'Sea Wall', first performed at London's Bush Theatre in 2008, is a delicate monologue, completely devastating and beautifully powerful. Alex's story, spoken directly to the audience, begins full of clear light and smiles, as he speaks about his wife, visiting her father in the South of France, having a daughter, photography, and the bottom of the sea. His tone is natural, happy and engaging, with flickers of questions about belief and religion glimpsed under the surface. But his contentment falls away into deep and heart-breaking grief, crumbling to pieces with a vividness that is incredibly moving.
