:58:02
to keep the British occupied
searching for buried treasure.
:58:06
The treasure is a myth.
:58:09
I refuse to believe that.
:58:16
Well, you can believe what you want.
You're a grown person. What am I doing?
:58:21
Do what you want, Ben.
Do what you want.
:58:25
He's probably right. You don't even know
if there is another clue.
:58:32
Well, I can think of a way where we could
find out. And we can find out right now.
:58:53
Looks like animal skin.
:58:56
- How old is it?
- At least 200 years.
:58:59
- Really? You sure?
- Pretty darn.
:59:03
Now if this thing's in invisible ink,
how do we look at it?
:59:05
Throw it in the oven.
:59:07
- No.
- Uh-uh.
:59:08
Ferrous sulphate inks
can only be brought out with heat.
:59:11
- Yes, but this...
- It's very old.
:59:14
This is very old, and we can't
risk compromising the map.
:59:19
You need a reagent.
:59:21
Dad, it's really late.
Why don't you get some rest?
:59:23
I'm fine.
:59:26
Lemons.
:59:34
- You can't do that.
- But it has to be done.
:59:36
Then someone who is trained to handle
antique documents is gonna do it.
:59:41
OK.
:59:45
OK.
:59:48
Now, if there is a secret message,
:59:51
it'll probably be marked by a symbol
in the upper right-hand corner.
:59:56
That's right.
