It was one of those March days when the sun shines hot and the wind blows cold: when it is summer in the light, and winter in the shade.

– Charles Dickens

Great Expectations, Chapter 54. The chapter’s opening sentence captures the contradictory, paradoxical and uncertain nature of March weather. The words by narrator Pip also reflects the anxiety felt by him, Herbert and Startop as they set about taking Magwitch down the Thames to get him safely out of London.
