'Yes; at last.'

'We have waited for it a good many years; you and I.'

'That is so.'

This was platitudinous. I felt that if she had nothing more original to say I should have to ask her to excuse me if I gave my attention to matters which pressed. Her words, her voice, her very neighbourhood, seemed to have a singular effect upon my nervous system. It was as if I were ashamed. In some curious way, it was as if I were afraid of her. I wanted to take her in my arms; to hold her to me; to find strength in her sweet tenderness; for it was strength I needed. But I was conscious of an awkward inability to do as I had done a hundred times before--ay, a thousand. A shadowy something seemed to have interposed itself between us, as her own quick sight perceived.

'What is the matter with you, Douglas?'

The question took me aback. I looked up at her with a start, experiencing an unwonted difficulty in meeting her inquiring glances.

'The matter? Why?'

'You seem changed.'

'Changed? It's your fancy.'

'It's a very vivid fancy then. I noticed it first the night you dined with us.' On the afternoon of that day I had first seen the sleeping man. Are there any detectives like the eyes of the woman who loves? 'It has grown more perceptible since. Until now it sits upon you in a guise so that you seem transformed.'
