The Man Who Knew Everything: The Most Valuable Man Alive

Philip Merriwether has never impressed anyone. He drifts through life unnoticed, forgetful, and harmless. Then something changes. Suddenly, every fact ever written seems to live inside his head, waiting to be spoken. Trivia becomes certainty. Questions become answers before they’re finished. What begins as a windfall on a television quiz show turns into something far more serious when his knowledge strays into territory no civilian should ever possess.

Governments do not tolerate loose secrets. When Philip repeats classified information on live television, the celebration ends overnight. Armed agents appear at his door. Military leaders demand explanations. The President himself wants to know how a forgotten clerk now holds the blueprints of national defense in his memory. Philip never meant to betray anyone. He simply answers questions. But when knowing everything includes weapons, troop locations, and covert plans, even innocence becomes a threat.

What makes this story unforgettable is the quiet transformation at its center. A man once pitied for his blank mind must now live with a mind too full to control. The very thing that once made him invisible becomes the reason he can never disappear again. His dilemma is immediate and human: when knowledge cannot be contained, what responsibility comes with it? And who gets to decide how it is used?

Randall Garrett built his reputation on wit, precision, and an ability to twist speculative ideas into sharp satire. His fiction appeared in Astounding Science Fiction, Analog, Galaxy, and The Magazine of Fantasy & Science Fiction. He collaborated frequently with Robert Silverberg and Harlan Ellison, and he is best remembered for the Lord Darcy stories, which blended alternate history with detective fiction. In this tale, Garrett uses humor to explore a far more unsettling possibility—what happens when information becomes a weapon simply because someone remembers it.
