Why didn't Saruman go to the Shire to take the Ring?

Indeed. Sauron trusted Saruman to bind the Rohan army, preventing it from helping Gondor, he trusted him to spy on the Wise etc. But I think Sauron realized that this alliance would not hold if the Ring were in the balance. That's why he wasn't really angry at Saruman at the end of 3018, when he finally learned of his treachery from the nazgul upon their return. Or at least he decided to keep quiet about it, still upholding the useful alliance as long as it suited him.

He was maybe exaggerating, or simplifying things, it was, from my point of view, rather a "metaphorical figure" from him. Simply put: I do not believe Saruman meant to say anything, not even that he slipped anything about his real intentions with the Ring; and at the same time, I do not believe that the WK ever thought of it as something like that. Simply, a normal dialogue.

I have to disagree. Saruman should have realized, that even if at the moment his Voice™ worked with the nazgull, later, if something slipped, his "innocent" words (uttered in front of Nine witnesses) would be remembered and used as evidence against him. And it was exactly what happened later. It was a pretty dangerous path he was threading.

On a tangent, the more I think about this Isengard scene, the less "normal" it seems to me.

First of all: why did Sauron send the Nine to Saruman if he was supposed to have direct contact with him via the Palantir? Sauron believed that Saruman knew the location of the Shire, so why not ask the Wizard directly? The explanation must be that by September 3018 Saruman had not used the Palantir for a long time. It seems that, after his failure to turn Gandalf to his side, he sat there in fear and doubt and more and more became inclined to drop everything, and to repent. That's why maybe he didn't go to the Shire. He almost repented, when the nazgul actually came (UT), but it was too late, Gandalf was gone.

Second. OK Sauron sends his most trusted servants to his faithful ally Saruman. Instead of showing warm welcome: blowing trumpets, sending forth uruks with flowers etc., Saruman churlishly keeps the Nine at the gates and uses the intercom. Well, maybe the nazgul themselves were not so looking forward to feather beds of Isengard, but their horses certainly could use some good fodder and grooming. Such a rude reception was really unseemly when dealing with the most high-ranking Mordor officials. - Again, I think it reflected Saruman's current state of mind: he most regretted his hasty alliance with Mordor, hoped for reconciliation with Gandalf and didn't want to broadcast his alliance with Mordor before the eyes of Gandalf.

Third. Why did Saruman started speaking about the Ring at all? Nobody asked him about it, only about the Shire. Why reveal his knowledge of the connection? The wish to impress the nazgul with his wisdom seems a bit childish. Perhaps his words (the first part of the conversation in The Hunt version C) were meant more for Gandalf than for the WK? The message to the Grey wizard would be "see I know where the Ring is, I know where the Shire is, but I tell the nazgul nothing. I can still be trusted."

And with the Free Peoples, he could surely get suspected. After all, Gandalf surely won't just disappear along the road - that would be awkward by itself (unless he met the Nine themselves). Then, at least some people would know that Gandalf headed to Isengard - now how comes he disappeared just on this particular way? And what more (and mainly), how did Saruman know where to look for the Ring, when Gandalf never arrived to Orthanc at all? Where did Saruman learn about "the Shire", or even about "Baggins" having anything to do with the Ring? No, really, that won't work. (And at least for Galadriel, Saruman would be definitely unmasked at this moment - she never trusted him.)

Perhaps you are right. It was a huge risk - and Saruman was too chicken-hearted to take it.

Moreover, there was another factor, not yet discussed in this thread - Faramir's and Boromir's dream.

[Saruman] believed also (knowing of the oracular dream-words and of Boromir's mission) that the Ring had gone and was already on the way on Rivendell. UT, Hunt for the Ring, version C

Now the oracular dream made it clear that the Ring would eventually find its way to Rivendell:
Saruman was a Maia, he had an inside knowledge of the Music, he knew who had likely sent the dream. Saruman had reasons to believe that whatever he may do, he would be unable to change what had been ordained. So-why even try?
