In 1864, the H. L. Hunley became the first submarine to sink an enemy ship. It then vanished. For 131 years, the Hunley's fate remained a mystery. Walker has crafted a seamless account of historical and scientific sleuthing to reveal the secrets of the Hunley and her crew, all the while demonstrating the interdisciplinary nature of the problem-solving process in our modern world. Walker combines the drama of a wartime shipwreck with compelling scientific writing to create a work of true distinction.
