There’s more invention crammed into the opening ten minutes of this ensemble piece than in an entire hour of some of the other shows on the fringe.

The simple set - two six foot boxes that can be moved together to signify doors or have a hole cut in them to be a ‘mirror’ and a gauze covered screen - is moved in a dazzlingly well-choreographed opening as the main protagonists are introduced without speaking.

Projections on to the gauze become at various times a tube train, an office and steps in a block of flats. Black clad figures manipulate the scenery and props giving them a life of their own and giving the play a filmic feel.

At the heart of the play is a tragic tale based on the real-life incident of the murder of Christophe Duclos, pushed in front of a train at Mile End tube station by mentally ill drug addict Stephen Soans-Wade.

The cast - who have devised and co-written the piece - introduce us to the people behind the headlines. The Christophe character is trying and seemingly succeeding to hold together a troubled relationship while the Stephen character is tormented by his own paranoia. In both cases the stagnation of the relationship and the feeling of a weakening grip on reality are well communicated by the play.
