McEwan still has the power to surprise; to anticipate what his reader will be thinking and make hay of it.
All through this I wondered at the reason behind his writing in Serena’s first person and what sort of personal whimsy or predilection might be behind it. That he (she ) wonders if there might be a hint of gender issues in Tom Haley’s writing (and persona) led me to wonder (not for the first time) just the same about McEwan. Then here she comes in the final epistle to toy again with the theme, but now from Tom’s point of view,and at the same time, reveal the he (McEwan) has, all the time, been writing in Tom’s persona as he (Tom) attempts to write from Serena’s point of view! Almost more fun in the diagram than in the execution, still, McEwan’s Serena is mostly credible ( and where not, one can grant that it is just Tom’s failure, not McEwan’s). Interesting and just kinky enough to add spice.
No masterpiece, but a fun spy story with more human insight and value then any but the best of its genre.
