Query: == Groucho is Back! ==

Ron Goulart has managed to capture the spirit of Groucho Marx in wit and dialogue. Although that alone gives this book a life of its own, the plot and character development is masterfully delivered and a joy to read. I can imagine no other than Groucho himself uttering every line. A must for Marx fans and a good mystery for fans of the genre.
