I read GK Chesterton’s story collection The Man Who Knew Too Much, and it was a lifesaver. I picked this book on instinct right before I took off on a flight. When I was doing my final packing the morning of my trip, none of the books on my nightstand felt right. All the books at the airport looked dumb. It was a crisis. Then I remembered Project Gutenberg. I skimmed through some of the top/popular lists, clicked on some names I recognized, and a few seconds later I had a handful of options ready for travel. A good collection of fun, cynical mysteries, usually with some laconic or mordant humor. There’s usually some corruption at the heart of things. If you ever find yourself in a pinch, Gutenberg has you covered.
