The River of Love — Barbara Cartland

When they had gone back to the yacht, the Duke of Darleston took her down to his private cabin to put his arms round her.

Then he was kissing her until Irisa felt that they had found a special Heaven in which there was nobody else, not even the gods but only themselves.
