n's expression never changed. "And some are almighty
good," he said calmly. "Like Bradley. Soon as I knew he was on the case,
I reported to my superiors and we dropped the thing like a hot potato,
just to avoid being at cross-purposes. We knew that the Americans would
tip us off as soon as they had a definite answer."

The boys stared at Keaton-Yeats. "But you're a bank clerk!" Rick
exclaimed.

"He's also a British intelligence agent," Bradley said, grinning.
"That's why I insisted he come tonight. We've already informed the
British, through channels, that the heavy-water menace no longer exists.
Keaton-Yeats is here tonight to get the details."

"You chaps would be simply amazed at how much valuable information one
picks up in a bank," Keaton-Yeats said. "Astounding. Although I must say
having lads ask for golden mice is a bit unusual."

Scotty shook his head. "And you looked so innocent," he complained. "We
believed everything you said."

The young Englishman grinned. "I am innocent," he replied. "No woolly
little lamb could be more so. And I did tell you the blessed truth, you
know, even though I didn't mention I had a bit of a job to do as well as

"I'm astonished," Zircon admitted. "But get on with your story, Carl."

"Right. As I said, spies spy on each other. I contacted a French agent I
know, and in the course of having lunch with him I casually asked how
much he had paid for the information about an atomic pile. I was just
fishing, of course. Well, he took the bait. He leaped at it like a
striking tuna. I knew I had something then. From there on, it wasn't
hard to uncover the whole business, just by making contact with the
espionage agents of various countries."

The JANIG man wet his throat with another sip of coke. "And business is
just what it was. I can't say how long ago Long Shadow found out there
was heavy water in the Caves of Fear. I did find out that in his younger
days he was something of a scientist and that he explored the Korse
Lenken region thoroughly. That was shortly before the discovery of heavy
water in Lake Baikal. I think we can assume that he pieced the story
together and realized that the lake in the caverns had the same
