Leo Kowalski: You sure are persistent.
Jessica Fletcher: Well, I've been described in less flattering terms, believe me.
Sheriff Tupper (walking into Dr. Hazlitt's office): Listen, Seth, if you can tear yourself loose from killing off your patients ... you got to get over to Main Street quick! And bring your bag!
In an interview with the Archive of American Television in 2000, Tom Bosley recalled an incident from the filming of this episode. Arriving on the location for the excavation scene, the crew found four men with shotguns who would not let them film on their property. The reason was because they were growing marijuana, so the crew dug the excavation pit on a park nearby. Universal Studios later built a parking lot over the hole as payment.
