Sight for Sara

It seemed like a perfectly normal birth: Mary and Gordon [text removed] never suspected anything was wrong with their first baby, Sara. The frequent rolling of her eyes was put down to wind; so it was three and a half months before they learned that Sara was blind, with cataracts in both eyes. Q.E.D.'s cameras followed the Bryces for four tense months as doctors and family struggled to rescue Sara from her world of darkness.

Robots: Taking the Biscuit

Understanding Rape

Rape is one of the world's most serious and fast-growing crimes. A recent London survey found that one in six women had been raped at least once. In America it's one in four: that's one rape every 17 minutes. Tonight's Q.E.D. presents film of an experiment carried out at an American psychiatric hospital near Seattle. Four women victims were brought face to face with four convicted rapists. Psychiatrists at the Western State Hospital believe that rape is learned behaviour, which can be changed. They saw this face-to-face confrontation as one possible way of doing this. Q.E.D. took the film to Grendon Psychiatric Prison in Buckinghamshire to find out whether such an experiment could be of any value here ...

Hugh Bromiley , a master firewalker and British martial artist, claims anyone can learn to walk on fire. Q.E.D, accompanied by a team of prominent scientists, observed the mass firewalk. Could the whole dramatic event simply be a dangerous delusion? Or does everybody possess untapped powers of mind over matter

The Eleven-Minute Mile

Some doctors thought he might never even walk. Now he runs a mile every day and over the past year, 7-year-old Doran Scotson has been aiming for a time of 11 minutes. Not beyond many boys of his age: but Doran is different. Severe jaundice at birth damaged his brain leaving him horribly handicapped.

His sister, Tracey, is not affected, but she could be a carrier - in danger of passing the disease on to any male babies she may have.

In this second report, Q.E.D.'s cameras continue eavesdropping on the detective team led by Dr Ian Stead as it pursues its enquiries into the death. Why was Lindow Man killed?
