Logically, it seems Saruman should have known the dispositions of the Three. After all, he was the head of the White Council, apart from his general knowledge of the Rings of Power.

That brings a question though. Assuming Saruman did know where the Three were, why, by the time of the War of the Ring, did Sauron not have that knowledge?
The latter dominated Saruman through both's use of their palantiri, but maybe Saruman kept that hidden; an example of his dealing against both sides?
