The Priory keystone.
Take the keystone.
"Actually," Langdon replied, feeling a tingle of excitement ripple through him, "the keystone is believed to have been created by the Priory sometime in the past couple of decades."
For years he had traveled to cathedrals and churches all over France, paying for special access, examining hundreds of archways beneath rose windows, searching for an encrypted keystone.

I have the keystone.
Despite Langdon’s assurances that the keystone had nothing to do with her past, Sophie still sensed something deeply personal entwined within this mystery, as if this cryptex, forged by her grandfather’s own hands, were trying to speak to her and offer some kind of resolution to the emptiness that had haunted her all these years.
The British historian hoped the touch of the Grand Master’s cryptex would make Langdon fully grasp the magnitude of its contents, coaxing his academic curiosity to overwhelm all else, forcing him to realize that failure to unlock the keystone would mean the loss of history itself.

Rémy had asked the Teacher less than half an hour ago, upon getting orders to steal the keystone.
Now, however, here in the Temple Church, with Langdon threatening to break the keystone, Rémy’s future was at risk.
His hands felt damp on the keystone as he waited for Rémy to finish tying and gagging Teabing in back with the rope they had found in the trunk.
You must believe that I would much prefer to receive the keystone from you—a man of God rather than a criminal—but Rémy must be dealt with.
For this reason alone, I will ask Rémy to bring me the keystone.
Rémy held up the keystone like a trophy.
One way or another, the keystone was coming to Château Villette.
Rémy’s orders had been clear—stay out of sight while Silas recovers the keystone.
Unfortunately, Langdon’s threat to smash the keystone on the chapel floor had caused Rémy to panic.
This recovery mission, as Rémy had described it, was to be clean and simple: Enter the church, take the keystone, and walk out; no killing, no struggle.
Silas was supposed to break in and steal the keystone from you in Château Villette—thus removing you from the equation without hurting you, and exonerating me from any suspicion of complicity.
It would prevent Saunière from persuading Langdon to keep quiet, and it would ensure that once the keystone was in Teabing’s hands, Langdon would be in Paris for recruitment should Teabing need him.
We have done well," Rémy replied, laying the keystone in the Teacher’s eager hands.
