Steed and Dr Keel return to action in these three recreations of classic lost episodes.

6.1 The Frighteners by Berkeley Mather, adapted by Rae Leaver

If you need someone scared off, you speak to the Deacon.

Steed and Keel are on the trail of an intimidation expert whose services have recently been acquired by a wealthy businessman. But as they head deeper and deeper into this seedy world, who do they really have to stop. And who do they have to save?

6.2 Death on the Slipway by Ian Potter, from a storyline by James Mitchell

When a fellow agent is killed, Steed is sent undercover at a government dockyard to find the killer. Can he sort the truth from the lies and track down the enemy infiltrator hunting for top secret plans before it's all too late?

6.3 Tunnel of Fear by John Dorney, from a storyline by John Kruse

Southend. A perfect spot for a family holiday - or for a traitor to hide.

Somewhere in the town lurks a spy ring that is smuggling out classified information. When his old mole is attacked, and with innocent lives at risk, Steed takes Keel to the seaside for a far from sunny time.
