Now, in a state of calm reflection, Olav listened to the only voice that spoke to him in a language he understood. Here, in this foreign land, all other voices shouted at him as if there were a wall between them and him. Yet the voice of the church was the same one he had listened to as a child and a youth and a grown man. He himself had changed in terms of goals and thought and speech as he moved through the stages of life, but the church had changed neither voice nor meaning. It spoke to him in the holy mass just as it had spoken to him as a little boy, when he understood very few of the words yet still understood much by observing--the way a child understands his mother by watching her expressions and gestures before he understands the spoken words. And Olav knew that if he traveled to the farthermost regions where Christian men lived, their language and customs and appearance might seem strange and incomprehensible to him. But wherever he happened upon a church and went inside, he would be embraced by the same voice that had spoken to him when he was a child.
When we last left Olav Audunsson, his wife Ingunn had just died after a long illness. Ingunn's death resolves what might have seemed like the central tension of Undset's tetralogy, the love between the man and woman that thrived in spite of all the machinations of their families to drive them apart. I admit I was surprised, but I had to remind myself that, as one learns in Kristin Lavransdatter, Undset is no believer in the primacy of romantic love when there is a higher love, and a higher law. But Ingunn's death leaves Olav in a strange place, having taken in Ingunn's love-child Eirik and raised him as his own, while his own bastard, a son named Bjorn with a woman named Torhild, is at a neighboring estate. It's Eirik that will inherit the manor Hestviken, despite Olav's dislike of him (and he is quite annoying, apart from being the son of another man), while Bjorn exists for Olav only as a reminder of lost possibilities.
The first part of Crossroads is taken up by a trip to London, where Olav does some merchant business. Olav, lonely and adrift, nearly enters into an adulterous relationship with the wife of a blind man, but runs away at the last minute, repelled by her strangeness and foreignness. The blind man's wife speaks in a language Olav can't understand, but during his trip he rekindles his love for the church, which, as described in the passage above, speaks in a universal language that can be understood no matter where Olav is. Olav decides, with only some misgivings, that he will never remarry, and devote the remainder of his life to the memory of Ingunn and to the church.
The novel's subtitle suggests that it captures Olav at a "crossroads," and the novel feels like a crossroads, too, a necessary transition between points of stronger dramatic tension. The conflict that's established between Olav and Eirik only festers. Though the two find a way to become somewhat closer, Eirik's anxiety that somehow his inheritance will be stolen from him--deep down, perhaps, he understands something that he cannot articulate about why his father is so alienated from him--make him especially anxious and unreliable. Ultimately, Eirik flees from the conflict, entering into a knight's service, and the last time we see him, he has grown at last into a man. Olav is left with his manor and his daughters, but more or less alone.
The novel ends with something I'd never seen from Undset before: an honest-to-god battle. When Olav hears that Norway has been invaded by a Swedish duke, he and his fellow knights are called into battle to repel the party of the invaders. In the melee, Olav is badly wounded and left facially disfigured. (Perhaps sealing the deal on that promise to never remarry.) This, it felt to me, was the point to which Crossroads has been leading our hero: ravaged, abandoned, and yet with a renewed sense of his own obligations to God and country, which perhaps will steel him in whatever crisis of inheritance and fatherhood is coming in the series' final installment--coming, for this reader, next December.
