Austin accountant Jack Grant goes to Los Angeles for a vacation and does a rich client a favor by looking in on her niece and the niece's new boyfriend. And the more he investigates the boyfriend the more trouble he encounters. Ultimately he walks into a trap and has to figure a way out.The novel is funny and well-paced. A steady diet of witty dialogue and a Beverly Hills setting make the book a good choice for an afternoon at the beach.
