Crossed Up - S3-E13
Continuity mistake: When the crime is solved Jessica shows her emergency calling button. The way she holds it changes between shots.
Crossed Up - S3-E13

Night of the Headless Horseman - S3-E11
Continuity mistake: In the car, when Jessica is told that she has to act like Dorian's mother she covers her face with both hands. A shot later there's just one hand on her face.
The Bottom Line Is Murder - S3-E15
Continuity mistake: When the cop picks up the dirty ashtray he blows the ash away. In the close-up the ashtray is spotless as if it had been wiped with a cloth or if it were brand-new. First of all, no ash blew away, and second of all, a mere puff couldn't have cleaned it the way it looks.
Chosen answer: This is the very reason my brother and I used to jokingly call the show, "Murder, She Caused." It's amazing she was ever on anyone's guest list for a party, given the likelihood someone would end up deceased. As to your question, most of the time, Jessica Fletcher would have had an air-tight alibi, as she was in a room full of people, or her whereabouts were accounted for when a murder occurred elsewhere. It also seems to me that there were episodes where she, purely with respect to opportunity, could have been a suspect. I believe she even acknowledged that as a logical possibility from time to time, even though she knew, of course, she was not the killer. However, the investigation would obviously rule out the possibility of her involvement, eventually.
