The Swan Thieves combines two stories in two different eras, much like the wonderfully fantastic Possession. In the present day, artist Robert Oliver attempts to stab the (fictional) painting Leda at the National Gallery and after he's subdued, he's committed to an institution - where his psychiatrist, Andrew Marlow, spends the book trying to puzzle out his motives. About a hundred years before that, fledgling artist Beatrice de Clerval begins a love affair with her husband's older uncle. As the story moves on, we find out that Robert is obsessed with the mysterious Beatrice, dead long before his birth, and Marlow himself becomes obsessed with figuring out why.
I think the main problem with The Swan Thieves was that none of the modern-day characters were terribly likeable. Robert is portrayed as both a narcissist and a genius, and I think that we're supposed to root for his recovery so he can go on being a genius, but he was so self-absorbed - and treated all his loved ones like crap - that I really didn't care what happened to him. I found everyone else to be kind of pathetic - Robert's loves, Kate and Mary, were so damaged by him and Marlow was so overeager that it seemed perhaps he needed a little professional help himself. I found Beatrice's conundrum and narration to be a lot more interesting but unfortunately, she just wasn't in the book as much.
I also didn't care much for the ending, mostly because Robert's story wasn't actually resolved. I feel like Kostova focused so much on Beatrice's ending - which was well-written and poignant - that she forgot that Robert's illness had to actually be resolved, instead of just dismissed. Marlow's solving of the mystery shouldn't make the mute Robert better, but that's essentially what happens - Marlow figures out why he was trying to stab a painting and poof, Robert's better. But the problem is, Marlow never actually addresses what sort of disturbance has made Robert resort to such an action - we may all think the fictional Gilbert Thomas is a cheat but I daresay most of us wouldn't try to stab a portrait of him, if given the chance. And this is the mania in Robert that's never solved...and yet somehow, he's fixed. Ah, the wonders of fiction.
Well, I'm on to the next book, the lighthearted Rude Awakenings of a Jane Austen Addict.
