It had been two months since the court case with Moriarty and we had heard nothing from him.

I think that's a good thing but anything can happen in this story!

I came down stairs then had my jacket thrown at me by Dad.

"Come on Brooke, the game is on!" He told me and dragged me down the stairs.

Most parents would say good morning but hey no bodies perfect!

Dad filled me in on the way; A British Ambassador's children had been reported missing and he had asked for Dad and I to investigate it!

Lestrade pulled up outside a boarding school and we all exited the car and walked towards an old lady who was wearing a shock blanket.

"Miss Mackenzie, you're in charge of pupil welfare," Dad started.

Miss Mackenzie just stood their and nodded sadly.

"Yet you left this place wide open last night! What are you, an idiot, a drunk or a criminal?" Dad shouted and pulled the blanket off her shoulders. "Now tell me!"

WOW!

"All the doors and windows were properly bolted," The woman began shakily. "No one, not even me, went into their room last night! You have to believe me."

"I do, I just needed you to speak quickly," Dad told her and walked into the building.

"And Miss Mackenzie will now need to breathe into a bag," I told the medic and ran after Dad.

Lestrade led us to the girl's room first. Dad began to look around the room for any clues.

"Any other kids on this floor?" I asked.

"No, just those two," Lestrade told me. "The intruder must have found a place to hide."

I looked under a few beds then opened a chest. There was some sort of package inside it, I pulled it out and opened it, a book, a Grimm's fairy tales book. Dad came over to me looked at the book, he flicked through some of the pages then put it back in the chest.

"Show us where the boy slept," Dad ordered. Lestrade led us straight there.

This room was much smaller. Dad immediately pointed out the boy's bed and began to look around the room.

"So the boy sleeps here every night. Gazing at the only light source, outside the corridor," Dad told us.

"He always looks at it, he can make out shapes and is able to recognize them," I caught on.

"Okay, so?" Lestrade asked.

"Someone obviously came to the door, that someone being the intruder," I told him. Dad nodded and urged me to go on. "Maybe he saw the outline of a gun?" I suggested.

"Good, so in those precious few seconds, how would he use them if not to cry out?" Dad asked us. "This boy, this particular little boy who reads all those spy books." Dad then began to smell the air he walked over to the bed and an empty bottle Linseed oil. "GET ANDERSON!"

Before we all knew it, the windows were covered and we used Black light to see some writing on the wall 'Help us'. I looked at the floor and noticed some blue foot prints.

"Not much use," Anderson told us.

"Er Anderson, look at the floor," I told him.

Everyone looked at the floor then followed them.

"The boy was made to walk ahead of him," Dad began and to follow the trail out the door.

"On tip toe?" John asked.

"Indicates anxiety. Gun held to his head, the girl was pulled up beside him, dragged sideways. He had his left arm cradled around her neck," Dad told us then the trail stopped.

"That's the end of it. We don't know where they went from here. Tell us nothing after all," Anderson told us.

"Your right Anderson," Dad agreed. WHAT? "Except his shoe size, his height, his gait, his walking pace," Dad told us the ripped the black sheet off the window. He dropped to the floor and began to scrap up samples off the floor.

"Having fun?" John asked.

"Starting to," Dad told him.

"Yeah, that's fine but try not to look so pleased about it," I mumbled and John nodded in agreement.

Dad, John and I got a cab and headed to St Barts. We talked about how the intruder managed to get inside: End of term, parents and carers would have been walking around collecting the children and the intruder walked in the building unseen then found the perfect hiding place. Simple!

We went into Barts and walked towards the lab and on our way we bumped into Molly!

"Molly!" Dad and I greeted.

"Oh, Hello I was just going out," she told us.

"No, you're not," Dad said and turned her round.

"I've got a lunch date," she tried to protest.

"You're having lunch with me," Dad told her and pulled out a load of bags of crisps out of his pocket. Molly would never resist a lunch date with Dad.

"We need your help," I told her. "It's one of your old boyfriends."

"He's been a bit naughty," John added.

"It's Moriarty," Dad told her.

"Jim actually wasn't my boyfriend. We went out three times, I ended it," Molly told us.

"Yes and then he stole the crown jewels, broke into the bank of England and organized a prison break at Pentonville," Dad told her.

"You basically broke up with a psychopath," I told her and followed Dad into the Lab.

I grabbed the tennis ball off the side and began to bounce it off the wall. I was never good at lab work so I just stay out of the way and amuse myself.

Every so often Dad would say what he found in the samples.

"Hey guys," John called Dad and I over and showed us the photo's we took of the children's rooms. "This envelop was in the trunk. There's another one, it was on our doorstep, found it today," John told us as he showed us the envelop both seals were exactly the same!

Dad opened the envelop. "Bread crumbs," He muttered. "A little trace of bread crumbs, a hard back copy of fairy tales. Two children led into a forest by a wicked father, follow a little trail of bread crumbs."

I know that story. "It's 'Hansel and Gretel'," I told them.

"The fifth substance is PGPR!" Dad told us and ran out of the lab.

"What?" John asked as we trailed behind.

"It's made in chocolate," I told him.

The three of us got a cab and drove to Scotland Yard.

Once at the Yard Lestrade waved a piece of paper at us. "This was faxed to us over an hour ago," He told us. It read 'Hurry up they're dying.'

"We need to find a place in the city where all five of these thing's intersect," Dad told him and handed the list of substances he found in the samples.

"Chalk, asphalt, brick dust, vegetation... what the hell is this, chocolate?" Lestrade asked.

"We're looking for a disused sweet factory," Dad told them.

"We need to narrow that down," Lestrade told everyone. "A sweet factory with asphalt?"

Everyone began trying to narrow it down. Lestrade had the officers of Scotland yard and Dad had his Homeless network.

Dad got a text from one of his people. We had a location! "Addlestone! There's a mile of disused factories between the river and park! It matches everything!"

We all quickly got into police cars and drove to the factory. We got out our flash lights and began to search the building. I went off with Dad, the place was dark, cold and damp.

"Look," Dad said and shined his light at some sweet wrappers and a candle. Dad touched the candle. "There still here!" He inspected the wrappers then licked it. "Mercury."

"Can't that kill them?" I asked in horror.

"It's not enough to kill them on its own," Dad told me. "But taken in large quantities then eventually it would. So basically the hungrier they got the more they ate."

"OVER HERE!" Donovan shouted. She's found them!

We all rushed over to her and saw some officers carrying the two children away. They were alive!

-------- (SHORT TIME SKIP) -------

We all headed back to the Yard to question the little girl. Some officers had gone in first.

Donovan came over to us. "Right then, the professionals have finished if the amateurs want to go in and have their turn."

Lestrade stopped us before we could go in a said, "Now remember that she's in shock and she's just seven years old so... Anything you can do to..." 

"Not be ourselves?" I asked and Lestrade nodded. Well that's nice!

The three of us opened the door but as soon as the little girl saw my Dad she began to scream and point at him. Lestrade quickly pulled us out the room.

"The kid's traumatized," Lestrade told us. "Something about Sherlock reminds her of the kidnapper."

This is weird! "Has she said anything else?" I asked.

"Not another syllable," Donovan told me.

I bet she was loving this!

"And the boy?" I asked.

"Unconscious," Lestrade told me. WE HAVE NOTHING!

I left the room to go and get a drink for the dispenser down the hall and when I came back everyone was gone. I sighed, Dad's left me again!
I was about to walk past the office we were in when I heard Donovan talking to Lestrade,

"A foot print," Donovan stated. "He got all this from a foot print. None of our guys would have got that."

"CSI Baker Street what do you expect. We need them," Lestrade told her.

"Don't you think it's a bit strange how Holmes knew all the information, the girl screaming her head off when she saw him," Donovan told him. I didn't like where this was going! "Don't you think it's a bit... of a coincidence?"

I had heard enough. I ran down the halls of the station and ran outside. I need to get to the flat NOW!

Donovan's going to turn Lestrade against us!!
