William sleeps until 5 p.m. when he gets up, he puts on his coat and goes to the restaurant of the hotel to have a meal. When he orders a good meal, he sees some travel brochures hanging on the bookshelf of the restaurant. He picks up a book and walks back to his seat. He turns it boring.

Looking through William's article, he saw an introduction to Roslin Cathedral in Edinburgh, Scotland, which introduced the origin and history of the church, as well as the symbols and emblems of various sects.

William was surprised to find that there was a symbol of the Priory in the atlas. Suddenly, the words in the Oxford Ordinance came to his mind: "the Holy Grail under the old Roslin is waiting.".

"Damn it, I didn't expect that William would know where the Holy Grail was right away with this sentence combined with the picture book in his hand." William pointed to the waiter and ordered the hotel to book a ticket to Edinburgh. He wanted to go there overnight.

Half an hour later, after dinner, the hotel attendant just came over and said, "Mr. Devonshire, your plane is ready to take off at any time.".

"Thank you" William gave the waiter a tip of 20 pounds and then got on the bus provided by the hotel and went directly to the airport. He ordered a small private plane that could take off at any time.

At 9 p.m., William came to a four seasons hotel in Edinburgh and had a drink, so he took a rest.

But William didn't know that when Sophie took LAN on the plane, he accidentally saw William in front of the platform glass on the second floor who got out of the car and went to the private plane. Sophie didn't give up. Sophie used beauty to set up an airport manager friend and learned from him that William had ordered a plane to Edinburgh.

They soon decided to go with him, but they didn't have any money. They had to fly to Edinburgh on a plane at 12 p.m., and when Sophie and Langdon came out of the airport at more than 1 a.m., William would have been asleep.

Sophie looked at Langdon and asked, "this is what we do now, Langdon.".

"I kept thinking about why William came to Edinburgh, until I saw this on the plane." Langdon took out a tourist atlas of Edinburgh and turned to the page of Roslin church for Sophie to see.

"What does this mean?" Sophie said

Langdon said with a smile, "remember what tibin said? The Holy Grail under the rose. Roslin church is built on the meridian line, and the symbol of the meridian line on the map is the rose. The Devonshire family must have some hints about the Holy Grail, but William didn't understand it before. When we were studying the keystone at tibin's house this morning, William told us that he was hungry and asked us if we would go together, remember? ”

Sophie nodded, "we were studying the keystone. We had no time to talk to him, so we didn't go. What's strange about that?"

"yes, it's very strange. William called us twice at that time. Now I think William didn't know why he had guessed where the Holy Grail was. And did you find that when Silas rushed to tibin, William rushed into the reference room It's too fast. Tibin and Silas just fell to the ground. He rushed in with a gun in his hand, just like he knew Silas would get rid of the tape on his hands and feet. He was waiting in the data room all the time. " Langdon said,

"Langdon, it's like that when you say that, William. It's like he's really waiting in the data room all the time," Sophie said in surprise.

"Yes, now I think William should have known the whereabouts of the Holy Grail at that time, so he didn't feel any pain at all when the keystone was broken and the paper inside was destroyed. I was a little suspicious when I saw him at that time.

But I always thought that William was determined to save tibin. Now I recall that there was still some joy in William's eyes at that time. The most desirable situation for him was that the keystone was broken and the map inside was destroyed. Then he was the only one who knew the secret of the Holy Grail in the world.

"God!" Sophie suddenly exclaimed, "that's not to say that William went out When I was young, I knew that Silas would break away from the tape, and deliberately reminded us twice to ask us to go out together, leaving only tibin.

At that time, William didn't care about the safety of tibin at all. Maybe he just wanted to legally shoot Silas when he was holding tibin

Sophie covered his mouth with both hands: "God, because Silas threatened him with his family, William didn't give up killing Silas, just because I blocked William's shooting angle at that time. He didn't shoot at the first time. Instead, Silas caught the chance to hold tibin and hide behind tibin's body, so that William didn't have the chance to shoot? ”

Langdon thought for a moment, nodded and said: "it should be like this. Normal people only need to say once if they want to have a snack. William is a smart man. He won't say it again after we explicitly refuse, but we were all immersed in the keystone code cylinder and didn't pay attention.

It seems that William is not a completely cold-blooded guy. He knows that Silas will break free, worried about our safety and told us to go out.

"God, William is really a man who will pay back. Just because Silas threatened him, he wanted to kill him. In order to kill Silas legally, he didn't care about tibin's safety at all.

God, William is too dangerous, Langdon. You said that if William knew we were coming to Roslin church, he would not kill us. "Sophie held Langdon's arm nervously.Langdon was said by Sophie that he was nervous. He didn't know if William would really kill them both. "Otherwise, let's go to Roslin church now"

"but at this time, the church is closed. We can't get in without the key, and if we are found by the church people, we will be in prison. There are many antiques in Roslin church "The police will think of us as thieves," Sophie said.

"Why don't we call William now? I'll go to see him alone. You're watching us from a distance with a camera. If William wants to kill me, you should call the police immediately and then leave, so that I can say that you're recording him in the dark with a camera and calling the police, so that he doesn't dare to kill me." Langdon volunteered

Sophie thought for a moment and said: "I'd better go. After all, my grandfather is the elder of the Priory and the guardian of the Holy Grail. I'll go to him for a reasonable reason. William may not want to kill me"

seeing Langdon's hesitation, Sophie immediately decided: "let's do it, Langdon. William probably won't kill me, so you don't have to."

Langdon thought: "we'll meet William in the airport hall. We'll buy a camera first. When William comes, I'll stare at you on the second floor with my mobile phone and camera. As soon as he wants to take you out, I'll yell and bring in the airport police.

"OK, that's it. I'll call William." Sophie picked up the phone and called William.
