In Martin Cruz Smith’s thriller Havana Bay, a visiting American gets caught in a plot against Fidel Castro, but then discovers the plot was organised by Castro himself. Castro is well aware of the growing discontent with his rule even in the top circle of functionaries around him, so every couple of years he orders a secret agent to organise a plot to overthrow him, in order to root out the disloyal functionaries. Just when the plot is supposed to be enacted, the malcontents are arrested and liquidated. And that’s the first thing I would do to secure my reign if I ruled the world—God himself does it in GK Chesterton’s The Man Who Was Thursday, so I’d be in a good company.
