Sharpe's options regarding his wife.
I've thought about what Sharpe could have done regarding his wife, Jane.
He could have sold her into slavery in the Ottoman empire. It was still legal during the time period to traffic in Caucasian slaves. In fact, they were still trading in Caucasian women illegally but without consequences during the first world war. A white aristocratic European women would have brought in serious money, several hundred pounds at least.
He also could have turned her back over to Sir Henry Simmerson. Doubtless Sir Henry missed his favorite home entertainment system and would have been glad to take her back.
Of course either would have damaged Sharpe's hero credentials.
