"Missing something?"

"Yes, one thing was overlooked." Jiang Shaowen said as he walked, "We have been focusing on the tools used by the murderer to commit the crime, but the cutlery knife used in the crime is a cutlery knife, even if the people in our town are not used to using knives and forks, but every household still has reserves, even if it is lost, it is not easy to investigate, so we directly gave up the idea of finding the tools of the crime." ”

"But we can't find the tools to commit the crime, we can find the cleaning tools."

Old John suddenly realized: "You mean that we are now going to find the murderer's cleaning tools?" ”

"That's right." Jiang Shaowen nodded: "The murderer used pig blood just to imitate the Mar family, which was the first scene of the crime, but we now know that this is the murderer's full set." ”

Old John followed, "Because the murderer had to carry the body from the first scene to Mar's house, he needed cleaning tools to wipe the marks he left behind because of the transportation!" ”

Jiang Shaowen said approvingly: "Right." ”

Van Wo offered a different point of view: "Then why didn't he hide in the town?" There are more corners in the town, so it should be easier to hide, huh? ”

Jiang Shaowen shook his head and said, "I've looked for it, but I don't have it, and that thing will emit a stink if it is not cleaned up, so the water source is the only choice." ”

"Then don't wait any longer, Fanwo, you take George on horseback, I won't go, otherwise it will be delayed."

"That's fine." Jiang Shaowen nodded, "Fanwo remember, bring the dog, I have a lot of use." ”

The total area of the olfactory epithelium in dogs is 170 square centimeters, and its cell density is 100 times that of humans.

The dog's sensitive sense of smell is mainly manifested in two aspects: first, the sensitivity to smell; The second is the ability to distinguish smells. Sensitivity varies depending on the type of taste, and is about 1,200 times that of the human sense of smell.

The dog's nose can distinguish about 2 million different scents, and it also has a highly analytical ability to pick out the kind of scent it is looking for from many mixed scents. Dogs can perceive odors at the molecular level.

"That's why I'm asking you to bring Blake with you." After Jiang Shaowen finished speaking, he looked at Fan Wo with a confused face, and said in a different way: "In other words, I am actually looking for your dog, and you are just your dog's foil." ”

"Ugh."

Without waiting for Fan Wo to reply, Jiang Shaowen said, "Did I let you bring the things you brought?" ”

"Well, brought it." Saying that, Fan Wo handed the cloth bag and bell containing the pieces of meat to Jiang Shaowen.

Jiang Shaowen held a piece of meat and a bell in one hand, and a bloody rag in the other, walked to the black dog's side and squatted down, touched the dog's head and said, "Next, buddy will rely on you." ”

After speaking, Jiang Shaowen handed the bloody rag to the side of the dog's nose and let it smell it, and at the same time shook the bell, then fed him another piece, then let him smell the rag, and then rattled the bell and gave it another piece of meat.

Looking at Jiang Shaowen's efficiency in feeding the dogs, Fan Wo secretly breathed a sigh of relief, fortunately, he listened to George's words and cut the meat into relatively small pieces, otherwise George's feeding efficiency would not last long for his own family.

Finally, seven or eight times in a row, the black dog has understood that there is no need for Jiang Shaowen to hand over the rags now, as long as Jiang Shaowen rings the bell, he will smell the rags, and then go to Jiang Shaowen's other hand to receive the meat to eat.

"Hmm." Jiang Shaowen was very satisfied with the fruits of his labor, he buried the rags in his hand in the soil, and then watched Blake shake the bell.

Blake was very smart, he threw away the soil by himself, took out the rags, sniffed them in front of Jiang Shaowen, and then licked Jiang Shaowen's other hand holding meat.

Jiang Shaowen fed another piece of meat to Blake, "Van Wo, you go and bury this cloth next to the tree in front." ”

Fan Wo went to bury the rags, Jiang Shaowen held Blake's head and didn't let it see, and after a while, Fan Wo buried it, Jiang Shaowen let go of Blake's head and shook the bell in his hand.

Blake subconsciously went to Jiang Shaowen's hand to look for the rag, but the rag was obviously not there, and then Blake began to dig the soil, but there was no trace of the rag inside, and it was confused for a while.

The search was at an impasse, and Fan Wo had been standing on the side with a wait-and-see attitude and watching what Jiang Shaowen would do next.

Jiang Shaowen shook the bell in his hand, put the hand that was holding the rag before in front of Blake's nose and let it smell it, then pointed to the ground, and approached little by little to the place where Fan Wo buried the rag before.

But Jiang Shaowen didn't go to the tree at once, but spared a big circle first, and when Blake was about to run out of patience, Jiang Shaowen guided Blake to the tree.

Blake smelled the familiar smell, threw away the dirt very excitedly, took out the rags buried deep inside, and sniffed it in front of Jiang Shaowen.

Jiang Shaowen patted Blake on the back with one hand, and fed it a piece of meat with the other as a reward.

Then Jiang Shaowen did five or six more trainings, and the distance was getting farther and farther each time, and in the end, without Jiang Shaowen's guidance, Blake himself brought the rags back and handed them to Jiang Shaowen.

Van Wo felt a novelty about this, and then there was magic, until the last surprise, he never thought that Blake would cooperate so perfectly with Detective George, this dog was left to him by his father, and before his father died, because of Van Wought's stubbornness, he did not learn how to train a hunting dog at all, so the hunt has always been a unilateral action of Blake.

The cooperation between the hunter and the hound was miserable, and for the first three days Blake was anxiously jumping and barking, but Van Wo himself was at a loss and didn't know what to do.

Looking at Fan Wo, who was stunned on the side, Jiang Shaowen smiled, "Your father trained this dog very well, it can be called perfect." ”

Van Wo was a little embarrassed, "Hmm. ”

"Since it's successful, let's give it a try." Jiang Shaowen took Blake and walked in the direction of the creek.

The place where Jiang Shaowen trained Blake before was not far from the creek.

In the same way, Jiang Shaowen did not ask Blake to look for it as soon as he came up, but first came to a few drills before Blake began to look for it.

Blake is an old hound, very steady, Jiang Shaowen was worried about his patience at first, but now it seems to be completely superfluous.

Blake is a qualified hound by nature, intelligent, alert, and patient.

But no matter how powerful the hound is, it is also based on the presence of prey, Jiang Shaowen took Blake to search along the creek for a long time but did not find the slightest.

Blake was inevitably a little disappointed, and let out a whining sound, Jiang Shaowen hurriedly patted Blake on the back, buried a rag for it, and asked Blake to find it, and took the opportunity to reward it with a piece of meat.
