Spellman Files

The Spellman Files is a series of books by Lisa Lutz, which features a family of private investigators in San Francisco. They're all very obsessed with their work. Wackiness Ensues on a regular basis.

The books so far are:
 * The Spellman Files
 * Curse of the Spellmans
 * Revenge of the Spellmans
 * The Spellmans Strike Again
 * Trail of the Spellmans

The main characters are:
 * Isabel Spellman: our narrator, who's been a PI since age 12 and has never done another job. A former juvenile delinquent, she's only somewhat reformed in her behavior, and is an obsessive investigator. Kind of a Heroic Sociopath in her own way. Either lives with a family member, or in some divey place, or wanders around homeless. Has a dicey dating history as well. The series seems to be a Coming of Age Story for her, as she slowly starts growing up at around age 30.
 * Albert and Olivia Spellman: the parents/owners of Spellman Investigations. Brought their children up to be PI's and to spy on each other.
 * David Spellman: Oldest and only son of the Spellmans, the "good kid." Got out of the family business and became a "straight" lawyer. Then he starts to break down...
 * Rae Spellman: The "surprise" child, now a teenager. A master manipulator even in her teens, she's an entirely different form of trouble than Isabel. Has adopted Henry as her "best friend", which her parents allow because he's the only good influence on her (as well as that's going to work). Smarter than she lets on.
 * Ray Spellman: A former cop who's prone to "Lost Weekends" where he goes on benders. Has an...interesting...relationship with his namesake.
 * Inspector Henry Stone: unfortunately, he meets Rae when she fakes her own disappeareance. She promptly adopts him and won't leave him alone since, much to his dismay. Isabel later develops an unrequited crush on him.
 * Petra: Isabel's best friend, who marries and later divorces David. She's a lot wilder than he is.
 * Daniel Castillo: Isabel's ninth ex-boyfriend, who remains in their lives even after she traumatizes him by dating him.
 * Maggie Mason: a nice lawyer that Henry dates, and that the Spellmans like despite themselves.
 * Morty Schilling: Isabel's eightysomething lawyer friend.
 * Milo: Owner of Isabel's favorite bar, The Philosopher's Club.
 * Connor: bartender at The Philosopher's Club, Isabel later dates him.
 * Fred Finkel: Rae's boyfriend later on.
 * Demetrius Merriweather: a TV thief who was wrongly convicted of murder, Isabel and Maggie worked to free him.
