"Where's the other man?" asked the warder, in a low voice.
"He's upstairs in the back room."
The warder stepped out of the door and looked left and right.
Coming up from Princetown was a big, grey car.
"Put down your paint pot," he said.
His voice was shaking with excitement.
"I am going upstairs.When that car comes abreast of the gate, ask no questions and jump into it.Get down into the bottom and pull a sack over you, and do not get up until the car stops."The blood rushed to John Lexman's head, and he staggered.
"My God!" he whispered.
"Do as I tell you," hissed the warder.
Like an automaton John put down his brushes, and walked slowly to the gate.The grey car was crawling up the hill, and the face of the driver was half enveloped in a big rubber mask.Through the two great goggles John could see little to help him identify the man.As the machine came up to the gate, he leapt into the tonneau and sank instantly to the bottom.As he did so he felt the car leap forward underneath him.Now it was going fast, now faster, now it rocked and swayed as it gathered speed.He felt it sweeping down hill and up hill, and once he heard a hollow rumble as it crossed a wooden bridge.
He could not detect from his hiding place in what direction they were going, but he gathered they had switched off to the left and were making for one of the wildest parts of the moor.Never once did he feel the car slacken its pace, until, with a grind of brakes, it stopped suddenly.
"Get out," said a voice.
John Lexman threw off the cover and leapt out and as he did so the car turned and sped back the way it had come.
For a moment he thought he was alone, and looked around.Far away in the distance he saw the grey bulk of Princetown Gaol.It was an accident that he should see it, but it so happened that a ray of the sun fell athwart it and threw it into relief.
He was alone on the moors! Where could he go?
He turned at the sound of a voice.
He was standing on the slope of a small tor.At the foot there was a smooth stretch of green sward.It was on this stretch that the people of Dartmoor held their pony races in the summer months.
There was no sign of horses; but only a great bat-like machine with out-stretched pinions of taut white canvas, and by that machine a man clad from head to foot in brown overalls.
John stumbled down the slope.As he neared the machine he stopped and gasped.
"Kara," he said, and the brown man smiled.
"But, I do not understand.What are you going to do!" asked Lexman, when he had recovered from his surprise.
"I am going to take you to a place of safety," said the other.
"I have no reason to be grateful to you, as yet, Kara," breathed Lexman."A word from you could have saved me.""I could not lie, my dear Lexman.And honestly, I had forgotten the existence of the letter; if that is what you are referring to, but I am trying to do what I can for you and for your wife.""My wife!"
"She is waiting for you," said the other.
He turned his head, listening.
Across the moor came the dull sullen boom of a gun.
"You haven't time for argument.They discovered your escape," he said."Get in."John clambered up into the frail body of the machine and Kara followed.
"This is a self-starter," he said, "one of the newest models of monoplanes."He clicked over a lever and with a roar the big three-bladed tractor screw spun.
The aeroplane moved forward with a jerk, ran with increasing gait for a hundred yards, and then suddenly the jerky progress ceased.
The machine swayed gently from side to side, and looking over, the passenger saw the ground recede beneath him.
Up, up, they climbed in one long sweeping ascent, passing through drifting clouds till the machine soared like a bird above the blue sea.
John Lexman looked down.He saw the indentations of the coast and recognized the fringe of white houses that stood for Torquay, but in an incredibly short space of time all signs of the land were blotted out.
Talking was impossible.The roar of the engines defied penetration.
Kara was evidently a skilful pilot.From time to time he consulted the compass on the board before him, and changed his course ever so slightly.Presently he released one hand from the driving wheel, and scribbling on a little block of paper which was inserted in a pocket at the side of the seat he passed it back.
John Lexman read:
"If you cannot swim there is a life belt under your seat."John nodded.
Kara was searching the sea for something, and presently he found it.Viewed from the height at which they flew it looked no more than a white speck in a great blue saucer, but presently the machine began to dip, falling at a terrific rate of speed, which took away the breath of the man who was hanging on with both hands to the dangerous seat behind.
He was deadly cold, but had hardly noticed the fact.It was all so incredible, so impossible.He expected to wake up and wondered if the prison was also part of the dream.
Now he saw the point for which Kara was making.
A white steam yacht, long and narrow of beam, was steaming slowly westward.He could see the feathery wake in her rear, and as the aeroplane fell he had time to observe that a boat had been put off.Then with a jerk the monoplane flattened out and came like a skimming bird to the surface of the water; her engines stopped.
"We ought to be able to keep afloat for ten minutes," said Kara, "and by that time they will pick us up."His voice was high and harsh in the almost painful silence which followed the stoppage of the engines.
In less than five minutes the boat had come alongside, manned, as Lexman gathered from a glimpse of the crew, by Greeks.He scrambled aboard and five minutes later he was standing on the white deck of the yacht, watching the disappearing tail of the monoplane.Kara was by his side.
"There goes fifteen hundred pounds," said the Greek, with a smile, "add that to the two thousand I paid the warder and you have a tidy sum-but some things are worth all the money in the world!"
