Extract: "Jim Maitland stopped dead in his tracks, and then with the instinct bred of many years he sought the cover of a neighbouring tree. In the country he had just come from he would not have given the matter a second thought-gun work was part of the ordinary day's round. But in London, especially in this part of London, it was a very different affair. The sound had come from the house in front of him-a house very similar to the one he had just left, save that it was not for sale. It was in darkness, but some kind of subconscious instinct told him that there had been a light in one of the upper windows a few seconds previously." Herman Cyril McNeile (1888-1937), commonly known as H. C. McNeile or Sapper, was a British soldier and author. Drawing on his experiences in the trenches during the First World War, McNeile's stories are either directly about the war, or contain people whose lives have been shaped by it. His thrillers are a continuation of his war stories, with upper class Englishmen defending England from foreigners plotting against it.
