Red Sky at Morning is a 1927 novel by the British writer Margaret Kennedy, her third.

Sylvia Lynd reviewed it saying "Few novels have so exquisite a forerunner as The Constant Nymph with which to compete.

Compared with that, Red Sky at Morning, it must be admitted, is far less moving, less inevitable in the progress of its events, and less well stocked with fascinating characters.

At the turn of the century, twins Emily and William Crowne grow up in privileged comfort at the London home of their poet father.

However, when their mother dies and her father flees the country after being caught up in a notorious murder case they are sent to live with their aunt and cousins in the countryside.
