I have simply loved every book of yours I have read, especially the Sharpe series. You must spend incredible amounts of time researching the circumstances and background, but my sense is you love it! Anyway, I noticed there is a BBC Video (staring Sean Bean) called “Sharpe’s Challenge.” I do not recall a book by that name, and the plot line (takes place in India after Waterloo) is not familiar. Is there a book on which this is based? Tom Keyser
