The telegram from Singapore was a coded message from Chahda, their friend from Bombay. (What he as doing in Singapore, none of them could imagine.) It was a big pile of numbers that looked like gokum until the island's brain trust had been over it. But they did go over it, and found a message --

Come both. Bad troubles. Am in danger. My boss, Carl Bradley, disappeared. Government will ask scientific father do special work. Must take. Get jobs, meet me Hong Kong Golden Mouse. Watch Chinese with glass eye, he dangerous. And beware long shadow. . . .

The message was an adventure getting ready to happen, was what if was. But what's to expect? This is a book called The Caves of Fear. It's a Rick Brant science-adventure story! Of course there are improbable puzzles and peculiar circumstances!
