One of the Nobel prize winner’s most clumsily written novels, it nonetheless carries a timeless warning about how a leader able to manipulate the citizenry could quickly erode democracy’s fragile stability. The totalitarian takeover that Lewis created as fiction in 1935 is a graphic echo of Patrick Henry’s (or Wendell Phillips’s) reminder about the price of liberty being eternal vigilance.
