S.H. Courtier
‘Here’s a problem you might work out in your spare time. It is something I want to use in a story that is buzzing in my mind and I can’t get on with it until I solve the problem. The hero wants to hide a small cylinder somewhere in a car. The cylinder holds important documents—secret documents. Now where and how could he hide the cylinder in a car so that even expert mechanics fail to spot it? In the story, when it is shown where the cylinder was hidden, the searchers will say, “Heavens, I should have thought of that myself.” And I want the readers of the story to say that too. I’d be awfully grateful for your help.’ (From a letter by Courtier to his brother-in-law, Alan George, 3/3/73.)
