Intro. In a city where the darkest crimes seem to have no answer, Vikram is the brightest detective of them all. With just a few pieces of evidence he can solve cases that no one else understands, but there is one mystery that has haunted him all his life: the brutal massacre of his family as a child, a crime marked with the mysterious letters K.V. that still appear in unsolved murders. What Vikram doesn't know is that, from the shadows, someone has always been watching him. Koen, the powerful and feared mob boss, has watched every step of his life for years. To the world they are strangers to each other, but they are united by a secret marriage... and for a bloody past that Vikram has yet to discover.

"The K.V. murders."
