Arturo Genosa is a human male and erotic film producer. He first appears in Blood Rites.
Arturo Genosa is the owner of a fledgeling porn production company. At the behest of Thomas Raith, he hires Harry Dresden, believing that a Strega is behind a vicious curse called the Malocchio, probably aimed at him, but it's causing people around die in very strange ways. Dresden's hired to find and stop the person(s) behind the entropy curse, and to protect his people.
Joan Dallas, Arturo's producer, describes him as someone who live on the outside of his skin: he's impulsive, more passionate than he can afford to be and he'll fall in love at the drop of a hat. He makes up for it by caring about people.
Dresden describes him as a decent guy. He takes measure of responsibility, challenges the status quo even if it hurts his profit. He's applying some measure of integrity to what he does.
He seems to be something of a revolutionary in the porn industry and interviewed in a lot of big name media like Times. He casts a lot of varrying age ranges, avoids genital close-ups, thinks people should enjoy themselves without meeting some insane standard—he treats it as natural.
He's a dual citizen of the US and Greece, and he's the last son of a big-money family that fell on hard times. He left Greece to avoid his family's debts. He started making and directing sex films, something that made him very wealthy. However, he has all of it invested in his new studio and pays alimony to three ex-wives.
In the series
In Blood Rites, Thomas Raith does favors for Harry Dresden in order to get Dresden to do a favor him—help a friend of his, Arturo Genosa whose people are dying around him in odd circumstances. Thomas take Dresden to meet Arturo at a cast and crew party being held at Madge Shelly's apartment, Arturo's first ex-wife. Arturo talks with Dresden about the strega and the malocchio and hires Dresden to protect his employees and find the person(s) behind the curse. He doesn't think any of his three ex-wives are involved.
He only has thirty-six hours to get his second film done or he'll lose the studio.
