"It was the disappearance of the airmen that first set me thinking. Of course, everyone said that they had fallen into the sea, but that did not satisfy me at all. First, there was Verrier in France; his machine was found near Bayonne, but they never got his body. There was the case of Baxter also, who vanished, though his engine and some of the iron fixings were found in a wood in Leicestershire. In that case, Dr. Middleton, of Amesbury, who was watching the flight with a telescope, declares that just before the clouds obscured the view he saw the machine, which was at an enormous height, suddenly rise perpendicularly upwards in a succession of jerks in a manner that he would have thought to be impossible. That was the last seen of Baxter. There was a correspondence in the papers, but it never led to anything. There were several other similar cases, and then there was the death of Hay Connor. What a cackle there was about an unsolved mystery of the air, and what columns in the halfpenny papers, and yet how little was ever done to get to the bottom of the business! He came down in a tremendous vol-plane from an unknown height. He never got off his machine and died in his pilot's seat. Died of what? 'Heart disease,' said the doctors. Rubbish! Hay Connor's heart was as sound as mine is. What did Venables say? Venables was the only man who was at his side when he died. He said that he was shivering and looked like a man who had been badly scared. 'Died of fright,' said Venables, but could not imagine what he was frightened about. Only said one word to Venables, which sounded like 'Monstrous.' They could make nothing of that at the inquest. But I could make something of it. Monsters! That was the last word of poor Harry Hay Connor. And he DID die of fright, just as Venables thought.
