"My humble apologies for even thinking you could have come from elsewhere but Serrangi in Singapore," he said. "And the highest praise from myself and all my countrymen for so spectacular a flight. It is one I should not like to do in anything but a large plane. You are indeed a credit to the Luftwaffe."

"It was a small undertaking," Dave said with a boastful shrug. "Most any pilot and navigator in the Luftwaffe could have made it. I understand, then, that we have brought you good news, yes?"

The Jap general's lids contracted slightly, and the tiny gleam leaped into his eyes again.

"Serrangi always sends one good news," he said slowly. "That is why he is a wealthy man. There is one part that is not clear, however. The new location of Singapore Island's water supply. There has been a second underground reservoir constructed near Mandai?"

If it was a trick question meant to trap the boys, it fell flatter than yesterday's pancakes. Both Dave and Freddy shook their heads. And it was Freddy who answered the question ... truthfully.

"We know almost nothing of Singapore, General Kashomia," he said. "We have spent but one day and a night in the Singapore area. The good news that Serrangi gives to you, he did not give to us. It was but by a bit of good fortune that we were able to act as couriers."

If that news surprised General Kashomia he did not show it. However, his next words indicated that he wasn't getting all of the picture, yet.

"Strangers to Singapore?" he murmured. Then, "But not of course to Serrangi?"

"Yes!" Dave shot right back at him and got a little comfort and satisfaction out of the shadow of annoyed bewilderment that passed over the Jap's face.

"That is interesting," the son of Nippon said presently. "You will be good enough to explain, please? You are strangers to Singapore, and to Serrangi, also? Yet you fly here to where I wait, and place the means of a great military triumph in my hands? I have spent much time in Berlin, but I am afraid I shall never fully understand you Germans. The words you speak confuse me."
