Four agents have vanished, looking for each other, in Little Bazeley-by-the-Sea. Steed and Emma go in for the man who went in for the man who.... and meet the odd local landlord, blacksmith and vicar. Are they more than they seem?

Colonel Psev, a mysterious and unseen foreign spy with a toy fixation, arrives in London to infiltrate a defence conference. His four aides bully Brodny, the ambassador, until he comes up with a cunning ruse: Gordon Webster, rakish male model, is Steed's double.

Christmas. Steed is having bad, seemingly prophetic, dreams, involving festive themes and a dead agent. Can he find solace at a fancy-dress party in the country home of a Dickens enthusiast?

The lack of martens in a pleasant stretch of English countryside alerts Steed to the possible release of a fertiliser that has failed, reducing a landscape to a wasteland. But why is the local farming community so aggressive?

A brilliant scientist reappears at the house of his wife. Has he escaped from notorious Manchurian prison camp Ni-San? And why have so many missing people stayed at the Chessman Hotel? Steed and Emma book in.

Steed returns from holiday to find that a quite different Mrs. Peel is inhabiting his old friend's flat. With the aid of actress Georgie Price-Jones, he discovers that Art Incorporated and the Arkwright Knitting Circle are doing more together than just sharing needles.

An agent is shot on the thirteenth hole of the Craigleigh golf club, so Steed and Emma join the club. Steed puts his limited skills to use in a murderous tournament, but Emma helps him get a hole in one.

When an agent at the Ministry of Top-Secret Information is murdered, Steed and Tara have little difficulty in locating the man responsible. But when a handwriting test indicates that he is Boris Kartovski, someone Steed thought he had killed in Berlin 5 years before, our heroes find themselves drawn into the dangerous experiments of Dr. Constantine.
