After graduating from their respective colleges, Caldwell began working with Thomason on the novel The Rule of Four. After writing together for a summer, the two continued to collaborate online for the next five years. The plot centers on four Princeton seniors attempting to solve a mystery related to the Hypnerotomachia Poliphili, an Italian work from the early Renaissance.

It took Caldwell ten years to complete his second work, The Fifth Gospel, which was published by Simon and Schuster in 2015.
