In 1854, English aristocrat Roger Tichborne disappeared at sea. Twelve years later, a butcher from Wagga Wagga, Australia, claimed he was the long-lost heir. In this week's episode of the Futility Closet podcast, we'll tell the sensational story of the Tichborne claimant, which Mark Twain called "the most intricate and fascinating and marvelous real-life romance that has ever been played upon the world's stage."

We'll also puzzle over why family businesses are often more successful in Japan than in other countries.

This week's lateral thinking puzzle is from Paul Sloane and Des MacHale's 2014 book Remarkable Lateral Thinking Puzzles. There's a fuller explanation (with spoilers!) in Dan Lewis' Now I Know newsletter.
