In a recent 'Reaper' episode, Bert "Sock" Wysocki used 'Murder, She Wrote' as his alibi. For the audience viewing at home, O'Bviously it was supposed to be a reference to the TV show starring Angela Lansbury.
But that doesn't work for Toobworld. Even though the two shows are wildly different in tone and subject matter, 'Murder, She Wrote' and 'Reaper' share the same TV world.
There's an easy splainin, however. (I wish I had an Easy Button for splainins!)
For Sock, "Murder, She Wrote" is not a TV show. It's a biography of Jessica Fletcher (a member of the TV Crossover Hall of Fame, by the way). Mrs. Fletcher has been around long enough as a best-selling author, and one who solved almost 200 murders at that, to warrant such scrutiny. (Hopefully it hasn't been in her memory!)
And that closes the book on that Zonk!
