Thank you

I just watched the Garage Sale mystery "The Novel Murders" and I recognized the plot line immediately. I had recently seen several other Hallmark mystery movies and figured it was the series with Aurora Teagarden because she worked in the library and that all sounded familiar, so I checked out the plot synopsis, and sure enough, that was the one. Even the scenes with the Sherlock Holmes expert were the exact same! The same room, the same actor. Did the just reuse the same scenes and splice the different actresses in as needed?
