The head of the sledgehammer was cold, icy cold, and it touched his forehead as gently as a kiss. 'Pock! There,' said Czernobog. 'Is done.' There was a smile on his face that Shadow had never seen before, an easy, comfortable smile, like sunshine on a summer's day.

'Yes. For today,' said the old man. 'By tomorrow, it will all be Bielebog. But today, is still Czernobog.' 'Then why? Why didn't you kill me when you could?'
The old man took out an unfiltered cigarette from a pack in his pocket. He took a large box of matches from the mantelpiece and lit the cigarette with a match. He seemed deep in thought. 'Because,' said the old man, after some time, 'there is blood. But there is also gratitude. And it has been a long, long winter.
