unexpected manner. Till now she had listened so calmly and asked her questions with such a notable absence of emotion that the outburst overwhelmed me.

'Oh, I know what your motive was. There is no need to explain that. Isn't there any depth to which a man who thinks himself in love won't stoop? I suppose you told yourself you were doing something noble and chivalrous? A woman of her sort can trick a man into whatever meanness she pleases, and, just because she asks him, he thinks himself a kind of knight-errant. I suppose she told you that he had ill-treated her and didn't appreciate her higher self, and all that sort of thing? She looked at you with those big brown eyes of hers—I can see her—and drooped, and cried, till you were ready to do anything she asked you.'

'Whom do you mean?'

'Mrs Ford, of course. The woman who sent you here to steal Ogden.
The woman who wrote you that letter.'

'She did not write that letter. But never mind that. The reason why I wanted you to come here was to warn you against Sam Fisher. That was all. If there is any way in which I can help you, send for me. If you like, I will come and stay at the house till Mr Abney returns.'

Before the words were out of my mouth, I saw that I had made a mistake. The balance of her mind was poised between suspicion and belief, and my offer turned the scale.
