Tracing these developments through many of the past century’s major conflagrations, Dimsdale narrates how when World War II erupted, governments secretly raced to develop drugs for interrogation.

Nobel laureates, university academics, intelligence operatives, criminals, and clerics all populate this shattering and dark story – one that hasn’t yet ended.
