Why have all the fish vanished from the Scottish coastline? Does it have anything to do with a dead frogman, found stretched as if on a rack? Steed and Emma think so, which is why they're guests of Ian, the 35th Laird of Clan De'ath, and in danger of being caught by the gillies.

A government official, dresssed as one of the Horse-guards, helps in a raid on secret files and is wounded. Recovering, he remembers nothing. Is his crime anything to do with his membership of Ransack, a club for those with high IQs? Emma can join, but Steed may have to cheat....

What could an outbreak of motiveless murders have to do with the activities of a marriage bureau called Togetherness Inc.? Well, think of Hitchcock's 'Strangers On A Train' and you'll be close. Steed and Emma seek their ideal partners....

Following a motor crash, Steed and Emma explore the seemingly deserted RAF Hamelin, where they were heading for a party to celebrate the base's closure. Is this surreal landscape all a dream, or is it something worse?

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.

Several military figures have been killed in dangerous games of daring. Emma and Steed follow the trail to a secret society of military men with very dangerous aims.

When a group of hoaxsters called the Hellfire Club mix murder with their mischief, Steed and Emma demonstrate a few tricks of their own.
