Flashman by George Macdonald Fraser

Coward, scoundrel, lover and cheat, but there is no better man to go into the jungle with. Join Flashman in his adventures as he survives fearful ordeals and outlandish perils across the four corners of the world.

Can a man be all bad? When Harry Flashman's adventures as the reluctant secret agent in Afghanistan lead him to join the exclusive company of Lord Cardigan's Hussars and play a part in the disastrous Retreat from Kabul, it culminates in the rascal's finest - and most dishonest - turn.
