He killed his wife and then pleaded for her safe return. Mike Gifford-Hull murdered mother-of-two Kirsi at the family home in Winchester. He then appeared on Meridian in a tearful appeal for information. Now, a body language expert has studied Mike Gifford-Hull's reaction for a television documentary. He says Gifford-Hull's behaviour, and in particular the way he was blinking, proves he was guilty. Tom Savvides takes up the story.

The full interview with Body Language Analyst Cliff Lansley can be seen on 'Faking It: Tears of a Crime', Investigation Discovery, 10pm Friday night.
