For years I've wanted to write a book about mummies, and had been following the science of mummy CT scans when the premise for 'The Keepsake' occurred to me: what if an 'ancient' mummy turns out to have a bullet in its leg? How does a modern murder victim get turned into a mummy?
My most successful books, the ones that I feel the strongest about, are the ones that started with a premise that for me was deeply emotional.
