Dear Mr Cornwell, During an email conversation with some friends we somehow got on to the topic of your books, which two of us have read repeatedly, a question came up about the Sharpe novels, so I jumped onto wikipedia and found your riddle – “Take you out, put me in and a horse appears in this happy person!” for Sharpe’s father, its been maddening me since, has anyone guessed this correctly? Have you got any others clues?
