Marlene Dumas at Tate Modern

Just a week left to rush to the South bank to see this one. Dark, disturbing, a challenge to your sense of what makes a portrait, this huge retrospective, the first in Europe, is not to be missed.

For the portraits of the famous, it is worth the price of admission alone. Go, go, go. Stop reading this and go.

Dumas crafts from photographs not life and transforms her subjects into something quite other.

Favourite things are the children - more scary than innocent, the Magdelena series, which includes the haunting portrait of Naomi Campbell, and her twists on conflict in the Middle East.

The one I wanted to slip into my bag and take home was Girl with a Skull - I could weave stories from it for days. If you want to see Amy Winehouse in blue, this is where you'll find her. Full of images and not a burden at all. Breathtaking. Hurry.
