Can Nicole Krauss tie together the many strands of Great House?

By this point, 2/3rds in, I'm not sure what to make of Nicole Krauss's promising but elusive novel "Great House." As noted in previous posts, she gets the novel off to a great start, posing the mystery of a desk that gets passed around among several writers and affects their lives in varying ways, and ultimately one of the owners of the desk "disappears" during the Pinochet regime in Chile - setting off a search for him, in a sense - a great beginning, but now I'm a long way through and instead of the threads coming together they're ever loosening and fraying at the edges - frustrating! Particularly so because some of the characters Krauss creates along the way are great, with interesting back stories, but the novel is either poorly organized or organized on such a vast and subtle scheme that it's almost impossible to follow. As noted yesterday, the second half of the novel mirrors the first with each of the four sections in part one getting a reprise in part two - now I'm on the part 2 section of Your Honor, in which an American writer (the one who took the desk from the young Chilean poet years back) addresses a judge (dying in a hospital? in Israel? we have met a judge in an earlier section but he's British, can't figure this out) and telling a rather long tale of how by chance she met an Israeli who looks like the Chilean poet of years back - his son? How could that be? Page by page, section by section, I like this book very much, but I can't get my mind around the design of the whole story - there are some great books that bring this multiplicity of plot off effectively - Gravity's Rainbow, for one example - but you have to put a great deal of faith in the author, you have to have confidence that you're in good hands, that the author is in full control of his/her material. I'm still interested, but not fully confident.
