1:41:00
l think it's
an experimental model...
1:41:02
operated by a crew of midgets.
1:41:04
l think it is powered by
sulfuric acid batteries...
1:41:06
and uses canaries
to detect escaping gas.
1:41:10
Altogether, a unique
contraption.
1:41:13
Not quite that unique.
1:41:15
Right now, four countries
are trying to develop...
1:41:17
what we call a submersible...
1:41:19
but none of them could
solve the critical problem--
1:41:22
how to stay submerged long
enough to make it effective.
1:41:25
What does the good book say?
1:41:28
''And Jonah lived in
the belly of that fish...
1:41:30
''for three days
and three nights.''
1:41:33
That was our goal...
1:41:34
and thanks to
Valladon's air pump...
1:41:36
we got a jump
on the rest of them.
1:41:38
lt's a highly complex
system of filtration...
1:41:39
so we had a series of trials--
1:41:41
And at least one error.
1:41:43
During a test run
in the Moray Firth...
1:41:44
pressure caused
a leak in the hull...
1:41:46
sea water mixed with
the acid in the batteries...
1:41:48
to produce chlorine gas.
1:41:50
Before they could reach
the surface...
1:41:51
Valladon and two of
the crew were dead.
1:41:52
So you had them buried
in unmarked graves...
1:41:54
to preserve your secret.
1:41:56
lt was essential...
1:41:57
to keep the information
from your client!
1:41:59
You went to all those lengths...
1:42:00
to prevent Madame Valladon
from finding her husband?
1:42:03
Your client isn't
Madame Valladon!
1:42:06
lt's the lmperial
German Government.
1:42:09
They were after
the Belgian engineer...
1:42:11
or rather his invention.
1:42:12
They knew he was
employed by us...
1:42:14
but they couldn't
find out where.
1:42:15
So they enlisted the best
brain in England to help them.
1:42:20
You, my dear brother,
1:42:22
have been working for
the Wilhelm Strasse.
1:42:30
And Madame Valladon...
1:42:33
what part did she play
in all of this?
1:42:35
Madame Valladon is dead.
1:42:37
Dead?
1:42:38
The Germans disposed of her
three weeks ago in Brussels.
1:42:45
This is Gabrielle Valladon.
1:42:58
The woman who was
brought to your house...
1:42:59
in the middle of the night...
