I'd like to throw out an alert to all newbies:
I just unlocked (as I thought) a favour in New York (the Priest told me the Butcher had work for me), but since I was planning to go to Delhi I figured logically that I'd have a favour available there too since after all I had solved my cases like a good boy to get my favour. So I traveled to Delhi. No favour. "Damn" I thought. "I must go back to New York to solve the favour there obviously". So I went back to NY. No favour. Waste of 8000 (so don't you whine about the 500 Larry wants for showing you Big Lucy's) and eight turns.
