From the cover 'Nicola and Lawrie spend an Easter holiday by the sea with their mother, Ginty (their next eldest sister) and Peter (the brother at Dartmouth). Things start to happen when Nicola and Peter, out for an early morning walk, meet an instructor from Dartmouth who cuts Peter dead - and the excitement mounts to a tremendous, but plausible, climax, with the Marlows living up to the best naval traditions.'
