Lawrence's first book, "Babylon's Ark", written with Graham Spence, was in galley form at the time, and provided useful context and guidance. Each morning Terry would sit with Lawrence to gain a more complete understanding of the events which occurred before, during, and after Lawrence's effort to save the animals at the zoo. Each afternoon Terry would write pages of the script and submit for Lawrence's review. This process was greatly aided by Lawrence's wife Francoise Malby and his son Dylan.
