'The news of the discovery of Magda Braile's body had just come in and I had to get out to the spot as quickly as possible.’ 'So I supposed,’ Andrew said. ‘But I didn't follow you out for some time. I found that address book an interesting thing to study.’ ‘Because of the typist?’ ‘Mrs Wale? Yes. I went to see her, you know. I suppose we were both interested in her for the same reason.’ ‘Because of the possibility that she'd typed Amory's manuscripts for him?’ ‘Ah yes, I remember now that's what she told me you'd wanted to know. But I was curious actually as to whether she'd typed anything for Mrs Amory. Perhaps I ought to explain that.’ The big man massaged his knees with his heavy hands. ‘Go ahead,’ he said.
