Everybody around him at Longwood wrote their accounts of Napoleon's exile, but until now we have not heard from the man himself! Only joking! This is a work of fiction!
Some time ago I was in correspondence with James Hartley about the book he was then writing on Napoleon and St. Helena. It turned out to be a rather long labour of love?, and James has now decided to publish it on Kindle. I understand that it is going live tomorrow, which happens to be Napoleon's 248th birthday!
