The First Century After Beatrice

A French entomologist, attending a symposium in Cairo, finds a cruious kind of bean being on a market stall. It is claimed the beans, derived from the scarab beetle, have magic powers; specifically the power to guarantee the brith of a male infant - and when the entomologist does some research in to the matter, discovering the incidence of female birth has become increasingly rare, he is left in no doubt that the world has entered intoa critical phase of its history.
