Picture this: it's the not-too-distant future, and astronomers pick up a persistent radio signal from an asteroid. This isn't your average space static. It's a complex, repeating pattern—a 'wail'—that defies all translation. Earth is thrown into a mix of scientific excitement and public panic. Governments form committees and debate endlessly, getting nowhere.

The Story

Frustrated by the official inertia, a group of private citizens takes matters into their own hands. Led by a determined man named Burke, they pool their resources to secretly build a spaceship. Their goal is simple yet insane: fly to the asteroid, Asteroidal Object 119, and find the source of the signal before anyone else. It's a race against time and the authorities. When they finally arrive, they discover the asteroid is artificial—a hollowed-out, ancient spaceship from another star. Inside, they find a fully automated base, still running, left behind by a long-gone alien civilization. The wailing signal was a distress beacon, a final message. The team must now figure out how to operate the alien technology, understand the purpose of the base, and confront the reason its builders are gone.

Why You Should Read It

What I love about this book is its spirit of can-do ingenuity. The heroes aren't super-soldiers or genius scientists; they're regular, smart people who just decide to go and see. Leinster captures that thrill of exploration perfectly. The mystery of the signal is genuinely intriguing, and the solution is satisfying. The alien base feels wonderfully strange and logical at the same time. It's also a snapshot of its time—written in 1960, it buzzes with that early-space-age optimism about private enterprise and human grit solving big problems.

Final Verdict

This is a perfect pick for anyone who loves classic, idea-driven science fiction. If you enjoy stories where the puzzle is just as important as the action, where characters use their wits instead of just lasers, you'll have a great time. It's for readers who appreciate the foundational tales of the genre, the ones that asked 'what if?' and then built a fun, solid adventure around the answer. A quick, entertaining read that proves some questions from the stars are just too compelling to ignore.
