The Gunpowder Plot - Fawkes is Arrested

Government officials found out that a Catholic agitator was renting the house adjacent to the House of Lords.  When King James heard this, and also learned that an unusual amount of firewood was located in an abnormal place, he ordered a second search of the area.

Had the powder been set off, the explosion would have been massive.  Instead, the searching guards found Fawkes and his thirty-six barrels.
