Attempt to kill James I (9,4)

I believe the answer is:

gunpowder plot

(Other definitions for gunpowder plot that I've seen before include "Sixteen zero five" , "Guy Fawkes's scheme" , "Guy's planning" , "Guy Fawkes' conspiracy" , "Thwarted conspiracy of 1605" .)

I've seen this clue in The Guardian.
