"Did you see Death go by with my little child?"
"Yes," said the blackthorn bush. "But I shall not tell you which way he went unless you warm me against your heart. I am freezing to death. I am stiff with ice."
She pressed the blackthorn bush against her heart to warm it, and the thorns stabbed so deep into her flesh that great drops of red blood flowed. So warm was the mother's heart that the blackthorn bush blossomed and put forth green leaves on that dark winter's night.
And it told her the way to go.
