We went to Bart's and into the lab. Sherlock explained how the oil will help us find the children.

I went to the loo and when I came back I saw Molly storm out of the lab and push past me.

"Molly, are you-"

"I'm fine." Molly interrupted before leaving.

"Sherlock. What did you say to Molly?" I asked when I got into the lab.

"I-"

"Sherlock?" John asked.

"Hmm?"

"This envelope was in her trunk." John stated, holding up a picture, "There's another one."

"What?" Sherlock asked.

"On our doorstep." John said as he went to his jacket and grabbed something from his pocket.

"Our what?"

"Found it today." John continued and he had an envelope, "Yes, look at that. Exactly the same seal."

We looked at the picture of the envelope from the girl's room and the one that John had. He was right, the seal's were the same. Sherlock looked what was inside the envelope and pulled out bread crumbs.

"Yep. It was there when I got back." John said.

"Little trace of bread crumbs. Hardback copy of fairy tales. Two children led into the forest by a wicked father, follow a little trail of breadcrumbs." Sherlock said.

"Hansel and Gretel." I replied.

"What sort of kidnapper leaves clues?" John questioned.

"The sort that likes to boast, the sort who think it's all a game. He sat in our flat, and he said these exact words to me. All fairy tales need a good old-fashioned villain. Now, the fifth substance it's part of the tale. The witch's house! The glycerin molecule! PGPR! It's used in making chocolate!" Sherlock exclaimed as he walked towards the door and we left for Scotland Yard.


"This FAX arrived an hour ago." Greg said and handed Sherlock a piece of paper.

'Hurry up they're dying!' Was written on there.

"What have you got for us?"

"We'll find a place in the city where all five of these things intersect." Sherlock answered,

"Chalk, asphalt, brick dust, vegetation," Greg read off of what Sherlock wrote down, "What is this, chocolate?"

"Think we're looking for a disused sweet factory." Sherlock said.

"We need to narrow that down. A sweet factory with asphalt?" Greg asked.

"No, no, too general. Need something more specific. Chalk, chalky clay, that's a far thinner band of geology." Sherlock said and he stopped moving, only his eyes looked around quickly.

"Brick dust."

"Building site, bricks from the 1950s."

"There's thousands of building sites in London." Greg said.

"I've got people out looking." Sherlock told him.

"So have I."

"Homeless network." Sherlock began pacing, "Faster than the police, far more relaxed about taking bribes."

Sherlock's phone rang and he smirked at Greg before his eyes moved from his phone screen and to the space in front of him. He was doing that map thing again, most likely.

"Amelia."

Sherlock held his phone out towards me and showed me a picture of a purple flower,

"Rhododendron Ponticum. Matches." He dropped his arm, "Addlestone."

"What?" Greg asked.

"There's a mile of disused factories between the river and the park. It matches everything." Sherlock said and we quickly left.

Once the car parked outside the factory, we all rushed inside. We were given small torches and we all looked throughout the factory. I split away from Sherlock and John, hoping to find the kids.

I walked throughout the building, and behind me I heard heavy breathing. I turned around and saw two small bodies. The girl turned around and looked at me.

"Claudette? Max?" I asked and the girl nodded.

"Over here!" I yelled, "I found them!"

I crouched beside them, "Everything's going to be okay. You're going to be just fine. Don't worry."
