In the autumn of 1605, Catholic conspirators believed they were about to strike a blow to the heart of the English state – but then a mysterious letter exposed their plan. In this second episode of our four-part series on the plot, Danny Bird speaks to historian John Cooper about the Gunpowder Plot’s dramatic collapse. They examine Fawkes’s arrest and forced confession, the grisly public trials and executions that followed, and how James VI & I turned the plot's failure into political dynamite – consolidating power and turning treason into an abiding warning to posterity.
