In the 1st mission itself, I did this: first strangled the guard, which took from time to time. Further with the help of chloroforms flew the postman and supplier. When entered the territory of the villa, I headed right. Near the garage will stand guard. He will go to you, and when he is close, kill him with a pistol with a silencer. Go through the door, wait, while the fat man goes to cast, and rub it from the barrel with the silencer. Take the keys and climb on the roof. Go on the roof to the Don Office, but not yet enter. Use the card and wait until the Don finds out of the office. When he leaves, go to the other side and hide. When Don returns to the office and stop moving (watching the map), open the door and tiptoe to the mafiosa. Strangle it. Take the keys and go out on the door right. Go straight through the roof almost to the very edge. Turn right and descend down. You will find yourself right next to the staircase leading to the basement. Come in the basement and open the door closed. Look at the camera so that Diana began to justify. Get out of the basement and go to the garage. Hide on the car.
