OK, does George Clarke instill the willies in anyone else? It's the eyes, and the intense whispering... and the unbridled joy when he's stripping a house. Tonight he's helping sets his sights on a battered and bruised family house in Brixton, reconfiguring rooms and maximising wasted space to transform it into a dream home. Meanwhile, fellow architect Angela (I'm Irish, wouldn't you know) Brady travels to Italy to unlock the secrets of Venetian style. This is followed by something entirely different at 9.00pm, Saving Africa's Witch Children. A 29-year-old Englishman has devoted his life to helping tormented youngsters in the poorest parts of Nigeria, where evangelical religious fervour is combined with a belief in sorcery and black magic. Here, many thousands of children are being blamed for catastrophes, death and famine: and branded witches. Denounced as Satan made flesh by powerful pastors and prophetesses, these children are abandoned, tortured, starved and murdered - all in the name of Jesus Christ.
