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....

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?

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 a scientist is found embedded in a wall, Steed and Emma pursue a man in make-up and wellies, whose appearance is terribly shocking.

Problems of a secret leakage from Cypher HQ and the disappearance of agent Jarret are first handed to rival Department MII2, and then to Mother's group. But why does everybody at Cypher HQ claim never to have seen Jarret and state that the only thing worthy of note that happened yesterday was that it rained?

Somebody is out to get super-computer George/XR40. He is shot, given false data, attacked with acid, and nearly gets his power supply cut. But until George works properly the name and nature of the culprits cannot be established.

Remak is a killer, one the department are desperate to find. But a succession of agents on the trail of Remak are turning up dead, wrapped in polythene. And with Tara on holiday, Steed must go into this case with a new partner.

Tara's uncle is being held against his will in a country hotel. So Tara books in, and finds herself equally discouraged from leaving. Could the place also be home to the agent that Mother is missing?
