In this instalment of the series, Sharpe and his men are needed to capture a french fortress and then blow it up with the aid of the disfigured but kind hearted explosives expert Septimus Pyecroft. A pretty easy job for the dashing Richard Sharpe one would think, but there is more to this mission than meets the eye. Not only must Sharpe and his men face the french army, but they must also discover the identity of the traitor within their midst. In this episode, Sharpe must also face his own personal battle, as his mind strays from the job at hand to his new wife, who has become increasingly bored with camp life and has started taking a worrying interest in one Clarence Shellington, a poet and reporter for a London newspaper. Along with this poor Sharpe has to deal with Rifleman Harris who has been wrongly accused of murdering some gypsies who have been hanging around the British camp and thus is in serious trouble with the Provost Marshall. Ultimately it is up to Major Sharpe to complete his mission against the French and for Rifleman Harris to protect Sharpe's wife from the advances of Mr Shellington. For fans of the Sharpe series, this will all be familiar ground but for others, this is a good introduction to the series as this episode has it all, fighting, intrigue, explosions and a good healthy dose of Sean Bean.
