in Adventure, which was partly based upon real events. The story revolves around a regiment of Sikhs fighting on the Western Front for the British Empire who are then captured by the Germans; transferred to a Turkish prisoner of war camp, they attempt to escape and return overland to India. Casells published a British edition in June 1918, although for American publication in book form it was renamed Hira Singh. Talbot devoted the latter to his friend Elmer Davis, and gifted a copy to the British monarch George V, who was Commander-in-Chief of the 14th Ferozepore Sikhs. The book received largely positive reviews in the U.S., although was criticised in the Times Literary Supplement.

He also became vice president of the Society's magazine, New Earth News. Spending time at the
