I loved the use of WW II spy history in Istanbul. The writing was magnificient and the diverse cast of NPCs diverting to my players and to me as a Keeper. The maps gave enough detail to evoke the city but not confuse with the obvious amount of detail that exists in reality. Istanbul was neutral in WW II but not on the sidelines when it came to spycraft and intrigue. This book uses both!
