Late at night, everything is silent.

In the office of the Criminal Investigation Brigade of the Public Security Bureau of A City, a gentle man sat on a chair next to the desk with his legs folded, holding a half-lit cigarette between his long fingers, and his eyes under the gold-rimmed glasses stared at the identity information of the person on the big screen in front of him.

Li Ningqiao, female, 18 years old, height 158, senior year of high school, cheerful personality, middle to high grades, parents have been working outside for many years, living with grandma, missing for a month and 20 days, the reason is unknown.

Ke Yating, female, 18 years old, 162 tall, senior in high school, squeamish personality, medium grades, parents are the bosses of a third-rate company, the family is good, missing for half a month, the reason is unknown.

This is a very bizarre disappearance, the two seem to have disappeared from the world, disappearing from the school, first of all, the place - the school, without causing unnecessary panic, he visited the subject teacher of the two missing girls, but did not get any useful clues.

The second missing girl went to the Public Security Bureau to file a case one day after the final exam when her parents could not be contacted, Ye Yantuo looked at her final exam papers, and the six subject test papers were complete, indicating that she successfully completed the last subject, and it can be speculated that she disappeared after taking all the subjects.

However, when he checked all the surveillance of the school, but did not find her, if it was a kidnapping, who would be so familiar with the school's surveillance location? Perhaps there is another bold speculation...... It was Ke Yating who avoided the monitor herself, so why did she avoid the school monitor and what did she do? Where does she want to go?

In the smoke, Ye Yan tilted his head back, his eyebrows furrowed, and he imagined the movement trajectory and mental activity of the two missing girls in his mind, and all kinds of speculation could slide in his brain like a slide, until the smoke burned out and his fingers were burned, and he didn't open his eyes.

Putting out the cigarette butt in the ashtray on the table, he slowly got up, took one last look at the screen, then turned off the power, picked up the coat on the chair and put it on his hand, turned around and walked to the door and opened the door.

From time to time three or five people walked down the hallway, and he walked outside to the large open office, where a young male police officer was teasing the police dog sitting obediently on the ground.

"Nick! The performance was awesome!! The young officer took out a piece of jerky from his pocket and rewarded it with the dog.

Ye Yan happened to pass by, inadvertently looked at a person and a dog, and was about to continue walking, when the young police officer saw him, he immediately straightened up and saluted him with a standard military salute.

"Ye Tesuke!" Ye Yan is a criminal psychology expert specially dispatched by the province to assist Zhang Wenfei in investigating and solving the case, so most of the members of the criminal investigation team call him a special assistant.

Ye Yan smiled and looked at the obedient police dog behind him, "Nick has made a meritorious service?" ”

"Nick has a very good nose and helped us successfully catch several criminals who were hiding drugs in their cars." The police officer explained with a smile and happily touched the police dog's head, "I'm rewarding it with two pieces of jerky!" ”

Hearing this, Ye Yan couldn't help but smile, and also stepped forward to touch Nick's head, and the moment his hand was placed on the top of his head, a figure quickly flashed in his mind, and the hand stroking Nick's dog's head suddenly stopped.

School, woods, the girl who came out of the woods with Hiromi in his arms, Ye Yan's eyes were deep, and he suddenly remembered the dirt on his paws that he didn't care about when he hugged Hiromi, a coincidence or an accident?

"Immediately let someone notify Team Zhang and the people from the forensic department to meet up at Hengchuan Middle School, and you take Nick with me!"

Ye Yan immediately decided to take someone to Hengchuan Middle School, whether it was a coincidence or an accident, he would not let go of any possibility, not to mention, he had already affirmed that eighty percent of the first missing girl had been killed.

A chill flashed through his eyes under the lenses, and he only hoped that she had nothing to do with this case, otherwise......
