Idea for a Novel

An undercover agent sits recuperating in a Sarıyer home, observing the goings on in an ordinary Turkish family, with all its talk of relatives and marriages and newly bought houses. (and even TV series) He is the estranged friend of the daughter of the house, who seems to be settling in nicely after her years abroad. After the observations of the spy (Russia? Middleeast?), through flashbacks we get the story of the daughter of the house, who's recently (?) married and lost her lover, all unbeknownst to her family.
