'My name is Johnson. I—used to live in New York.'

'Where do you live now, Mr Johnson?' asked Waterall.

The bearded man hesitated again. 'Algiers,' he said.

Mr Birdsey was inspired to help matters along with small-talk.

'Algiers,' he said. 'I have never been there, but I understand that it is quite a place. Are you in business there, Mr Johnson?'

'I live there for my health.'

'Have you been there some time?' inquired Waterall.

'Five years.'

'Then it must have been in New York that I saw you, for I have never been to Algiers, and I'm certain I have seen you somewhere. I'm afraid you will think me a bore for sticking to the point like this, but the fact is, the one thing I pride myself on is my memory for faces. It's a hobby of mine. If I think I remember a face, and can't place it, I worry myself into insomnia. It's partly sheer vanity, and partly because in my job a good memory for faces is a mighty fine asset. It has helped me a hundred times.'

Mr Birdsey was an intelligent man, and he could see that Waterall's table-talk was for some reason getting upon Johnson's nerves. Like a good host, he endeavoured to cut in and make things smooth.
