Prologue: When we last left Sly Cooper, he had stopped being a thief and started his office work. Then he framed his former friends Bentley and Murray because they went on his chat rooms. he then accidentilly set them all loose, resulting in Sly getting fired. In an attempt to get his job back, Sly tried to rob a bank by using a rock like a grappling hook, except he got a concussion and wound up in the mental asylum.If you read chapters 1-9, you have missed the alternate ending, chapter Z For more information, read SLY 4: THE FALL OF THE COOPER NAME.

Chapter 1: The Asylum

Sly walked up to the treasure chest. All those trials and traps led to this one moment. Finally he would be richer than everyone with the honor of 10 TRILLION Thieves. He would be in the news for the rest of his life. With the power of the chest, he could rule the world. It was time. Sly opened the chest. A skull rose out. Sly immedietly grabbed it. The skull unleashed its power over Sly. He fell over, dead.

"AAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHH!" Sly screamed as he woke up. "I DON'T WANT TO DIE!"

The door of the cushioned room swung open to reveal 2 goons wearing medical clothes and carrying syringes.

"It's sleepy time." one of the goons said as he injected Sly with the Institute's patented knock-out syrum.

"It's, NOT...sleepy...time." Sly said as he drifted to sleep.

62 miles away, the police department was in extreme debt. It turns out, that the interpol website was the only way the police department in town was making any money (don't ask). Now they needed someone with computer skills, but couldn't be a turtle because Lieutennant Brown was afraid of them.They needed Sly back.

"We don't need Cooper back. He was a menace and an evil person and a spaz." Lieutennant Brown stated.

"But-" Steve began.

"Stop! If anyone says anything about this anymore, they will be fired on the spot." Lietennant Brown finished the subject.

Sly paced back and forth in his cell. He had to get out soon. He was going insane. Then the familliar doors of the room opened to reveal the famlliar goons. They opened their mouths to say something, but they turned into a swirl of colors and shapes. Sly woke up again. The syrum was messing with Sly's brain. He couldn't tell if he was dreaming or awake. He cowered in a corner of the room. Then he woke up.

"WHY WHY WHY WHY WHY WHY WHY WHY WHY WHY WHY WHY!" Sly sobbed.

"I'll explain everything." The old man said.

Will the old man explain everything? Why does the syrum make Sly go insane? Why does Steve want Sly back so badly? WHY WHY WHY WHY WHY WHY WHY WHY WHY WHY!
