Right before the scene where Roe is at the Library reading Sally's news article, the camera pans up past a row of books. The books happen to be the Sookie Stackhouse novels, another set of novels author Charlaine Harris writes.
Real Murders is actually the first book in the book series, and A Bone to Pick is the second book in the book series, yet they chose to make the 2nd book the first movie, and the 1st book the second movie.
Based on the Aurora Teagarden novel by Charlaine Harris.
When the murder chart is rolled up, it was rolled from both ends making two tubular rolls, and is carried away like that. When it is pulled out of the car, it is just one large roll. Since they were in a hurry, it is more likely that it would not have been rerolled into a single tube.
The first of two appearances of the character Robin Daniels in the movie series. He returns in the seventh movie, Last Scene Alive.
