He stopped short and made a face as though he had bitten his tongue. Then he grinned sheepishly as the flush came into his cheeks.

"Sorry, old thing," he mumbled. "Stupid of me, wasn't it? I see what you mean, of course. When Air Vice Marshal Bostworth doesn't see us return from a two hour mystery patrol over this area, he'll jolly well send out search planes, eh?"

"He'd jolly well better!" Dave grunted and fished for the chocolate bars he always carried. "Or I'll punch him right on the nose if I ever meet up with him again. He got us into this, and he can get us out! Here, have a hunk of chocolate. And don't chew with your mouth open. It's not nice, and it makes me nervous."

Freddy Farmer shrugged when he could think of no fitting retort to that one. However, he accepted one of the bars of chocolate, and both boys fell to eating and silently staring out over the expanse of rolling blue water that seemed to touch no land in any direction.


[CHAPTER FOUR]
Satan Over Singapore

Exactly five hours later the two boys were still staring out across the rolling blue swells, and in between times they had searched and researched the blazing China Sea skies with their tired eyes. But from then until now they had seen nothing to bring joy or alarm to their hearts. No planes or ships had appeared, and although they had kidded and horsed around to keep each other's spirits at a high level, tiny fears, and dreads, and doubts, were little by little boring deeper into their thoughts. For five hours neither had seen the slightest sign of anything that might mean rescue. And for five solid hours each had expected the mysterious submarine to rise to the surface again and really finish them off. After all, they had been shot down by the undersea boat's guns for reasons they still couldn't figure out. But just to be shot down and left floating alive was something else again. That is, unless the crew and officers of that strange submarine were of the belief that they had died.

Licking his dry lips, Dave half turned in the seat and shot a quick glance back at Freddy Farmer. There was a set smile on the English youth's lips, but the tightness at the corners of his eyes, and a faint line of worry that creased his forehead told that the youth was struggling inwardly to keep control of his jangled nerves and not go haywire.

"I think I forgot to ask you," Dave said. "Just how did you like your visit to Singapore, anyway?"

"Top-hole!" Freddy said with a forced smile. "So ... so stimulating, and educational, you know. Fact is, I don't believe I'll ever forget it. One of the milestones in my life."
