i really dont remember (i havent played that level in like 6 mounths) but i just ran down killed the son and ran up in the mansion and killed the old fart

First you silent kill the guard on the far right outside the property and take his
uniform. toss him over the edge. Then walk all the way around the other side of the
property and silent kill the other guard. On that same side, walk down the path towards
the dock. silent kill three men below for an easy exit. Go back up. Go all the way around
to where you killed the first guard and go through that side door. climb the boxes into
the backyard of the building. silent kill the 2 guards there and take one of their
uniforms. go up the pole up to the balcony and walk right by all of security with ur
uniform. wait till old guy comes out of his room and wait in opposite room till he comes
back. he should be playing the violin by the window. strangle him and toss him over the
balcony. their should be an exit on the room on the right through the window. walk all the
way to the front. go through the door straight ahead and wait for him downstairs. silent
kill him and walk right out. walk out of the property back to the far left of the property
back down to the path and enter the plane. all done...simple.

its easy i done it i tell you when i go back on it .

okay when you start go all the way left there should be a guard at the end walking. take
out your gun and kill him no one hears the gunfire. suit up as him you know when your
going left there should be a box or somthing climb over the wall go a little bit left and
go until you see a door no ones guarding it. climb the pipe next to it but dont go to far
out on the roof or they will see you and shoot. go right you will see a window wait for a
guy in a white suit he will start playing the cello.poision him and you killed your first
guy sneak out the window and go straight and jump off the roof.now go back where u started
if your still dressed as a guard go through the door to the village go into the place that
looks like a church go down the stairs and find a guy in a pink shirt. follow him until
he goes into a space by the stairs kill him and leave the place go to the place where you
start go left again go straight up. u should see an area with an open part in the fence go
all the way down go by the plane and escape. bye. ps this was one the hardest levels 4 me
when i didnt know how to do it.
