Chapter 746 The first code was cracked successfully!

Yuya and Conan took a car and came to the castle building on the map.

However, after walking around here, not only did I find no clues, I also didn't find any clocks, alarm clocks or the like, there was no dessert shop, and I didn't see any weapons store selling swords.

On a bridge, Youya leaned on the railing and said in a depressed tone, "This is not a good way to find it. Although there are not many castle-like buildings in London, it would take a lot of time just to travel there. It is impossible to investigate them one by one."

"We still have to find a way to solve the mystery of the notice."

At this time, Yuya's cell phone rang. It was Miyano Shiho calling.

"Yuya, you and Conan haven't come yet?" Miyano Shiho asked on the other end of the phone.

At this time, Conan's cell phone rang. It was Mao Li Ran calling.

Youya glanced at it and ignored it, and asked into the phone: "We are still investigating the code in the notice letter, what's wrong?"

"It's like this, Ms. Diana is here, and Uncle Kogoro has gone to dinner with her. She asked me where you were, so I called to ask when you will be back."

"Ms. Diana is here already?" Youye was surprised. "Didn't we agree to meet at 8pm? It's not even dark yet..."

"No," Yuya slapped his head, "I was so busy investigating the notice that I forgot this is London. It seems like it won't get dark until nine o'clock this season."

"Where are you?" asked Miyano Shiho.

Yuya looked around, then looked up at the huge clock tower in front of him and said, "We are over here at Big Ben... We have walked here without realizing it."

"It's not far away. Come quickly and don't let Ms. Diana wait too long."

Yuya was about to agree.

"Boom! Boom! Boom!"

Big Ben began to ring with a huge sound, as if it would echo throughout London.

The time came to eight o'clock in the evening.

Yuya looked at the roaring Big Ben, and a flash of lightning flashed through his mind.

He said excitedly, "So that's it. The roaring bells are indeed referring to Big Ben. My reasoning was correct."

A question mark appeared above Miyano Shiho's head: "What happened to Big Ben?"

Yuya explained: "I figured out the location referred to by the first line of the notice, and it's the same as my reasoning. But..."

He looked around but didn't see anything special.

Could it be inside Big Ben?

"Mio, please apologize to Ms. Diana for me. Just tell her that I have an important case to investigate. As a detective fan, I believe she will understand."

"It should be enough to have Uncle Kogoro over there. Even I can't match him in bragging."

Miyano Shiho glanced at Kogoro Mori, who was bragging about his experience in solving a case to Diana, and couldn't help but nodded. It was indeed true.

Moreover, because Kogoro Mori didn't need to draft his bragging, he had ready-made materials and spoke very fluently, which made the translator next to him very tired.

Yuya hung up the phone and looked at Conan, who had just finished his call.

Yuya raised an eyebrow at Big Ben, and Conan responded with a tacit smile.

The two walked towards Big Ben together.

"I wonder if the clue is hidden inside Big Ben or outside?" Youya asked casually.

"Not sure yet..." Conan answered while looking around.

Suddenly, he saw an arrow painted with white paint on the ground, pointing behind them.

"Yuya, look at this." Conan squatted down, reached out and touched the arrow, then rubbed his fingers and said, "It looks like it was painted on recently."

Yuya raised his eyebrows. He hadn't even noticed the arrow just now, but Conan found it first. He couldn't help but mutter, "Sure enough, being small has its advantages."

Conan didn't hear what he said clearly, so he asked, "What did you say?"

"Nothing." Youye shook his head quickly.

A question mark appeared above Conan's head: "I always feel like you're thinking about something very rude."

"How is that possible!" Yuya laughed, patted Conan's head and said, "Then let's follow this arrow and have a look, maybe we can find something."

The two followed the direction of the arrow and came to the bridge. When they reached the center of the bridge, they suddenly saw a drain without a manhole cover.

"Who is so uncivilized to take away the manhole cover? What if a child falls down and gets his foot stuck?" Youya complained. Just as he was about to look for the manhole cover, he suddenly found a line of words written on the side of the drain.

He quickly walked over and squatted down. Conan also came up and read: "The Valler of Fear. The Valley of Fear?"

Yuya touched his chin and said, "Come to think of it, do you remember that Sherlock Holmes has a book called "The Valler of Fear"? "

Conan was stunned for a moment, then nodded and said, "Of course I remember, that was the third novel about Sherlock Holmes. But why is the name of the Sherlock Holmes novel written here?"

"Hmm..." Yuya pinched his chin, "Is there anything about bridges in this novel?"

Conan frowned: "That's a long novel. Even I can't remember such details..."

Yuya looked at the words, his sight suddenly fell on the drain, and he murmured: "Why did you take away the manhole cover? If it was just to draw attention to this line of words, there would be no need to go through so much trouble... Wait, drain, water..."

He looked up through the railing at the Thames: "And the river..."

"I see." Youya suddenly stood up.

Conan was startled and looked at Yuya in surprise. He had just vaguely thought of something, but Yuya had forgotten it all in an instant.

Yuya looked around and soon found what he wanted - he could clearly see a rope tied around the lamppost.

He walked over and looked down, only to see the rope hanging all the way down into the river.

"This is..." Conan also saw the rope and his eyes widened immediately.

"If something heavy disappears at the water's edge, then something must have sunk into the river. This is definitely a correct conclusion." Conan said the line that Sherlock Holmes once said in the novel, "You think so too, right?"

Yuya smiled slightly: "Yes, but I thought of it before you."

Conan said: "If you hadn't stood up suddenly and scared me, I would have thought of it before you!"

Yuya shrugged his shoulders and said, "You had already lost at that time." As he said that, he ignored Conan who was jumping in anger, reached out, grabbed the rope and started pulling it up.

Soon, the heavy object hanging on the rope was pulled up. It was the missing manhole cover of the drainage outlet.

On the lower right corner of the manhole cover, there is a letter A engraved.

The two looked at each other and smiled at the same time——

"found it!"
