Playing With / The Dog Was the Mastermind

Basic Trope: When the least likely character to be the Big Bad or The Man Behind the Man, is.
  • Straight: Detective Bob finds out that Carl the car dealership owner, who sold him a car earlier, is the Mafia boss he had been tracking.
  • Exaggerated: Detective Bob, after investigating several crime lords and shady politicians, find out that his wife Alice's dog, Fido, is the Mafia boss.
  • Downplayed: Detective Bob discovers that Alice herself was behind the crime he's investigating. This shocks him (and the audience) at first, but since Alice was a Jerkass in the first place, it all makes sense.
  • Justified: Carl takes on a normal job, which has no connection to crime, so he would never be suspected.
  • Inverted:
  • Subverted: Carl the car dealership owner is a former mafia boss under the Witness Protection Program.
  • Double Subverted:
    • ...Who is actually a detective, investigating the true Man Behind the Man.
    • Carl supposedly proves his innocence to Bob, then it is revealed that he had been pulling the strings all along.
  • Parodied: Fido enjoys seeing Detective Bob not suspecting him, just because he is a dog. But it's just a ruse so he could take over the world once all of the suspects (who are his greatest enemies) are arrested.
  • Zig Zagged: The man did it, but wait, he was really behind The Dragon, but The Dragon was really the man behind the mastermind...
  • Averted: The Man Behind the Man is just one of the suspects or some other likely person, not the least likely person.
  • Enforced: "Hey, how about we make the criminals Carl, the car dealership owner? The readers won't ever find out."
  • Lampshaded: "Carl, you're the Mafia boss? How sneaky of you for adopting that ruse,"
  • Invoked: Carl becomes a car dealership owner so he could become a Mafia boss without anybody knowing.
  • Exploited: Since Fido knows that no one will ever suspect him as being a serial killer, he becomes one and frame people left and right, warding detectives off the right path.
  • Defied: Detective Bob refuses to believe that the least likely suspect is the criminal, and Carl doesn't adopt such a silly cover job.
  • Discussed: "Hey, it's probably the dog who did it all, because he knew we wouldn't suspect him." "The dog? Seriously? You've been reading too many cheap mystery thrillers lately." Cut to a scene where Fido makes a Sarcastic Confession.
  • Conversed: "This such a predictable movie... Wait a minute! What just happened? Carl was behind it all? Why? It doesn't make any sense!"
  • Deconstructed: Fido really was the mastermind, but because he didn't plan ahead, Fido panics and reveals himself out of guilt.
  • Reconstructed: But since Detective Bob thinks that Fido is innocent (as he's just a dog), Fido gets to continue his Evil Plan scot-free.
  • Played For Laughs: It's really freaking obvious that Carl is a Mafia boss putting up a ruse as a car dealership owner, but Hilarity Ensues when Bob outright refuses to acknowledge that, even when the evidence is right in front of him!
  • Played For Drama: Fido successfully pulls off his Evil Plan, but he wasn't Crazy-Prepared enough when he's revealed to be the mastermind. His crimes gets him 260 different life sentences.

Wait, the link called, The Dog Is the Mastermind is the mastermind!
