Confess, Fletch is being released this week.  

The film is based on the novel of the same name by mystery writer Gregory McDonald. 

It will feature Jon Hamm in the role made famous by Chevy Chase in a 1985 film (Fletch) and its less-than-beloved 1989 sequel.

McDonald's Fletch is an investigative journalist who files stories on two separate-but-interrelated scandals, then flees with a briefcase full of money. 

In his second novel, published two years later, he is out of the journalism game and living on his ill-gotten fortune. 

He's engaged to a beautiful young woman whose father is an Italian count who has fallen on hard times. 

His art collection, which represents the bulk of his assets have been stolen. 

In the book, Fletch falls in love with the would-be widow of Alan Stanwyk, a supposed cancer patient who wants to end his suffering. 

When it turns out he's actually being faking his own death, he flees the country with her and an entire briefcase full of money. 

In the movie version, he's hunted by drug dealers who want to murder him and fake his death.

In the book, Fletch is engaged to the daughter of an Italian aristocrat, whose art is stolen and who is then kidnapped. 

In the movie, much less emphasis is placed on the art being all that the family has to their name. 

The kidnappers are specifically asking for one of Menti's (the count's) paintings, so his fortune doesn't come into play.
