[Lord of the rings] What happened to Saruman after the events of Two Towers?

Since he is one of the Maiar, did he expect to be regenerated like Gandalf was? Or did his defection to Sauron doom him to the same fate?

Saruman eventually escaped the tower, and made his way to, of all places, The Shire, with Wormtongue and some lackeys along for good measure.

They take over the shire for a while, until Frodo, Sam, Merry and Pippin return, raise the Hobbitry in Arms, and drive them out.

Ultimately, Saruman is killed by Wormtongue stabbing him, before Wormtongue is slain by Hobbit arrows.

Following this, his spirit was blown away on a gust of wind, and was denied entry into Arda, cursed to roam as a malicious, but ultimately harmless, spirit.

This is all available through the Red Book, called "The Return of the King," graciously transcribed from the original sources by Dr. Tolkien.
