Use copy/paste. I cant report that he is in No. 19 Leningradsky Prospekt, looks like Im missing something but I dont know what.

Look at Pearson's file in the CIA Datalink
files to find Rajiv Jalabad's address

NVM! Didnt read that line.

If anyone get stuck:

1-Click CIA on the DATA LINK of your PDA

2-Click 201 FILES

3-Click on MOSCOW STATION CHIEF FOSTER,MAX

4-Click on SUPPORT PERSONNEL

5-Click on Pearson, Owen A.

6-Click on Operations Log

7-Click on CLICK HERE for Access to Address.

A mess. Maybe there's an easy way to get there or to guess the address but I do not know.
