I see that I had started this once before and gave up. I'm glad I returned to it, but I confess to ambivalent feelings now that I've made it to the end.
Martin Clay is a British philosopher who can never seem to finish his projects, married to a younger wife, Kate. Together, they and new baby Tilda go to the dilapidated country house they visit in the summer, ostensibly so that Martin can finish a book about nominalism in the Netherlands that you can tell he barely cares about.
To their surprise, they encounter a local landowner on their arrival, Tony Churt, a bumptious, arrogant owner of a great pile, surrounded by his manic dogs, his young sensual wife Laura and his many failed schemes to make money to save his estate.
The crux of the book is what happens on the Clays' first visit to the Churts, where Tony wants Martin's opinion on the value of a huge painting of the abduction of Helen. In the process, Martin sees another painting on a wooden board that immediately spellbinds him, and which we find out he suspects is by Peter Breugel the Elder.
From then on, Headlong is either a farce masquerading as an art history essay, or the obverse. When Frayn gets rolling with the farce, as he does in the frenetic climax of the book, it can be bracing and riveting. But when he takes you inside Martin's scholarly pursuit of trying to prove the painting is a Breugel and putting it in the context of the Spanish persecution of the Netherlands in the mid-1500s, you have to have a very high tolerance for geekiness (which I think I do, which is probably what got me through those passages).
In the end, though, my real problem with the book was that once again, I had encountered a main character whom the author had made you empathize with and even like, until you took two mental steps back and realized you never understood his sudden impulse of greed in the first place or exactly how much he loved anyone but himself.
Why three stars after all this doubt? Because Frayn is a wonderful writer, and sometimes, I just let that tip me one star up the ladder.
