Who doesn't love a good mystery? From Agatha Christie to Scooby Doo, a solid mystery can hook audiences, bring in viewers and make for some truly incredible works of fiction.
The WWE aren't afraid to have a good mystery for their audience to solve. For example, when Stone Cold was run-over during the height of the Attitude Era.
Being mowed down at the 1999 Survivor Series, Austin stopped wrestling for just under a year, as he tried to find out who would attempt to end his career, and cripple his life.

New Champs in WWE! More RIGHT HERE
Eventually, it was revealed to be Rikishi, who claimed to have done the deed "for The Rock", but later revealed to be the hitman for the Game, Triple H.
But unfortunately, some mysteries in WWE have never been solved, and with the company moving forward, will likely never be revealed.
Here are 5 unsolved mysteries in the WWE.
#5 Who raised the briefcase? (King of the Ring 1999)
Before being run down at the Survivor Series, Stone Cold had an interesting 1999, at one point becoming the CEO of the World Wrestling Federation.
Horrified at the notion of his former nemesis as the boss, Vince McMahon demanded that the Rattlesnake be removed from his post, though his request fell on deaf ears.
Eventually, the two squared off, with Vince, alongside son Shane, facing Austin in a Handicap ladder match, for full control of the company.
With company documents hanging above the ring, The Rattlesnake seemingly had things won, climbing the ladder to vanquish his foe once and for all.
However, as he reached for the briefcase, it would move upwards, out of reach, only coming down when Austin was on the mat.
Vince and Shane would go on to win the match, and despite theories from fans, the third-man behind this was never revealed.
#4 Who attacked Hideo Itami?
When Hideo Itami joined NXT, he was one of Triple H's biggest signings. An established star as KENTA, Itami was seemingly bound for an NXT Title shot.
At NXT TakeOver: Unstoppable in 2015, Itami was set to face Tyler Breeze and Finn Balor for a shot at the gold, but was found attacked backstage.
In reality, Itami was injured and unable to compete, but the backstage assault led to many theories as to who would attack the Japanese star?
Perhaps it was then NXT Champion Kevin Owens, who saw Itami as the most real threat to his title?
Or maybe Baron Corbin, who at the time had made his disdain for smaller Superstars clear.
Perhaps even, it was Samoa Joe, who just so happened to debut the same night.
In the end, we never got an answer, Itami returned several months later to no fanfare and no conclusion. Itami would never hold the title, and sadly is seen as one of NXT's biggest flops.
#3 Who was cranky Vince?
Perhaps the most unknown mystery on this list, but the tale of Cranky Vince is one that needs to be seen to be believed.
On Twitter, there are plenty of WWE parody accounts, from someone posing as a tragically honest WWE Creative, to Scottish versions of The Undertaker and Triple H.
But Cranky Vince was something entirely different, as it was reportedly things the boss had said, or at least said in other words, during real meetings backstage.
Instantly, suspicion arose as who could be the leaker, with John 'Bradshaw' Layfield becoming the prime suspect, after he and Cranky Vince posting the exact same tweet, only for CV to delete the tweets moments later.
Despite being the only lead and de facto prime suspect, the former WWE Champion denied it was him, and the account was later deleted when WWE cracked down on parody accounts.
#2 Where is Jericho's end of the world?
When Chris Jericho returned to WWE in January 2012, it was a very different Y2J to the one we had seen before.
Despite Jericho being famous for his promos, he refused to utter a word for several weeks, a divisive decision.
Whilst some fans grew irritated at Jericho's odd behavior, many (myself included) loved this new, weird side of Jericho, who didn't rest on his laurels.
When he did speak, Y2J promised that the end of the world was coming and that he would watch as it happened.
Whilst the first ever Undisputed Champion was cagey on details, he promised something was coming, much greater than himself.
Now, nearly seven years later, we are still waiting for that something.
Being the last eliminated star in the 2012 Royal Rumble, Jericho quietly stopped talking about the end of the world, instead focusing on CM Punk's WWE Championship.
#1 Who was behind GTV?
During the Attitude Era, something took the WWF by storm. A series of grainy, monochromatic videos, showing Superstars backstage, revealing hidden secrets that wrestlers wanted to keep secret.
Called GTV, the videos led to a sense of paranoia amongst the Superstars, with everyone trying to figure out who was behind it.
At one point it was believed the G stood for Goldust, who at this point in his career, was a known film love, so perhaps he could be a Peeping Tom also?
Halfway during the storyline, however, Goldust was released by the company, and wouldn't be seen again until 2002, and GTV was quietly fizzled out.
Whilst the abrupt end of the product further implicates the Bizarre One, no actual conclusion was given on WWF TV, and now, nearly 20 years after it began, GTV remains one of the biggest mysteries in all of WWE history.
