The Charlemagne Pursuit

In his fourth adventure, Copenhagen bookseller (and former U.S. government agent) Cotton Malone seeks the truth about his father, the commander of an experimental submarine that vanished in 1971. His quest makes him a target of the murderously ambitious Admiral Ramsey, an architect of the coverup, as well as an unwilling competitor and ally to twin German heiresses also looking for information about the fate of the submarine and its mission to Antarctica to search for an ancient civilization. Scott Brick's reading is perfectly acceptable, if not exceptional, and he keeps the many action sequences well paced. A reasonable attempt is made to differentiate between the genders of the characters, but Brick's accents (particularly the German) skirt the thin line between believable and comedic. His reading doesn't detract from the text of this solidly exciting, over-the-top thriller, but it doesn't enhance it, either. A Ballantine hardcover (Reviews, Sept. 29). (Dec.)
