Love and Hatred by Marie Belloc Lowndes

There are certain winter days when bed and bath seem to be the only two tolerable places in the world.

Katty Winslow, on waking up the next morning, that is, on Saturday, the seventh of January, knew at once, though she was snuggled down deep in her warm bed, that it was very much colder than it had been the evening before. She shivered a little, telling herself that perhaps she was not in as good condition as usual, for she had only just come back from spending Christmas and the New Year away.
