While flattered by her father’s dedication, in her later years Zeta herself attributes her father’s interest in mazes to his time in the First World War, the battlefields of which he left for in the year she was born. Although she surmises the seed to be his learning of a destroyed church maze on the Arras Front, one can’t help wondering if his experience of the labyrinth-like trenches may have played a role too. Whatever the seed, he was clearly hooked and, according to Zeta, "within two and a half years of returning from France he had researched, written, printed and published this book". A remarkable feat considering its breadth of scope and depth of exploration — and that he was on somewhat unchartered territory, it being the first book dedicated to the subject.
