'Yesterday? Then you knew last evening. Mother was right.'
'I did not know. I don't know now. It seems incredible that two men could be so much alike, but, on the other hand, it seems equally incredible that, under the circumstances, it could have been he.'
'Under the circumstances? What were the circumstances?'
'That I decline to say. I must ask you to take my word for it that the circumstances under which I saw this man make it practically impossible that it could have been he.'
'Did he see you?'
'He did not.'
'Did you try to speak to him?'
'I had no chance.'
'Did you find out where he lives, or anything at all about him?'
'I did this: I found a man who knows him, and who, I have reason to believe, will bring me face to face with him at a very early date.'
