There is something fiercely interesting in deep despair, in the wringing of hands at the irreparable, in howling upon the brink of suicide. Then one truly learns human nature; one may blend one’s personality with life’s delicious fever. I am not raving; I speak quite naturally. Not every woman can seek consolation in religious ecstasy.A dead body is found in an empty house in one of the grandest areas of Oslo.
