The gang all faked their deaths

In order to confuse the Chiyo mother-in-law (the prisoner) (and it was Conan's idea)

After so many detectives died,

Chiyo mother-in-law hid on it and looked at the monitor and said, "It's the same as before, everyone killed each other again"

Just then

the picture on the monitor disappeared < The seventh detective (that's right) "

Chiyo's mother-in-law panicked

She went down to check

She found Conan

Conan told her where the treasure was

She wanted her to tell herself the way to escape

But she didn't intend to or leave here

So the detectives who faked their deaths came out when they heard these words

Everyone heard the shock. It was a bigger noise than that (the house was made of gold)

But everyone escaped

Chiyo's mother-in-law suddenly jumped on the plane

Kogoro jumped with her

In fact, Chiyo's mother-in-law was trying to help him escape

Otherwise, because the fake Kogoro didn't smoke, he was suspected by those detectives and thought he was Kidd.

Kidd tied her to a helicopter.
