Sherlock checked the clock on the mantle it was 8:00 he turned to speak to Luna "come on you time for bed".

Luna started to whine "but im not tired" she complained crossing her arms and stomping her feet.

Just then Louise came in "your fathers right you start back at school tomorrow come on off to bed and we better tell your brother aswell now say goodnight".

Luna gave her dad a kiss on the cheek and made her way up the stairs with her mother. Louise tucked her in and gave her a kiss on the cheek before going into Nova and Sherinfords room to say goodnight to Nova. She saw that the door was ajar and found it strange, Nova never closes a door or even attemps to unless told, she entered the room and scanned it to find that it was empty.

Panicked she raced down the stairs, "SHERLOCK!" she shouted as she raced as fast as she could with the cast on her leg, sherlock came out of the living room.

"What is it?, Whats wrong?" Sherlock scanned her face trying to deduce the problem to no avail it always frustrated him that he could never deduce anything from Louise but i suppose thats what kept there relationship interesting because he never knew what to expect with her.

"Its Nova his gone, i went to check on him and tell him to get to bed but his not in his room." Louise said tears streaming down her cheeks, "I bet its him, my good for nothing brother, he said it himself children are easy to manipulate". She clenched her fist suddenly over taken by a rush of anger coursing through her veins, "we have to find him Sherlock".

Sherlock held her close "dont worry we will find him." Sherlock pulled his phone from his pocket and scrolled through his phone and pressed the call button his phone rang twice before another voice could be heard on the other side.

"Hello Brother, this better be important because im half way through a pile of paperwork thats due tomorrow"

"Its Nova, his been taken and I know you put a tracker in his phone now if you can find time in your busy schedule can you please perform a scan and find out where he is"

There was silence between the two brothers before sherlock heard Mycroft typing away on his computer "according to my trackers his at the park at the top of baker street maybe he went there for a bit and lost track of time".

"Thanks" Sherlock said and hung up, "Mycroft said his at the park, I will go and fetch him you go into the living room and rest we will both be back soon" he kissed Louise on the lips before grabbing his scarf and coat and made his way down to the park.

It was 8:15 when he arrived he walked around and found no sign of Nova, reaching into his pocket he dialed Novas number and hit call hoping that he would answer, thats when he heard it, AC/DC's highway to hell echoed through the empty park.

Thinking the worst he ran towards the sound to find Novas phone lying in the bin, he picked it up and unlocked it scrolling through the messages on the phone till he found one from an unknown number he read it and it hit him. Moriarty has his son, he made his way back to 221b phoning Lestrade and John on the way, this was a rare case, Sherlock Holmes needed help.
