Assassin's Creed Revelations Walkthrough Part 38 – The Spy Who Shunned Me

Full Synchronization requires that you do not kill anyone.

Head for the memory marker that is on the opposite end of the cavern. You will learn that Dilara has been captured and taken to the prison. All of the prison area is restricted so wait until there are no patrols in the area then make a dash up the stairs.

Once up there you are treated to a cutscene where you learn the person with the Prison key is in the market. Head down a landing and to the right. There is a handy zipline here giving you quick access out of the Prison area. From there head on back to the market area. Make for the upper left part of the marked area. You will find the guard watching a fight. He is in the front row, second from the left. Pickpocket him and get away quickly.

When you return to the steps of the prison area there will be a group of guards to deal with. If you are after Full Synchronization then you will want to head to the west of them and use a nearby rooftop to scale upwards. Once inside head for the marker. It is surprisingly empty. Head to the back to free your source.
