Indeed if one had just seen him at the end of the evening with the dusk and the mist of the fenlands close behind him he might have believed that in the dusk and the mist was an army that followed this gay worn confident man. Had the army been there Niv was sane.Had the world accepted that an army was there, still he was sane. But the lonely fancy that had not fact to feed on, nor the fancy of any other for fellowship, was for its loneliness mad.
