Murder on Pratas Reef By Rick Ainsworth (257 pages) Reviewer:  Terry Miller Overall Rating: Four Stars--Highly Recommended. An excellent book. Murder on Pratas Reef is a Historical Novel set against the backdrop of the actual events associated with the grounding of USS Frank Knox (DDR-742) and her eventual rescue more than a month later. In Ainsworth's book, when the Knox hits the reef, a murder is taking place aboard the ill-fated destroyer. Continuing characters from his previous book, Thunder and Storm: The Haverfield Incident, come to play important roles in solving this case while assisting in the 37-day effort to free the Knox from the reef's grip. Ainsworth also illuminates the little-discussed racial tensions of the mid-60s, bringing the problem into sharp focus. The interaction between destroyer and destroyer tender show off the fact that Murder on Pratas Reef is informative, as a historic novel should be but is also highly entertaining. I definitely recommend this book to all who enjoy military fiction.
