I rate William Boyd as one of my favourite authors, so when I say that “Sweet Caress” [affiliate link] isn’t his best work you have to calibrate it appropriately.
As a structure, it’s almost identical to “Any Human Heart” [affiliate link]. It’s a journal or memoir of an interesting character, covering pretty much their entire life. In this one, Amory Clay is born early in the twentieth century and lives a full life as a photographer in Europe, North America and Asia. The timing allows her to see the World Wars, the rise of fascism, the Vietnam war and much more besides. It covers her successes and failures, and the consequences of them both.
