On the level night watch I can only find one of two phones. I found the phone in Davidov's office, but I can not find the other phone. Can someone help me?

It depends on the level agent you are on. If agent, then you have to play the level as normal until you get to the pool, you have to cross the pool then go into the courtyard adjacent to it. Here there will be multiple guards and is usually where Gabor is most of the time. on the East side, there is a pair of glass doors, here you go into a room that is the room you were in for the cut scene for the level 'Cold Reception' around here there should be a phone on a stand. Watch out, the stand blends in with the wallpapering. If not, then it should be in the little complex of rooms that are within the mansion. And dont worry about Gabor, there is usually one guard lurking the halls. if that does not help you, Email me
