Please wait!


Is anyone home?

Is there anyone home?

Can I come in?

Please, I am a foreigner.

And I'm lost.

I know someone's there.


Please, I need help.

This is completely new for me, professor.

I simply can't imagine

how a expert on insects...

...could be so helpful for the police.

Would you please explain that

more detailled.

Of course. You can't see the

connections on first sight.

When I decided to specialize

in animal cadavers, ...

...I did not have the least idea of that.

John, do I really have to listen to that again?

Oh yes, just as you had to

on the first murder case.

You came to me because

you did not know how to go on.

We solved the case together.

When a dead body is exposed to nature

it will be eaten by insects sooner or later.

You naughty girl

Where did you find that?

You could hurt yourself.

It is sharp.

It is not a toy.


And who, may I ask, put it out there?

Don't you ever play with this again.

I forgot to introduce you... this is Inga.

She's my nurse.

If I pick out something with

my laser she'll bring it to me.

She's also my friend, too.

Aren't you?

But she is a very good nurse.

Cadaver-eating insects are

divided into eight groups.

These eight groups of insects come

to the corpse one after the other.

And this only in certain

moments and at a precise time.

Never sooner and never later.

We call them the eight squadrons of death.

First, the common fly comes to the

rotting corpse and lays its eggs.

This is the beginnig of the cycle.

Each group of insects stays for exactly fifteen days.

So, you have to multiply fifteen by eight.

The number of groups.

This equals four months.

Correct. In this case the cycle seems to be complete.

Yet, it is already in the second generation.

From this we may conclude that

this head is rotting for eight months.

By calculating and determining the number,

the look and the kind of the insects, ... can find out the exact date of death.

or of the murder.

So our victim was decapitated

some 8 month ago.

And 15 days.

You must not forget, that the body was on

the bottom of the lake for fifteen days.

Before the gases which result from

decomposition brought it to the surface.

Where the first flies were already waiting.

Exactly eight and a half months.

Perhaps less. It was extraordinary warm then.

However, I may assume that the person was

decapitated between the 7th and the 10th.

Is that correct?

Let's think about it.

The first girl disappeard on September 9.

A sixteen-year-old tourist from Denmark.

The body was never found.

Same as with the others.

It is not nice.

Like Greta.

Poor Greta.

She is also on the list.

She is missing but we have

no proof that she is dead.

After finding this what's the use

of hiding from the facts.

There is a killer.

A vicious killer.

We'll get him.

Someone has to catch this monster.

Good night, professor.

Do you know this part of the country?

No, this is my first trip to europe.

People call it the swiss transylvania.


- I don't know. They just do.

So, you are the Corvino girl!

You father is terribly...

- Yes, he is.

I admire him very much.

I thought he might have come with you.

No, he is workin on the Philippins.

He'll be there for almost a year.

He can't even be reached by telephone.

Well in any case.

He has placed you in good hands.

You know I'm sure you are

going to like our school.

To begin with, we all speak english.

And the our academic program

is based on the american one.

Ah... a bee...

Be carefull it may sting you.
