Head over to the Polo’s former trading post to get reacquainted with a female you may recognise as being the object of Ezio’s attention back on his arrival in Constantinople – Sofia Sartor. After a discussion of your mutual love of all things hidden and knowledge-related, it’s time to explore the area to find any secrets the Polos may have left behind. Using Eagle Sense, head through to the back of the book store and start examining objects. At the very back you’ll find an oddly patterned area of wall, highlighted in gold by Eagle Sense. Examine this to discover a hidden passage, and end this short Memory.
