I then read Biggles. Biggles was a great favourite for boys, and I took up a weekly magazine, called Modern Boy. How old was I when I started Modern Boy, I wonder? Possibly eight? And in Modern Boy, there were lots of adventures, week by week, that took place all over the world. For instance, there was a chap with his kanakas, scouring the Pacific that I quite enjoyed.

But what I most enjoyed were the stories of a man calling himself Murray Leinster... no, he was called... sometimes Leinster, but, generally Murray Roberts. He wrote stories about Captain Justice. Captain Justice, my hero! My hero. Captain Justice had a floating island called Station A that was in the middle of the Atlantic. And Captain Justice would be called upon when there was any global problem too big for the USA and Britain to solve. Send for Captain Justice. And Captain Justice had a wonderful airship, called the Flying Cloud. And the Flying Cloud was the invention of a Professor Flaznagel, and Flaznagel was one of Captain Justice's team. And this wonderful Flying Cloud, you could pull a lever and it would become totally invisible. Wonderful! Wonderful!

So, Justice had a great deal of problems on his hands. For instance, it turned out that the Sargasso Sea was full of frogmen, who were six feet high and very nasty indeed, and Captain Justice had to defeat them.

And eventually – I think it was possibly Murray Roberts' last Captain Justice book – he wrote a novel called, The World in Darkness. I collected all of his books – they were 4d, four pence – and I gave them to a science fiction museum on the Continent.
