As long they remain on paper all's well. ;-) Sherlock always looks forward in solving a serial killer with a dance of happiness and a broad grin of excitement while clapping hands like a 5 year-old child. XD
@Lata, if you need some clues of a clever thought murder check out "Monster". It is interesting with suspence, mystery, psychology and intelligence. You need to remember things and think how the characters think, aside just watching it.
Dear Penenaites, be warned. The serial killer we're looking for may be amongst you camouflaged as a cute, innocent girl. Don't be fooled. Report any anomalies to the PPD (Penana Police Department) immediately. :P :P
@weirdguy96, Yeah, you'd better. But I can also choose some rather unconventional methods to which your martial arts would have no effect whatsoever. *smiles evilly*
