Synopsis by Hal Erickson
Steed (Patrick MacNee) Purdey (Joanna Lumley) and Gambit (Gareth Hunt) go undercover in one of the seamier neighborhoods of London. The Reason? Several prominent governmnet officials, including a friend of Steed's, have turned up dead. It turns out that someone is using disguised derelicts to replace the dead officials. The real trouble begins when the identical doubles for Gambit and Purdey show up (though it does permit Purdey the plum acting assignment of doubling for her own double).
