A sharp frost

A sharp frost last night, sharp enough that it looks as if a corner of it is not going to shift before the next one.

A corner which starts the day in the shade, and, at this time of year, by the time the sun has worked its way around to the other side of the house, it is too low to reach this last corner, which stays in the shade of the leylandii bushes to its left, that it to say, to its south.
