There are definite "themes" and they also vary over time. I'm reading some mystery / detective stuff from the mid-1910s through the late 1920s ... from US, Canada and Britain ... there's a strong change of direction in the 1930s and 1940s ... and good gravy ... ovels from the late 1960s and early 1970s from the US portray a radically different world view than their 1950s predecessors.
