“Dodgy prawns,” insists the narrator in Replay, the affecting solo show written and performed by Nicola Wren, were the cause of her violent physical reaction upon hearing of a man’s suicide. It wasn’t pregnancy or anything else. The narrator, a woman police officer (identified only as W in the program), assures the audience that she is made of sterner stuff than to be shaken by the emotional impact of meeting the wife and daughter of the man, who took his life earlier that day. Dodgy prawns: This is her story, and she is sticking with it. As W describes in painful detail the personal turmoil surrounding her visit to the London home, one begins to suspect the prawns may be receiving a bum rap.
