We’ve all seen films where someone’s father or husband turns out to be a secret agent – True Lies and Spy Kids spring to mind.  We’ve heard of young people being spies – MI High, for example.  But I’ve never come across one where the spy is the grandma.

If you were writing this story, would you have it true-to-life, with the grandma having to rest occasionally, or take medicine, or go to the hospital for blood transfusions every month?  Or would the grandma be healthy?  Would grandpa know?  Perhaps they are both spies?  Or grandpa is kidnapped and grandma has to rescue him, thus spoiling her 50-year cover.
