This quick little addition to the series, far more subdued than the previous "phase," is paradoxically a better introduction for newcomers to Adams's often imitated brand of satire. Arthur Dent, the series' protagonist and straight man, returns home to a destroyed and rebuilt Earth (identical to the one he left but for the lack of dolphins) and promptly falls in love. The object of his clumsy affections is Fenchurch, a young woman who had been on the verge of comprehending the secret to eternal contentment when Earth was destroyed. In order to recover her lost revelation, Fenchurch and Arthur (and some of his old hitchhiking friends) seek out God's final message to his creation, written in fire on the top of a mountain in a distant part of the galaxy. The story is straightforward by series standards and depends little on previous (and, as yet, unreleased) episodes of the radio program; the humor is decidedly low-key and the running time surprisingly short. All of this allows easy access for first timers, but won't leave a big impression on fans, especially after the promise of the perfectly zany Tertiary Phase

American readers may not be aware that Adams's sci-fi parody classic started out as a BBC radio production. This audio, which contains a portion of that radio serial, will have listeners glued to their CD players. Never a dull moment passes in this uproarious dramatization, as Arthur Dent—a refugee from Earth, which was destroyed to make way for a galactic freeway—escapes from prehistory, and self-imposed insanity, on a time-traveling sofa along with his alien friend, Ford Prefect, who is a reporter for the eponymous guide. The pair find themselves reunited with old friends (such as Zaphod Beeblebrox, the two-headed president of the galaxy) and swept up in an attempt to stop the explosively xenophobic denizens of the planet Cricket from wreaking havoc on all of existence by behaving remarkably like players of the British sport of the same name. Each CD contains two episodes full of hilariously appropriate sound effects, dramatic music and witty fake advertising, and every performer brings his or her character to life with aplomb, including Adams, who makes his appearance in one scene as Agrajag, an entity that is killed and reincarnated innumerable times. Fully embodying the zany otherworldliness of the series, this audio production is a treat for anyone familiar with the Hitchhiker's books (the first of which will debut as a major motion picture from Touchstone in May).

From Kirkus

It's been more than a quarter century since Douglas Adams's original radio series was first broadcast. In the able hands of director Dirk Maggs, Adams's third novel about Arthur Dent, Life, the Universe, and Everything, has been adapted as a radio drama and brought to life with most of the original cast from the first two series. Simon Jones reprises his role as the chronically disgruntled Arthur Dent, an earthman cast about in time and space when the earth is destroyed. Geoffrey McGivern is back as the easy-going Ford Prefect, and Mark Wing-Davey is the two-headed hipster, Zaphod Beeblebrox. Fans will be pleased by the return of Susan Sheridan as Trillian, who was conspicuously absent from the second series. Even Douglas Adams, who passed away in 2001, makes an appearance as the continuously reincarnated Agrajag. Through the wonders of digital sound editing, dialogue from an audiobook version of LIFE, THE UNIVERSE, AND EVERYTHING read by Adams was seamlessly spliced in, along with Simon Jones reading Arthur Dent's parts. Roger Gregg of Crazy Dog Audio Theatre plays Eddie the Shipboard Computer, giving a cheerful counterpoint to Stephen Moore's hilariously depressing Marvin the Paranoid Android. All in all, a delightfully manic treat. S.E.S. Winner of AudioFile Earphones Award, 2006 Audie Award Winner (c) AudioFile 2005, Portland, Maine
