I read about this movie on IMBd when it appeared in our TV listings and subsequently recorded it. Kathryn, my wife, and I watched it this evening. It turned out to be a compelling who-dun-it that not only kept us guessing but, though each of us had picked a different killer, we were both wrong! We watch a lot of mysteries and I can frequently figure out the killer quite early on. Is that because I am great detective? Hardly. It is because I have caught on to the often formulaic writing even in the best of TV series and movies; thus when I say that neither of us twigged to the killer in Best-Selling Murder (aka Serialized) it is high praise indeed. The only problem I had with this imaginative show was the resemblance of the star to the star of Supergirl. Well worth a viewing.
