‘I wouldn’t mind how soon I went to bed, Mr Parkes. What do you feel like?’

‘I don’t feel sleepy,’ the other returned, and then, after a pause: ‘I don’t mind confessing I am not quite easy about Sir William. I would be glad he had returned.’

‘You’re afraid—of what you were saying?’

‘I am. I don’t deny it. I feel apprehensive.’

‘Supposing we were to get a couple of lanterns and have a walk round outside?’

The butler considered this suggestion.
