Ruth is forty-six, of medium stature, with brown hair and blue eyes. She is a biologist specialising in wolf behaviour. A week ago, she received a scholarship from a private institution to write a book about these animals. Ruth maintains that by means of howling, communication can be established between our species and theirs. Wolves can pass on lessons of cooperation, solidarity and affection. The Secret of the Wolf is the title she intends to give the book. This is why she is living alone in a cabin in the woods. Having gone through two divorces, and having no children or close family, wolves became her only passion; she even confessed to a colleague that she prefers their company to that of humans – “wolves don’t lie,” she said.
