A/N: I've been playing with this idea for awhile, but had no idea if anyone would read an SVU/Sanctuary crossover. I finally decided to write the introductory bit, and if I don't get any interest (hint: reviews!) I will just leave it at this and call it a short one-shot. So please review. Pretty please?

Disclaimer: I own neither Sanctuary nor Law & Order SVU. If I did, there would be a Season Five of Sanctuary and Stabler would still be on SVU. Please don't sue me. I'm broke.

It was the middle of the night, because that was inevitably when the worst of the world came out of hiding. Benson and Stabler ducked the police tape and headed towards the CSU. "What have we got?" Olivia asked, looking at the mangled body laying in the wrong alley in the wrong part of Manhattan.

"No ID on the body, looks to be about 19 or 20. My guess is a working girl that either picked the wrong client or someone picked her. Sliced her to pieces. I've never seen anything like it. There's no apparent evidence that she was raped, but there's so much blood we figured we should call you guys and let you sort it out."

Stabler nodded. "We'll get the body back to the morgue and see what Warner has to say."

A few hours later:

"There isn't an apparent cause of death other than the knife lacerations. I can't determine from the wound patterns which occurred before and which after death. She was either alive for all of them until the kill blow, which I find difficult to imagine, or whoever did this worked fast. Either way is a pretty gruesome way to kill, even for what we usually see. There are no signs of fluids or penetration, however, so I'm not sure this is your case."

Olivia took a defensive poise. "She was a prostitute; that makes her a special victim. If we turn this over to homicide, the case file will get shoved in a drawer and forgotten." Stabler shot her a look that said he didn't quite agree, but knew better than to cross her when her mind was made up.

Before they could even decide to find him, Huang strode into the morgue. Everyone looked up, surprised. He looked sheepish. "I heard rumors, and I needed to see for myself. I think I recognize the pattern." Everyone moved aside for Huang to look at the body. He looked puzzled.

"I know the profile."

"That's good…right?" Stabler asked.

"Not really. Prostitute found in an alley sliced to pieces?"

"Yes." Olivia confirmed.

"Sound familiar to either of you?"

"I'm too tired for guessing games. Just tell us." Stabler snapped. Huang took it in stride.

"Jack the Ripper." Olivia and Elliot exchanged a look, realizing he was right and knowing that this could lead nowhere good.

Meanwhile

"Uh, Doc, you might want to check this out." Henry looked up from his computer as Helen Magnus strode into his lab.

"What is it, Henry?"

"The New York Sanctuary forwarded this police report to me. It's from the Manhattan Special Victims Unit."

"What could it be that they couldn't handle themselves? The New York head knows we are swamped right now cleaning up the mess from the Cabal."

"Don't judge until you hear the details. There's art, too, but I don't think you want to see it."

"Spill it, Henry."

"Someone found a body in an alley. Working girl. Someone sliced her to pieces." Helen started.

"Bloody hell."

"I told you you'd want to check this out."
