Happy Harrow, a Kentucky hills jockey who moonlights as a sleuth, is married to Rick Harrow, an Eton-educated English racehorse trainer. Their training stables and home are in Epsom, England, a delightful and picturesque area. Their newest owner, Achilles Pinot, a tycoon of France's perfume industry gave them a completely pre-paid two week vacation in Morocco with their three small children. The gift had one condition, he asked them to chaperone his adored niece Pricilla who would be working as a temp school teacher in Agadir.

So the Harrows and Pricilla were all staying at the same hotel. Happy quickly discovered that chaperoning the young and provocative Priscilla was not easy. She was constantly picking up men off the street and invited them to come to her room either early in the evening or after midnight. The hotel recently developed a sinister reputation that appeared in the media after a teenage girl had been murdered there. The murder was attributed to a vampire because the girl had two holes on her throat that resembled pointed teeth marks.

After Happy and her family's first night in the hotel another teenage girl is murdered and has identical marks on her throat. With Agnes Murray, another hotel guest, Happy and Rick take Pricilla to another town, Essaouira; famous as a resort for surfers. There they meet Agnes' son, surfer Keith Murray, who has sharp-pointed canine teeth. After one look, Pricilla lusts to have sex with Keith. But, is he the Vampire? He often visits his mother at night in Agadir. More vampire-style deaths follow at the doomed hotel. The media has created frenzy that does not let up. To get to the truth, Happy enlists her friend Maheen Palazzo to be serve as her Dr. Watson-like aide; Sherlock Holmes-style to help solve the murders.

The saga travels back and forth to many cities in Morocco, Agadir, Essaouira, Marrakesh and Rabat.
