It would have been easy for Sabine to hate me — to see me as the man who swallowed his mother’s story, who stopped searching, who let her run pregnant and alone into six years of struggle while I attended openings.

By every reasonable measure some of the blame was mine, and she had every right to lay it there.

But she did not, and the reason she gave was the truest thing anyone said in the whole ordeal: that we had both been deceived by the same architect, from opposite sides of the same wall.

My mother had told me Sabine abandoned me.

My mother had told Sabine that I wanted nothing to do with her.
