As a policeman, Jack probably didn’t often have the luxury of heading to bed at nine with a glass of hot milk and a good book. When he did, though, Zane Grey seemed to be a fitting choice with themes like adventures in the wilderness, moral heroism, code of chivalry, etc. Although published in the United States as early as 1903, there’s no clear record when his books first became available in Australia, but according to Google AI they were extremely popular Down Under during the 1920s.
In contrast, DH Lawrence’s most famous book “Lady Chatterley’s Lover” was banned in Australia from 1928 until 1965. Of course, it didn’t stop Phryne from reading it in public, like on the Ballarat Train on her way to pick up the Hispano Suiza. Jack was not wrong about her choice of reading material, but it didn’t paint a full picture. Apart from DH Lawrence and “Erotica of the Far East” (as shown to Hugh in S1E6 Ruddy Gore), she was rather widely read. As described by Miss Kerry Greenwood in the book series, Phryne often borrowed books from the library to study the subject matter related to the cases she worked on. For example, in Book 4 Death at Victoria Dock, she read about Latvia, Lithuania, Russia, and the Revolution for hours to brush up on her knowledge of the historical background and current affairs. Also, whenever Jack quoted Shakespeare, she was able to get the reference without missing a beat. Brain and beauty, that’s our Phryne.
