The Good Shepherd, by C.S. Forester, is the basis for the Tom Hanks film Greyhound. On one level, the novel tells the history-inspired story of a convoy of supply ships surviving the hazards of a trans-Atlantic sea voyage in the middle of World War II. On another level, it is the story of how the convoy’s leader, Commander George Krause, achieves a long-sought sense of self-worth over the course of his mission. As it chronicles the challenges, failures, and successes of Krause and the ships under his command, the novel explores themes related to the nature of duty, the power of Christian faith, and the need for releasing the disappointments of the past.
