The Marquis of Kexley is just falling asleep beside the beautiful Isobel Heywood, when in a soft voice she suggests that they should be married. Only by pretending to be asleep does he escape answering her and then he realises that because she is a widow, she is extremely dangerous in that she is free for him to marry her. In his other affaires-de-coeur, the women were already married, so he was safe, and he avoided debutantes with ambitious mothers like the plague. Because Isobel is so possessive he thinks it best to leave London at once. So with the assistance of the Prince of Wales he leaves on his yacht for Scotland to stay with the Earl of Darendell and fish on his salmon river. When the Marquis arrives in Scotland, he is surprised and upset to find that his hostess, the new wife of the Earl is someone who had approached him at a house party when he was only nineteen. While he is enjoying the fishing, he becomes worried and puzzled about Celina, the Earl's daughter, who is frightened of him and avoids him on every possible occasion. He only discovers the reason when one night he finds the beautiful Celina in his bed! How the Marquis avoids the dastardly trap set for him, how he escapes with Celina on his yacht to the Orkney Islands and how they are then faced with an even more dangerous situation is all told in this thrilling romance by BARBARA CARTLAND.
