Reading Norah Labiner’s latest novel, Let the Dark Flower Blossom, reminded me of watching “Tinker Tailor Soldier Spy”: the multiple-episode BBC series released in 1979 (not the greatly condensed remake that hit theaters in 2011). A certain amount of disorientation is built into the experience: mysteries are wrapped in mysteries, and the paths to resolutions (to the extent resolutions exist) are rarely clear or trustworthy. Yet with both the TV series and the novel I was driven forward by the mysteries’ peculiar unravelings and, in the latter case, by the haunting beauty of Labiner’s writing.
