Goodreads asked Elizabeth Buchan:

Where did you get the idea for your most recent book?

Elizabeth Buchan My second novel, Light of the Moon, was about an undercover agent going into wartime France. After it was published, I was contacted by someone who became a great friend who used to work in the undercover SOE. Over the years, I have listened to her talking about her work and decided I had to write another novel about the men and women who operated in these shadowy areas... thus I Can't Begin to Tell You took shape.
