He is rescued from disgrace by General Sir David Baird, an old comrade from India, who needs a "disposable" man for a mission in Copenhagen. An army is travelling to the Danish capital to enforce British policy, but unless Sharpe can complete the mission against enemies as subtle and clever as any he has ever faced, that army will meet disaster.
