Note 1
"I decided that now there was a war on an up-to-the-minute spy story was the thing, so on the 6th. September (1939), I sat down to write 'The Scarlet Impostor' ... ... ... ... ... ... By working most days from 10.00am to 2.00am the following morning, I got it finished on the 19^th October. 172,000 words in seven weeks, and one of the best books I have ever written."
