I had only my own and the exertions of a few and trusted servants to rely upon, and it was therefore impossible for us to watch all the various backdoors leading out of England at once.

When I had finished my dinner I strolled down the Strand as far as Charing Cross Station.

Turner was to leave for St.
Petersburg that night by the mail-train, and I had some instructions to give him before his departure.

I found him in the act of attending to the labelling of his luggage, and, when he had seen it safely on the van, we strolled down the platform together.

I warned him of the delicate nature of the operation he was about to undertake, and bade him use the greatest possible care that the man he was to watch did not become aware of his intentions.
