It all began as a joke. But when a friend of Tricia’s was diagnosed with leukaemia it turned into a nude photo shoot, a WI calendar, a press release, a national news story, a film, two tours of America, a book, another calendar…and now a talk at Purley Lit. In five years the idea has raised nearly a million pounds for leukaemia research. Tricia tells us the whole compulsive story (she’s the one who looks like Helen Mirren).
