Query: Gideon's Spies-I've read better

Gideon's Spies, while not as well written as By Way of Deception, still reveals Mossad's ruthlessness. Gordan Thomas seems to derive a sick pleasure in describing assassinations, deceit, espionage and taking advantage of the US that characterize Israel's secret intelligence agency. The author is in awe of this corrupt organization. If you can get past that, the events seem factual and are corroborated with other publications.By Way of Deception is a far better book. It has many more organizational details and each horrible incident unfolds like plot of a good mystery novel. The author, Victor Ostrovsky, is a Jew who had high expectations of a moral code of the Jewish state, who was bitterly disappointed upon entering the secret world of Israeli intelligence.
