This is the 14th book in the Neptune King series. In Neptune's Nightmare, he believes his worst fears are realized when he sees Rachel with another man. He becomes even more disenchanted when he finds that he is missing a large sum of money and even witnesses 'Rachel' withdrawing cash from the bank, after she had told him she was going straight home. Is this the end for the pair of lovebirds? All is not what it seems, fortunately, but the solution almost costs Rachel her life. In The Case of the Phobic victims, Neptune and Shark go undercover at a phobia clinic, Neptune as a Zoophobic patient, and Shark as an orderly. Someone is terrorizing the patients and turning their phobias against them. Finally in The Case of the Unhappy Unicorn, they go to Exeter to discover why a unicorn has suddenly appeared on Lord Bainbridge's nature reserve. Is it unhappy because he plans to sell ten acres to a furniture factory, or has it something to do with the radical protestors trying to stop the sale. Does a unicorn really exist, or is it a fake? Neptune hopes to prove this one way or the other, and enlists Suzy Johnson's help.
