I have always considered DeLillo to be a somewhat inconsistent writer. He can be rather sloppy in one novel and yet quite brilliant in another. However, when he is at his very best, as I firmly believe he is in this particular work, it makes for an incredibly rewarding reading experience.
Apart from the basic knowledge that Oswald shot JFK and then was killed two days later by Jack Ruby, my understanding of the entire history leading up to this arguably most significant assassination was practically non-existent. Given this fact, I had no idea what was purely fictional or half-speculative and what was more based on fact. Clearly, DeLillo has taken a great deal of stale research material and woven together something entirely new, largely by simply inventing and filling in the blanks, so to speak. From what I have read of him, DeLillo has a sharp eye for conspiracy, and his fascination with this theme is in full force here, without a doubt. This novel also had a genuine sense of slow-building dread, despite the fact that you know what is going to happen throughout. It had me thinking, although they are completely different novels, of 'The Names', which happens to be one of my favorite DeLillo works. Well, now I have another.
In particular, I was extremely fascinated by the whole Castro angle of the novel, as well as Oswald's time spent in Russia where he met his wife. From the brilliant interior monologues to the richly constructed scenes involving a whole array of other characters, this complex and labyrinthine underworld of a novel was simply of the highest quality. And due to the way the plot is structured, it was probably DeLillo's most complex work at that time.
It's a five-star rating for me.
