Bastable was mystified, my grandfather was mystified, and I must confess to being mystified myself -though such speculations are supposed to be my stock-in-trade. I have used, quite shamelessly, in novels of my own, some of the ideas found in the book I've named The Warlord of the Air, and, indeed, one or two of the characters (specifically Una Persson, who appears in The English Assassin) have been 'lifted'. Perhaps Miss Persson will some time come across one of these books. If she does, I very much hope she will pay me a visit - and possibly give me an answer to the mystery of Oswald Bastable. I assure you that the moment she does, I shall pass the news on!
