Tainted

"It's her isn't it"
Another body was found but this time it was the body of one of the most dangerous yet important figures within the crime world and his body lays here with a single white rose stained by his blood her calling card.

"Detective Sloan she left something else this time" heading over my partner handed me a note with a kiss stain

"This man laying before you has tainted something as beautiful as a white rose to something that is almost unrecognisable and now it's time to return the favour
Catch me if you can babe
xoxo
Visha"

"Detective Sloan what does Visha mean"
"It means the deadly poison Detective Rose and it looks like she has come out to play"
