Raymond Kulinsky

Raymond is the killman here; he's set up a sniper's roost above one of the three clubs in the area, and isn't going to budge until he gets word to fire. Unfortunately, his position is generally determined at random, so far as we can tell, but he rarely chooses to take up a spot above the blues club to the south; we've most often seen him above the salsa club in the eastern part of the map.

Determining Kulinsky's location will require you to either eavesdrop on Purayah's conversations from the old bookstore or grab a walkie-talkie from the body of Purayah or Mason. The walkie-talkie is your best bet, as that'll pin down both Mason and Kulinsky.

Up Close And Personal

When you've determined Kulinsky's hideout, there are two methods to take him down. The more complicated method will be to infiltrate the club beneath him and make your way up to his roost. You can't just walk into a club, though, as they all have uniform restrictions which are difficult to get around. You can access any of the clubs, however, by obtaining a waiter's uniform. Most of the alleyways behind the clubs will have waiters stalking around on smoke breaks periodically, but the easiest way to obtain a uniform is to head into the alleyway behind the hotel where you start the level. Poking around will reveal a lattice near a plant; climb up this, and you should find an open doorway where a waiter is sleeping one off. Sneak in, grab his uniform, and you're set.

You'll need to enter the club with your uniform on, head into the rear areas, then find the room where Kulinsky is hiding before sneaking up on him and killing him. This is usually on the second or third floor of the building, and he does pace around, so be sure not to enter the room when he's looking in your direction, or he'll generally just start firing away, regardless of your outfit, although he may give you some leeway if you're wearing a guard chicken outfit.

Countersnipe

Secondly, you can attempt to countersnipe Kulinsky by finding a position from which you can see into the window of his room. If you head to the eastern set of alleyways, you can find two such positions. The blue door in the southeastern corner of the alley will lead you to an apartment from which you can snipe into the room above the salsa bar, while the waterpipe atop the raised platform will come out in a position that'll let you snipe away at Kulinsky if he happens to be in the rock bar. The blues bar is the most difficult to hit, since you'll have to snipe from the hotel room that the guard chicken has rented, and he won't give it up without a fight.

Anyway, when you have Kulinsky's position nailed down, take up a position in the countersnipe spot, get your sniper rifle out, and wait for him to walk to the window before nailing him.

Angelina Mason

Angelina is the most difficult of the three targets to take down, since she roams all around the map, making periodic stops in the alleys around the map. Once you get her position on your map after picking up a walkie-talkie, she's easier to track and kill; just get in front of her, wait in one of the alleys that she's approaching, and perform a stealth kill as best you can. If you do go this route, be sure to save her for last, as that'll give you a better chance of exiting the level without having her body be discovered.

If only she were a real roadrunner, this wouldn’t faze her at all.

Alternately, you can try to drop a piano on her head. In the alleyway to the south of Purayah's little hovel, there's a piano suspended from a rope. You'll have to climb up via some nearby trashcans and do a little platforming to reach the winch, but doing so will let you plant a bomb on it. At that point, all you have to do is wait for her to make her rounds back to this alleyway, then detonate the bomb to get her with one suspicious-looking accident. Still, it's an accident nonetheless...

Beating The Street

When all three of your targets are dead, you're considered to have automatically "protected the secretary", so that objective is wiped off the list and you can escape. Note that, although the intelligence indicates that Kulinsky and Mason will go crazy somehow if either of them are killed, this doesn't seem to actually happen, unless perhaps we just didn't wait long enough between killing them. Also note that, again, making it to the escape point with the briefcase of diamonds will net you 100,000 extra dollars. You won't be able to escape with both the diamonds and your sniper rifle, but paying for the rifle retrieval will only set you back $5,000, so it's well worth the effort to get the diamonds instead.
