I was 14 years old in 1968, so just on the periphery of the "hippie movement". Although I do recall there being the element as described in The Rose Arbor (and perhaps they were more prevalent & long-lasting in Great Britain than in the US), I was somewhat uncomfortable with the narrow description & decidedly negative interpretation of that aspect of cultural history. The '60s were such a time of upheaval of societal norms with protest movements ranging from civil rights to anti-Vietnam war, the sexual "revolution", equal rights being proposed for women, and the proliferation of illicit drugs (at least where I lived in the US). I agree with mceacd's & MariontheLibrarian's comments above. There were many things happening at the time. The lumping of all counter culture advocates into this narrow, pretty extreme & very one-dimensional grouping & labeling them as "hippies", just didn't feel right to me. That being said, I could see how the characters in the book (Liz with her isolated upbringing & academic success and the other two with their very conservative, rule following & enforcing careers) would definitely have this conversation. Unbeknownst to the reader at the time, this conversation also was a plot assist for further into the story, which shows just how skillful a writer Rhys Bowen is. Still . . . history has many examples of groups who believed in & tried to build utopian societies who did not fall into the abysmal portrayal of the ones in this story.
