A Zimbabwean writer who was arrested during anti-government protests is among six finalists announced yesterday on a diverse list of contenders for the prestigious Booker Prize for fiction. The Associated Press reports that Tsitsi Dangarembga was nominated for the $64 000 award for ”This Mournable Body,” which links the breakdown of its central character and turmoil in post-colonial Zimbabwe. Dangarembga, one of Zimbabwe’s most garlanded authors, was arrested in July and spent a night in detention for standing by a road in the capital of Harare and holding up a placard that said ”We Want Better. Reform Our Institutions.”
