Who is Jane Somers from Prisons We Choose to Live Inside and what is their importance?

Lessing uses the pseudonym, Jane Somers, while undertaking an experiment. In the experiments, she offers two books by Somers to publishers. Ironically, the books are rejected by her own publishers in Britain, but they are accepted by foreign publishers. When she reveals the trick, the British condemn the books and everyone else praises them, just as Lessing predicts.
