The first person that Anthony saw as he alighted from his train on the following afternoon was Superintendent Battle. His face broke into a smile.
‘I’ve returned according to contract,’ he remarked. Did you come down here to assure yourself of the fact?’
Battle shook his head.
‘I wasn’t worrying about that, Mr Cade. I happen to be going to London, that’s all.’
You have such a trustful nature, Battle.’
‘Do you think so, sir?’
‘No. I think you’re deep-very deep. Still waters, you know, and all that sort of thing. So you’re going to London?’
I am, Mr Cade.’
I wonder why.’
The detective did not reply.
