The last in a series of four historical detective stories. Written and presented by Michael Wood
The Norman Conquest is the most famous event in British history. It is also the most controversial. What actually happened in 1066 and why?
MICHAEL WOOD concludes his personal history of the so-called Dark Ages by going in search of William the Conqueror in Normandy and England.
In Normandy, William's dukedom, the sense of history is ever present. Where the Normans set off in 1066, the allies landed in 1944. Caen, citadel of William the Conqueror; Bayeux, where the great tapestry reveals Harold's fateful advance to the English throne. St Germain de Montgomery, ancestral home of the Field-Marshal who returned in 1944. In England, the Battle of Hastings and the Conquest represent the climax to this film and the series. As the Normans fastened their hold on England by building motte and bailey castles everywhere, the Anglo-Saxon era came to an end. In the Public Records Office in London is the Domesday Book; here Michael Wood reveals his own sorrow at the passing of the chief makers of England.

This week: Some of the Nicest People I Know Have Had VD
It is no respecter of persons: monarchs have had it, statesmen have died of it. And although it's been called ' the wages of sin', innocence doesn't guarantee protection - the sexually faithful can get it from a partner who strays even once.
VD or, as it's now called, sexually transmitted disease, was on the retreat 30 years ago. It looked then as though penicillin and other drugs would banish it from our lives. But today STD is spreading again and with alarming speed, especially among the young. This year something like half-a-million cases will pass through British clinics. Doctors will treat people from every social class, not just for syphilis, gonorrhoea and NSU (the infamous three), but for more than 20 other sexually transmitted diseases, including genital herpes, the incurable virus that is already an epidemic in America.
Man Alive visits the clinics where the war against the sexual diseases is being fought and Michael Dean talks to the doctors and to some of the casualties.
