Was it Marta's fault? *BIG SPOILER*

It's possible. Remember when his wife kept interrupting the dinner with her tosses, the man stared at her in a funny way, as if he knew something. Who is this man anyway?

It's very simple.. The woman was basically a woman with clout, with a gang that resembles a mafia, when she didn't get what she wanted, she exacted her revenge. Nothing to do with the other parts of the story.

Although yes being gay is still a big deal in Turkey, NO they do not kill people for being gay! Actually there are a lot of places for homosexual people to go to and in Istanbul all they would get is a weird stare. Yes they might be disowned by their parents or ridiculed by their surroundings (which happens all over the world unfortunately) but they do not get stabbed at their door way because they are gay or because they cheat on their significant others.

Zozo, the real estate guy, told Francesco the people who wanted to buy his property were "dangerous people". I haven't seen the movie in a while, but I clearly recall a model of some kind of modern building which implied they were developers.

It seemed to me they wanted not only Francesco's building, but also the surrounding buildings in that area so they could knock them down and set up profit-making businesses. The neighbors were afraid if the Italian sold the bldg with the hamam to the developers, it would be the beginning of the end of the neighborhood.

Francesco was shedding his old life of stress and unhappiness, embraced by the warm Turkish family, and even opened a side of himself he may not have known was there when he started the affair with the handsome son. He opened up his creative side as a former designer when he decided to restore the hamam. He was changing, and he felt good for the first time in years. When he decided to keep the building and enraged the greedy gangsters, I doubt he had any idea what could happen. It's such a sad ending, because I Francesco seemed clueless as to what was coming his way.

The gangsters killed Francesco as a warning to all the homeowners in the area not to stand in their way, or more people would suffer severe consequences.

His death had nothing to do with his affair with a man.

^ yeah my take away was it was a hit from the business woman that he turned down last minute instead of selling to, and subsequently stopped everyone else from selling to. Remember how the dude came to Francesco screaming about how she was very dangerous?
