Going Like a Bomb

Being used to a diet of organised crime, drug manufacturing, smuggling, and dealing in all its many forms, and attacks on them by assassins working for the Russian, and the Chinese, governments, all as a result of their association with Chief Inspector Macdonald, Sinead Grogan and Christopher Caine had been afraid they might find life boring when they gave up working for Macdonald and became private detectives, instead but they were wrong.
In their youth they had been into banning the bomb, not making them, but when a group of determined former CND women were faced with the prospect of an oil well being developed on the outskirts of their village things changed.
Miss Matches advanced science classes were always well attended, because she taught her students how to make explosives out of things they could find growing wild in their gardens.
Very useful that, if you were trying to make a bomb to blow up an oil well.
Not so useful if you were private investigators Grogan and Caine intent on stopping the women from carrying out their plans.
