Sherlock fan - Wrong

Molly ate some risotto alone at home, and then started the crossword puzzle she saw in a magazine today.Around nine o'clock, John and Sherlock came back, bringing John's new girlfriend Sarah with them.The three of them had just returned from the theatre, an awkward threesome that only Sherlock could have done.

Jasmine rummaged through the kitchen for a long time, but still couldn't find any treats for guests, so she could only set out some punch wine and a few biscuits to entertain Sarah.

Jasmine listened to Sherlock and John talking for a while before realizing that they were not going on a date at night, the circus was the gangster they were looking for, no wonder that man could flip through the window like Spiderman.

Jasmine looked at the code they were deciphering and asked: "These seem to be some numbers, ancient Chinese variant characters?" Jasmine took it and took a closer look: "These numbers are codes? Each pair of numbers represents a word."

"how do you know"

"Two words have been deciphered, here."

"John, look here, Su Lin from the museum started to help us decipher it, but we didn't see it! We have to find the end of the sentence." Sherlock was about to leave them and run away again.

"Where are you going?" Jasmine yelled

"To the museum restoration room! It must be right under our noses."

"What?" Sherlock ran far away before John realized it.

"Book, John! That book! The one who broke the code! Su Lin used it to decipher it when you ran around the exhibition hall, she started to decipher it. It must still be on her desk." Jasmine patiently explained: "That should be the book. It is a very common and common book, everyone has it, it is readily available, and it must cover these words, there are numbers, there are..."

While talking, Jasmine unconsciously flipped through the pile of books they were looking for last night.When she turned to the street map of London, she couldn't help shouting, which startled the young couple: "I see, I understand!" Jasmine rushed out the door, hoping to catch up with Sherlock who had just left.

Jasmine quickly found Sherlock who was squatting on the side of the road, "I know what book it is, it's..."

"London street map!" the two said in unison again.

"900 million hosta dragon cave black tramway"

"Ah, I see. They're telling their friends all over London what they're looking for, and telling them where to connect." Jasmine exclaimed

Sherlock nodded in approval, and had a new understanding of the pretty landlady.
