Dirk Carter, formerly Lieutenant Carter, R.A.N, arrives in England from Australia where he and his girl-friend Rommi Hartmann hope to gain some experience in the Yacht Charter business prior to launching their own boat back home. They are invited to join Sir Hugh and Lady Helen Weatherham on their 65' ketch 'Sonnet' about to leave for the Mediterranean. Dirk has met his old sailing friend Duffy McGuire who also joins the crew.
Three days out from Chichester Harbour brilliant flashes in the Eastern sky paint the clouds red. Sketchy radio reports tell them that the Middle-East troubles have erupted into a full scale Nuclear War involving the Super-powers.
They return to Portsmouth and on the way make contact with H.M.Submarine 'Archer' which takes Sir Hugh and Lady Helen on ahead leaving Dirk to follow with the yacht.
Portsmouth, like the rest of Britain is a scene of total devastation, the result of large numbers of Nuclear warheads. Sir Hugh, now in complete authority orders the Submarine to Thorney Island, the site of Britain's biggest Emergency Supply Depot, which is housed in an underground complex. Sir Hugh's task is to set up the depot as a self-sufficient community.
Dirk having moored 'Sonnet' alongside the Submarine is asked by Sir Hugh to find his two sons who were attending a school in Surrey. This is the first of a number of adventures which includes an expedition to rescue the staff of another Supply Depot at Newhaven which is being attacked by survivors in an attempt to get at the supplies. These attacks are growing in number and ferocity each day as the survivors get weapons from derelict army bases, and culminate in a full scale attack on the Thorney Island Depot in which Sir Hugh is killed. His dying words ask Dirk to take Lady Helen and their son Barry to Australia. The third and final part of the novel is devoted to the voyage to Australia, in a world threatened by the huge clouds of fall-out travelling the globe and depositing their deadly 'Grey Rain' at will.
'Red Clouds, Grey Rain' is fast moving, has been extensively researched, and should, God forbid, the ultimate holocaust ever take place, the events described in this powerful novel will be all too familiar.
There are no more 'Rich or Poor,' no 'Military or Civilian,' there are no 'Friends', no 'Enemies.' There are merely the LIVING and the DEAD.
