Now that the war and the problems of war are a thing of the past, I think I may safely venture to reveal to the world the part which Miss Felicity Lemon, one-time confidential secretary to my old friend Hercule Poirot, played in a moment of national crisis.

Between us, Miss Lemon and I had worked with Poirot for many years, but had never actually met each other, until the extraordinary events of the summer of 1943 finally brought us together.  Whilst investigating some anomalies amongst my dear late friend’s confidential papers, we found ourselves drawn into a conspiracy involving the highest levels of allied military and civilian intelligence.

Miss Lemon is one of the most unusual people that I know, but it was her labyrinthine filing system that provided the means to expose the conspiracy, thereby  preventing a potentially catastrophic setback to the prosecution of the War.

When I showed my narrative to Miss Lemon, she read it straight through in one sitting. At the end, she removed her glasses and handed it back to me without a word.

I took that to be a sign of approval.
