"Fresco"

Bianca returns from Northern Australia where she has lived with the Yolgnu tribe, studying their customs, their rock paintings and has even joined in their ceremonial dances (naked).  Her local church needs a mural for the hall and Bianca plans a fresco inspired by Aborigine art but she comes up against Unity who is a confirmed spinster and whose deceased father raised the money which will pay for the fresco ... friction ensues.  Royalties £25pp
