Misunderstanding

Misunderstanding (誤解, Gokai) is the eighth chapter of Volume six and 51st chapter overall.

Plot
L and the team watch Higuchi's actions in the car from the cameras that Wedy had implanted. Higuchi wonders if Matsuda was smart enough to shred up his resume before going on television. He asks Rem, who has been following him all of this time, for her opinion. L and Light are puzzled as to why Higuchi has begun talking to himself. Rem realizes that this is all part of Light’s plan and encourages him to attempt to kill Matsuda. Light wonders who Rem is, and L suggests that it could be a Shinigami, much to Misa’s surprise.

Higuchi enters Yoshida productions and find’s Matsuda’s resume with the phony name, “Taichiro Yamashita.” Higuchi takes out the Death Note, writes the name down and leaves. Light is bewildered by these actions, but L notes that he may be preparing to do something in the car.

Higuchi returns to the car to watch TV, and after 40 seconds, Matsuda doesn’t die. Higuchi gets upset saying that he didn’t die. Baffled, the team tries to figure out when exactly Higuchi performed the killing. L wonders if writing down the name is his method of killing.

Then, Higuchi tells Rem that he wants to make “the trade.” L and the others continue to watch. Wedy, Aiber, and Mogi follow him. Just then, a police officer on a motorcycle pulls Higuchi over for speeding. Higuchi secretly writes down the police officer’s name in the Death Note, which he can see thanks to the Shinigami Eyes. As Higuchi speeds away, the police officer is chasing after him until he gets into a terrible accident.

Upon seeing this, L says that they now must assume that Higuchi can kill like the Second Kira, just by seeing a person’s face. He orders that they have enough evidence and will now attempt to capture him before he kills any of the members of the investigation team.

Conception
Ohba said the chapter's title "Misunderstanding" refers to when Light and L see Higuchi write a name in a notebook and don't realise that it is in fact the method of killing people.
