This is so much more than the story of the massacre and the manhunt. The story starts before the end of WWII, which it has to, to give the reader an understanding of how events built up. It is written by two Israelis, so there's undoubtedly a built-in bias, but they're not trying to hide who they are, so any intelligent reader is going to take that into account. With these events, bias is not something that can be avoided in any case, so I'm at least glad to know which way it's likely to be slanted. Even with that in mind, I think the authors made a reasonable attempt to present the events, as they know them, as even-handedly as possible. One can even detect a hint of sympathy for the man who masterminded the murders of the Olympic team, since he seemed to have tried in his youth to escape the "destiny" everyone pushed on him of following in his terrorist father's footsteps.
