In Edward Marston's The King's Evil, p18, we find the following passage on the Great Fire of London in 1666:
'And how long did it rage?' 'Four days.' Jacob sucked in air through his few remaining teeth. 'Four long, terrible days. It would still be burning if the wind had not dropped on Wednesday. Rain fell and slowed the blaze down. They were able to fight it properly for the first time. Rows of houses were blown up with dynamite to make fire breaks.[...]'
Well done the time-travelling Alfred Nobel, eh? And no, this isn't supposed to be AU. Poor show, Mr Marston.
