Detective Conan (名探偵コナン)

Camping, camping!

We're going camping!

Wow!

She's climbing up that cliff.

There's a river on this side.

Someone's kayaking down it.

They're so pretty.

Wait.

It's a rare mountain plant.

Don't pick it.

Okay!

Let's hurry up and go.

Aren't you going to take a panoramic shot of the city for your science project?

Now let's go.

Okay.

Mount Kumomaru Cottage Entrance

That's enough!

Huh? It's those guys from earlier.

Why do you always act like this?

You show up late and demand we cook for you!

Oh, shut up. Who cares?

Yamakura Takemi (26) Mountain Climber

Eiko-san said she'd cook for me.

Ikeguchi Eiko (23) Mountain Climber

Yeah, I said I would.

That's irrelevant.

Takemi, you always do this.

Hayashida Taro (28) Mountain Climber

Calm down, Ashizuka-san.

Ashizuka Tokunori (33) Mountain Climber

No, I'm going to let her have it.

She's always inconveniencing the group with her selfishness.

You're right.

That's why Motoki-san is dead, too.

You're wrong.

It was an accident.

I'm not so sure.

You think what happened three years ago is my fault, don't you?!

An accident? Three years ago?

Wait, Takemi-san.

I'm sorry.

I shouldn't have said anything.

Even heaven is watching the labyrinths of the world!

Full throttle reasoning skills penetrate all mysteries!

It was supposed to be a feel-good hiking trip but misfortune strikes an arguing group.

Always determining the one truth

with the body of a child and the mind of an adult,

his name is Detective Conan!

The Dark Mountain Route

"The Dark Mountain Route!"

Apparently she's sleeping at the bottom of this cliff tonight.

It seemed like they really hated each other.

I'm sure they have their reasons.

Sorry, guys.

I'm sorry you had to see that.

Hey, what's the accident that happened three years ago?

What? Oh, well...

We were part of the same club.

Three years ago, one of our members had an accident.

Takemi ran off by herself.

When Motoki went after her, he fell from the top of the cliff.

Motoki was my childhood friend.

We'd climbed several mountains together.

We were going to keep climbing, too.

But because of Takemi—

Damn it.

So we get together every year to commemorate his death.

Huh?

What's that sound?

Could it be?

Helium

That's a research balloon, right?

Yeah.

I'm sending it up to the stratosphere to collect meteorological data.

Hayashida-san, you're a weather station employee.

That's right.

For the next ten days, I'm going to be sending up my balloon every day.

I brought enough for the job.

Something smells weird.

Yeah.

Each time we increase the power, it's coated with kerosene.

Done.

Wow!

Couldn't you use one of those to fly to the peak?

That's impossible.

A single balloon can only carry five or six kilograms at most.

There!

He moves so much in his sleep.

She's still not here.

I'm going to call her.

Forget her.

But...

Sorry.

Did we wake you?

No.

This must be when Motoki-san died.

Hello, Takemi-san?

Don't wake me.

I was sleeping.

I know.

I'll offer a silent prayer, too.

Huh? Where's Hayashida-san?

He said he was going to a nearby mountain to collect data.

Ayumi-chan, what's wrong?

I had a nightmare.

What?

Really? Just look at you.

I'll cast a sleeping spell on you.

We're leaving as soon as we finish breakfast.

To the peak!

What's wrong, Genta?

Th-That.

Takemi-san's on the ground!

Conan-kun!

5:05.

Campsite Entrance

Over there!

5:45.

Takemi!

She's dead.

It can't be...

Hey, look at this.

That's her hiking compass.

Yeah.

Takemi-san!

How did this happen?

Is that a drone?

Yeah.

We're using it to search the mountains.

Way to go, MPD.

Are the three of you

the late Yamakura Takemi-san's acquaintances?

Yes.

We found a backpack

in the forest three kilometers from the crime scene.

We'd like you to confirm if it belonged to Yamakura-san.

A backpack in the woods?

That's definitely it. It's Takemi-san's.

I see.

Inside were the knife we believe is the murder weapon and an empty wallet.

The killer must've abandoned it.

Then the killer fled down the mountain after killing Takemi-san at the bottom.

Well, actually...

According to the mountain guard,

he's been in the cottage at the entrance

to the foot of the mountain since about 4 AM,

but no one suspicious left the mountain.

What do you mean?

Someone may have left the bag in the forest

to make it look as though an outsider killed her.

Which means one of us did it.

Wait.

We couldn't have killed her.

Why not?

Takemi was alive until 3 AM.

You were there, too.

Yeah.

That's when Eiko-san called her on her phone.

That's right.

The body was found around 5 AM.

Cottage

Campsite

In other words, the crime was committed during those two hours.

But no matter how much you hurry,

it takes about forty to fifty minutes to take the path down to the crime scene.

That's about how long it took when we went.

Killing Takemi-san and leaving the bag

in the forest

three kilometers away would add another thirty to forty minutes.

Since the return trip is uphill, it took more than sixty minutes.

All together, that's over 120 minutes.

It couldn't have been done within two hours.

And they were sleeping in the cottage with us.

Eiko-san was sleeping with me.

See?

Eiko and I couldn't have done it.

But, Hayashida, you...

I was surveying on another mountain!

I see.

Could we ask you a few questions

about the late Yamakura-san?

Did they really not do it?

It wasn't Eiko-san.

She definitely didn't do it.

But you saw the four of them fighting.

Shall we investigate?

What?

Yeah!

If one of them is the killer,

that means they snuck out of the cottage,

went to the crime scene and forest, and returned within two hours.

However, that's not actually possible.

But what if they climbed?

Climbed?

Yes.

Instead of taking the mountain path,

if they climbed straight up and down the cliff,

they could've done it within two hours.

Eiko-san was climbing yesterday.

No, that cliff is fifty meters tall.
