Did ya' guess?
"FATHER!? Master, he claims your lineage! I will set him right." Fenwick cried as he grabbed a rusty pipe. Moriarty pulled it from his grasp, "no, you will not attack an ally. You may explain yourself sir."
the young man smiles, "I am Andrew Moriarty, from twenty-three years from now. Your future self sent me to aid in your current plan and remove your largest thorn. You are to use this equipment to succeed while I assassinate one, Mr. Sherlock Holmes. You may examine me if you do not believe."
Professor Moriarty smiled back, "no need, I can see from here that you are telling the truth. How, may I ask, do you plan to proceed?"
"like my father before me, very carefully." Andrew bowed and disappears.
"master, how could you believe such a story?" Fenwick cried in disbelief. "he looks nothing like you!"
Moriarty picks up a component, "if she is whom I suspect, he looks like his mother."
"Where is she?! People don't just vanish. The only way is, is if she has the same tech as our thief. And if she does then she is most likely in league with him." Lestrade seemed somewhat desperate now. Watson looked at her with concern, "or it could be that he stole the technology from her or her employers." Lestrade pouted and glared at his logic. "whatever, if you're right than I... will do my own paperwork. If I'm right than you two have to come to my next family reunion."
Watson smiles, "of course Lestrade. We would be honored to come."
she thinks, smiling evilly, "wearing an outfit of my choosing." His smile dissipates. Holmes smiles, "of course. Don't worry Watson, we have a higher likelihood of being right." He enhances the image of the mysterious girl. "find anything Holmes?" Watson asks. "not yet. all the more intriguing." he replies. Outside a hooded figure watches from an alley, smiles and disappears.
"why are you going back?" Lestrade fussed at Holmes, "someone tried to kill you this morning!" She yells, blocking the door, "what if they try again? And succeed?" Holmes pushed past her, "they shall need to try harder, as I am now on my guard." Lestrade gives up, "whatever, I'm taking another gun just in case."
"of course." he banters, "I may not need to worry about the enemy attacking me when your driving would do the job nicely." she growls and mock strangles him. After a rough ride, courtesy of Holmes' comment, they all arrived at the restaurant. The owner came out with an expression between worry and hope, "mister Holmes, so good to see you. I hope you don't blame me for the incident, if you want me to I could fire the waiter who served you." Holmes held out his hand to stop him, "that is unnecessary. I do not blame you or your staff. It was merely an assassination attempt on my person." Lestrade scoffs behind him, while the owner seemed unsure whether or not to sigh in relief. Holmes examined everything, starting with his table. It took them five hours (and several grumpy customers) to find a clue. A single hair from a crack in the floor under his rescuer's table. They bagged it as evidence and finally left after another hour with no more clues.
The hair was dyed blond but was brown underneath. Watson examined it's DNA pattern to identify the head it came from. "you two are not going to believe this." he said as excitedly as a robot could get, "but this hair came from... your daughter."
