'Field Slave Number 139' was written and produced by Ava Ming, and commissioned by The Drum in Birmingham as part of their Routes to Freedom programme. The play focuses on a love story between a dark-skinned field slave and mulatto house slave on a plantation in America's Deep South. 'Field Slave Number 139' is written mostly in monologues with occasional interaction between the actors: all three were on stage for the duration of the piece. The 2007 production featured two performance poets and a local actor.
