Sylvia Grey: The London Debacle

Nobody has seen the face and known the name. At least none of them have lived. The name Sylvia Grey is known by many but none can put a face to it. She hides in plain sight.

"The name's Grey. Sylvia Grey. Shame to ruin such a pretty face, but you're dead now you know that so... Bye-bye."
A single gunshot through the heart. Dead, but the shot never echoed due to the silencer screwed on the end of the gun.
