McCroft changed the subject: "I'm afraid you're not very interested in these things, not to mention that you have to go out on errands for this kind of case." Pen ~ Fun ~ Pavilion www.biquge.info"

Sherlock turned his head in displeasure, and McCroft smiled triumphantly as he picked up a document and handed it to Sherlock.

Sherlock shook his bowstring and looked at Mycroft in surprise, as if to say: Are you stupid, I said that I would not take this case, why did you still give me the information.

Mycroft was so angry by Sherlock's performance that his teeth hurt, and he turned around and handed the information directly to Han Yiren and said, "Andrew West, a civil servant, was found dead on the tracks of Batshey Railway Station this morning, and the cause of death was a heavy blow to the head. ”

John interjected and asked, "Is that a suicide by jumping off the rails?" ”

Han Yiren shook his head and said, "This inference seems to be logical, but what? ”

McCroft gave Han Yiren a deep look and continued: "The Department of Defense is developing a new missile defense system, called the Bruce-Pattington program, and the content of the plan exists on a memory stick. ”

"That's not a clever trick."

McCroft was speechless: "There are a lot of backups, but they are classified, but they are missing now." ”

"Highly classified?" Han Yiren was looking at the information and asked without raising his head.

"Of course, we think West took the memory stick, so we must not let it fall into the wrong hands! You've got to get it back, Sherlock. ”

Sherlock gently wiped the bowstring, completely ignoring McCroft, who shrugged his shoulders and smiled, "You think it through." Then he shook hands with John and Han Yiren and left.

As soon as Mycroft left, John began to ask questions, but none of this had much to do with Han Yiren, and his attention was completely focused on the information in his hand at this time.

"Whew~"

After a long time, Han Yiren finished reading the entire information, and after reading it, he couldn't help but want to sigh at the strength of the British intelligence department, and the information in his hand completely included everything from West's childhood to adulthood, relatives, classmates, friends, lovers, lovers' relatives, friends, etc.

"How? Are you interested? ”

Sherlock had just finished a phone call, and it was clear that there was good news on the phone, and he was in a good mood at this time.

"No, how could I be interested, I'm just impressed by Mi5's ability to gather intelligence." Han Yiren shook his head with a smile and handed the stack of materials to John.

MI5 is the British counterintelligence and national security service, which works under the leadership of the Home Secretary but is not subordinate to the British Home Office, and is responsible for combating serious crime, military separatism, terrorism and espionage in the country, while MI6 is responsible for external national security duties.

Sherlock glanced at Han Yiren with a smile, got up and said, "Let's go, the case is here." After walking a few steps, he suddenly looked back at John and said, "Big case, are you coming?" ”

"Come on! Why don't you come! John, who had planned to look at the information, put it away and quickly got up and followed.

Han Yiren took a taxi and squeezed in, because the taxis in London are all miniature types, the tallest Han Yiren shrunk his neck and complained: "Teacher, you don't plan to take taxis all the time, do you?" When to buy a car and drive it yourself. ”

Sherlock glanced at Han Yiren, and wordlessly turned his head to look out the window, Han Yiren saw that Sherlock didn't care about himself, and shrugged his shoulders and learned to look at the scenery outside the car window.

Soon they arrived at their destination, the London Police Station.

Their old acquaintance, Lestrade, was already waiting at the door, and after seeing the three Sherlocks arrive, they greeted them briefly, and led them straight into the police station.

"You've always liked interesting cases, and it's clear that you must have liked it, and it's a bombing." Lestrade said as he walked.

"Gas leak?"

"No, it's not, it's just an illusion created by the murderer, the place is all blown up, and only a safe remains."

Lestrade said, pointing to the open safe in his office, taking out the only envelope inside, and said, "This safe is safe, and inside is an envelope with your name on it." ”

Sherlock took it and looked at it and asked, "You didn't open it?" ”

"No, it says you take it, doesn't it? I'm a police officer, but I can't break the law. Lestrade raised an eyebrow and joked, then continued: "We have already checked this envelope and have not tampered with it. ”

Sherlock was silent and walked to the light with the envelope to look at it, and then beckoned Han Yiren over and handed it over, "Tell me about it." ”

Han Yiren first glanced at Sherlock suspiciously, making sure he wasn't joking before taking the envelope and looking at it, and when his attention was focused on the envelope, the school palace in his mind began to provide him with all the knowledge that could be used at the moment.

Sherlock's full name is handwritten in a blue pen on the front of the envelope, judging from the smoothness and thickness of the handwriting, it should be a Parker flat top Doover series iridium pen, the font should be a woman's handwriting, and the paper of the envelope is very particular, using bohemian paper from the Czech Republic.

Han Yiren told Sherlock what he had discovered, and then his unfazed eyes revealed a hint of admiration and appreciation, and he took the envelope and asked Lestrade: "Do you have fingerprints?" ”

After seeing Lestrade shake his head, he took a paper cutter and opened the envelope under the gaze of everyone, and inside was a pink mobile phone, which looked like the mobile phone in the pink study written in John's blog. "Broken.

"Do you really not know that the Earth revolves around the Sun?"

Seeing that Sherlock was exposed on the spot, the initiator John was obviously a little embarrassed, opened his mouth and couldn't speak, and finally Han Yiren opened his mouth to solve the siege: "What the teacher remembers in his brain is the information needed to solve the case, and these common-sense things are all done by me, and I have a specialization in the art industry." ”

Everyone smiled again at Han Yiren's sophistry and passed, and Sherlock continued to explain himself: "This is a brand new phone, although some people try their best to make them look the same. ”

After fiddling with his phone for a while, the phone immediately emits a voice text message, first four Greenwich chimes, and then a photograph taken inside the house.

Lestrade leaned forward to look at it, as if complaining and asking, "What the hell is this?" Greenwich chime and a photo of a real estate agent? ”

Han Yiren glanced at it when he heard this, his body shook slightly, and he said in disbelief: "Teacher, this is the basement where we live!" ”

"Are you sure?" John's eyes also widened and he confirmed with Han Yiren.

Han Yiren nodded, when he first moved into 221B Baker Street, the attic had not yet been cleaned up, but he had lived in the basement for several days, how could he not recognize it.
