McNeile, Herman Cyril: The Third Round. v1. 30 Dec 2015
 

Herman Cyril McNeile, MC (28 September 1888 – 14 August 1937), commonly known as Cyril McNeile and publishing under the name H. C. McNeile or the pseudonym Sapper, was a British soldier and author. Drawing on his experiences in the trenches during the First World War, he started writing short stories and getting them published in the Daily Mail. As serving officers in the British Army were not permitted to publish under their own names, he was given the pen name "Sapper" by Lord Northcliffe, the owner of the Daily Mail; the nickname was based on that of his corps, the Royal Engineers.

Excerpt
In endeavouring to put before the public for the first time the truth concerning the amazing happenings of the summer of 1927, I feel myself to be at a disadvantage. In the first place I am no storyteller: so maybe my presentation of the facts will fail to carry conviction. Nay, further: it is more than likely that what I am about to write down will be regarded as a tissue of preposterous lies. And yet to those who condemn me offhand I would say one thing. Take the facts as you know them, and as they appeared in the newspapers, and try to account for them in any other way. You may say that in order to write a book—gain, perhaps, a little cheap notoriety—I have taken the ravings of a madman around which to build a fantastic and ridiculous story. You are welcome to your opinion. I can do no more than tell you what I know: I cannot make you believe me.
