Grand Theft Auto IV Walkthrough

Head to the question mark on your map, located on a section of Columbus Avneue in Algonquin that's currently under road construction (necessitating that you drive nearby, get out, and head into the event arrow by walking instead of driving). Once there, the girl you knew as Michelle will come out and smoke a cigarette as she and Niko have an awkward conversation. She then brings you into the skyscraper, where you meet another guy who refuses to give you his name. However, he seems to have Niko by the balls, as it was, and asks him to go take care of a Russian mobster back in Hove Beach (the very first area in the game you travel to). And like that, you're transported back outside and sent on your way.

Boost a car nearby, being careful not to attract any police attention. Then, head back over to the Broker/Dukes island with the help of your vehicle's GPS. The route you take will likely bring you south in Algonquin and then over the Broker Bridge into the borough of Broker, since your destination is right on the other side of the bridge. You're headed for Iroquois Avenue, around your old stomping grounds. Once you arrive at your destination, get out of your car and head up to the door marked by the yellow arrow.

You'll find Oleg's house empty. There seems to be very little here of interest except for a laptop suspiciously sitting on a small table in the living room. Niko will call his mysterious contact and let him know what he's found, and he'll then be ordered to logon and check the guy's e-mail. Approach the laptop, following the same on-screen prompt to logon to this machine as you do at an in-game internet café. Check his e-mail (again, same interface as the internet café computers). You'll find three e-mails, but only the top one is important. Once you read it, Niko will call his contact back automatically and let him know what he finds. Since you now have a new location to head to (Tulsa Street in Hove Beach), you have to head there and eliminate the target.
