Zimmer's wife, Lil, says their love is dead. He says it's just tired. Divorcing, he feels as if his whole love life is passing before him - and then part of it really is, in the still-sexy person of old flame Rhona Glinsky.

In artfully crafted interlocking flashbacks set against a vividly drawn scrim of New York City, Busch lets his hapless hero tell his story of the angst-driven complications of both licit and illicit love. It was Greenwich Village in the Sixties, and Zimmer was writing copy for a sleazy PR agency. Rhona was a voluptuous Nazi-hunting librarian who taught him introductory love and guilt and drove him into the arms of the tall blonde shiksa Lillian.

And now, twenty years later, the middle-aged Zimmer is proving that opposites still attract, by falling in love - again - with both of them. Invisible Mending is Frederick Busch's half-comic, half-serious mediation on Jewish identity and consciousness - an ambitious grapple with the New York/Jewish ethos.
