The goldfish were the first to vanish. Every so often, a few would go missing overnight from the office’s tiny outdoor pond. But goldfish were cheap, so no one in the building—an environmental nonprofit in the bustling, sweaty center of Colombo, Sri Lanka—bothered investigating.
Then the dragon koi began to disappear. Lustrous and ethereal, each of these whiskered Japanese carp cost around 10,000 Sri Lankan rupees, or $65. In a fit of extravagance, the building’s landlord had bought 10. Soon, he had seven. Then three.
Panicked, the landlord installed four security cameras to catch the thief. The pond rested at the end of a narrow driveway surrounded by tall concrete walls, so whoever was swiping the carp had either a key or the superhuman ability to bound up nearby roofs and drop in undetected. The landlord couldn’t imagine what kind of person would steal a fish, but he was eager to find out.
