Jack looked around curiously for a week, he usually doesn't open up his senses, especially his sense of smell.

In European and American countries, and even in Asia, which has always wanted to get out of Asia and join Europe, body odor is a common phenomenon, so most people here will use antiperspirant or deodorant, and perfume is a must-have when going out.

If he dares to improve his sense of smell indoors, it will definitely be a nightmare-level encounter, but under normal circumstances, everyone around him pays attention to hygiene, as long as he doesn't deliberately distinguish it, he can barely get used to it.

"So the murderer was sensitive to a certain perfume?" Taylor subconsciously put her arm in front of her nose and sniffed it, she deliberately sprayed herself before going out today.

Red shook his head, "Perfume is an artificial scent, the victim may be a woman who does not use perfume, I suspect that the murderer may be suffering from allergic olfactory dysfunction, he can distinguish some very special smells, and fanatically pursue it, this is the motive for the crime." ”

The term allergic olfactory dysfunction is quite familiar to Jack, he had watched a Russian drama in his previous life, in which a detective with a very keen sense of smell was set up, who seemed to suffer from this disease, and this guy could smell explosives on a passenger sitting on the other side of the plane cabin.

And this detective is also plagued by all kinds of strange smells on a daily basis, resulting in an eccentric personality and has to wear a special nasal prongs when he travels every day.

This drama may be a little artistic, but the sense of smell is too sensitive, and it is really not a particularly friendly talent in Europe and the United States, Jack once read some statistics, it is said that 90% of whites and almost 99% of blacks in the world have body odor problems.

It's not that the Seris people are particularly clean and don't have this problem, but in the long process of evolution, there have been some Seris people who accidentally lost a small piece of gene fragment, resulting in serious degeneration of the apocrine glands, so these people have become a minority with almost no body odor.

Apocrine glands are mainly distributed in the armpits, external auditory canal, eyelids and navel and below, and the fatty acids and some pheromones secreted by them are excreted from the body with sweat, and under the action of bacteria, they form a strange taste similar to cumin mixed with cumin.

With the progress of human civilization, those minorities who secrete less fatty acids due to the degeneration of apocrine glands have less body odor, which makes the taste of pheromones relatively more obvious, resulting in more popularity with the opposite sex, so they have gradually become the majority in East Asia.

As a result, the number of people with body odor problems among the Seris is becoming less and less, accounting for only about 6.5% of the total population.

And Jack also found that body odor seems to be provocative, perhaps many people in adolescence, will notice that one of their favorite members of the opposite sex, after exercise mixed with sweat sour smell especially makes them feel good.

Usually in literature, it is described as the body fragrance of a girl or the good smell of a boy mixed with fresh soap, but in fact, this smell is more provocative, A can smell it, B may not notice it, let alone between people of the same sex.

European and American women pay great attention to the management of body hair in armpit hair and even in the three-point area, which is also a means to reduce body odor and make the body odor they exude more attractive.

"If you say, the murderer wanted to use chemical means uh. As Rhett said, does extracting female body odor require some special equipment? Emily seemed to have an idea.

Reed, who was reminded, stood up from the couch, "Yes, I can make a list for Garcia, he will definitely need some lab equipment, beakers, glass test tubes, a ceramic or glass container that can fit a full adult woman's body, etc. ”

Speaking of this, he was suddenly stunned again, and suddenly hit the palm of his left hand with his right hand excitedly, "I also understand what happened to the part of the skin on the sole of the victim's foot that was removed."

When I was in middle school, I did an experiment using methanol to separate chemical components, and my teacher would ask us to cut out a part of the raw material and take a pre-sample and compare it with the results, which was exactly a 2 x 2 inch square. ”

Jack put a portion of beef broth into the thermos bucket and handed it to him, "Coincidentally, you can send some late-night snacks to Garcia, she should still be in the headquarters to help you track down the whereabouts of those methanol and chloroform." ”

Then everyone took their leave, and Rossi recited a familiar passage as he left, to the effect that "only the smell of déjà vu can fully awaken the memory of the past."

Jack was still thinking about this phrase in his head when he started his routine workout, and he didn't remember it until the end of his workout, when he was in the bathroom shower, and this passage is from "Lolita" by Russian-American writer Vladimir Nabokov.

Emily, meanwhile, was helping him clean up the vegetable patch in the backyard, and the eldest sister seemed to be very interested in gardening, and liked to play with flowers and plants.

The current cohabitation of the two in the form of pure friendship is quite harmonious, although Emily occasionally jokes about Jack's behavior of stepping on two boats (she only knows two boats), but after getting along for a long time, she is quite sympathetic to Jack.

After all, it is not an easy task to be pursued by two excellent women at the same time.

"But can you change your habit of wearing shorts and running around the living room after taking a shower?" Of course, Emily also has something to do with Jack.

After exercising, Jack, who walked out of the bathroom after taking a hot shower comfortably, looked innocent, there was no one at home, he didn't even bother to put on his pants, the temperature in Los Angeles was between twenty or thirty degrees all year round, and it was naturally dried after walking around the living room twice, and the bath towel was not used at all.

Emily took a deep breath, and her nose was filled with an indescribable, but very good smell mixed with soap, and she suddenly felt that she could empathize with the murderer.

She tried to calm down, slapped Jack's chest muscles, gritted her teeth, and said, "Get dressed, or you might have one more female suitor." ”

Is this a threat? Jack couldn't help but put on a T-shirt for himself, this eldest sister is the same as Angela, the relationship is simpler, it's actually quite good to be a buddy, it's really complicated, everyone is uncomfortable.

The next day, Jack drove Emily to work in a "mammoth" as usual, but halfway through the car, he received a call from Rosie and drove directly to the Hollywood Hills.

ALONG A TRAIL NOT FAR FROM THE "HOLLYWOOD" SIGN, TWO MOUNTAIN BIKERS FOUND A FEMALE CORPSE WRAPPED IN BLUE WATERPROOF PLASTIC SHEETING, IDENTICAL TO THE THREE BODIES PREVIOUSLY FOUND.

"It's the same as before." Rosie, who lives in nearby Beverly Hills, arrived at the scene before anyone else.

"The identity cannot be confirmed for the time being, and it is likely that it is the same as before, because it has not been more than 24 hours since the abduction, so the disappearance report has not yet entered the system."

It happened to be under the jurisdiction of the Wilshire Police Department, and Jack saw a lot of familiar faces, including John and Tim.

"I think we need to speed things up." Tim walked up to Jack with a grim look on his face.

"Another girl named Anissa Goethe disappeared yesterday evening, her roommate said she went to interview for a new job, but then disappeared, did not show up for the interview and did not return home."
