I believe it was already mentioned that "APTX 4869" is a wordplay on Sherlock Holmes's name.
I noticed now that you can also take Vermouth's two names, Sharon (シャロン Shi-Ya-Ro-N) and Chris (クリス Ku-Ri-Su), combined to form that same Shi-Ya-Ro-Ku. Coincidence? Maybe. Important? Probably not. (Except if the one that chose the name has something to do with Vermouth...) Regardless, I wanted to share my findings. Thanks.APTX 4869 is a pun on "Sherlock Holmes". 4869 can also be pronounced "Shi-Ya-Ro-Ku" (シャロク Sharoku), which translates into Sherlock. (http://www.detectiveconanworld.com/wiki ... ame_origin)
PS: Is there a difference between wordplay and pun?


Edit: I just remembered, aren't there people who think that Vermouth is Karasuma's wife or daughter/descendant? (Explaining why she is the boss's favorite.) If that's the case, then they could have named her Sharon/Chris purposely, because he's a Sherlock Holmes fan (or his descendants). I always manage to fit things together, even if I don't believe in the theory myself
