Dear Mr Cornwell, I seem to recollect somewhere that you wrote a description of the Viking era and lifestyle, probably as a foreward or brief essay, in which you rounded up the piece by saying that we as a culture were fascinated by the Vikings because they were essentially free spirits. Unfortunately I cannot remember where I read this, but would love to find and read it again. If this rings any bells, please can you point me in the right direction. Keep up the good work, Tom.
