The problem I have with the way it's written is the frequent changes in style - the description above of Windsor as a tomb, quite literary and flowery, against the very choppy, short sections.
It's a deliberate choice. Short choppy sentences are for propulsion, and the longer sentences and passages are for moments of contemplation or description.
You can't exactly write.
Balmoral. Big castle in Scotland. Bowed to Queen Victoria.
Whereas you can say:
Ski instructor? Pa tensed. Out of the question. Ok. Um, safari guide? No, darling boy, that won't do.
Harry invoking Shakespeare, yup, totes believable.
Harry does not invoke Hamlet, the ghost writer does, as a literary device.
That said, Harry does actually talk about Shakespeare. There is a great passage about Charles's love for the Bard, including the speech he gave on Shakespeare. Harry also has a funny story about performing in a Shakespeare play before he could leave Eton and Charles laughing at the wrong bits. Harry also says specifically that he tried to read Hamlet, but found the subject matter (Prince obsessed with dead parent, Prince sees ghost of dead parent, Prince dealing with usurper of dead parent) too close to his own life so didn't finish it.
That's the Hamlet theme JR picks up on and threads through the memoir. Pretty obvious, I would have thought, as the parallels are so striking.
