“I didn't believe her, of course. The lie was transparent—it something that size, someone would have mentioned it during the door-to-door--and it went straight to my heart as no sonata ever could have; because I recognized it. That's my twin brother, his name's Peter, he's seven minutes older than me. . . . Children—it and Rosalind was little more—it don't tell pointless lies unless the reality is too much to bear.”

“This is not an easy thing to admit, but until that moment I had held out some craven speck of hope that this had all been a hideous misunderstanding. A boy who would say anything he thought you wanted to hear, a girl made vicious by trauma and grief and my rejection on top of it all; we could have misinterpreted in any one of a hundred ways. It was only in that moment, in the ease of that gratuitous lie, that I understood that Rosalind—the Rosalind I had known, the bruised, captivating, unpredictable girl with whom I had laughed in the Central and held hands on a bench—had never existed. Everything she had ever shown me had been constructed for effect, with the absorbed, calculating care that goes into an actor's costume. Underneath the myriad shimmering veils, this was something as simple and deadly as razor wire.”

“I think it was only in that moment I believed she was dead, this girl I had never seen alive. I'll never be free of her. I wear her face; as I get older it'll stay her changing mirror, the one glimpse of all the ages she never had. I lived her life, for a few strange bright weeks; her blood went into making me what I am, the same way it went to make the bluebells and the hawthorn tree. But when I had the chance to take that final step over the border, lie down with Daniel among the ivy leaves and the sound of water, let go of my own life with all its scars and all its wreckage and start new, I turned it down.”

“But give me more credit than that. Someone else may have dealt the hand, but I picked it up off the table, I played every card, and I had my reasons.”

“That house shimmered in my mind like some fairy fort that appeared for one day in a lifetime, tantalizing and charged, with those four cool figures for guardians and inside secrets too hazy to be named. My face was the one pass that would unbar the door. Whitethorn House was ready and waiting to whisk itself away to nothing, the instant I said no.”

“What I am telling you, before you begin my story, is this -- two things: I crave truth. And I lie. ”

“Frank told me once--and I don't know whether he's right or not, and I didn't tell Sam this either--that all the best undercovers have a dark thread woven into them, somewhere.”
