Chasing the Violet Killer — R. Barri Flowers

Seven unsolved homicides.
Can they prevent the next?

Traumatized after witnessing her relative's murder live on video chat, Secret Service agent Naomi Lincoln makes the long trip home for the funeral. Years ago she left boyfriend Dylan Hester brokenhearted, but now she must work with the handsome detective to investigate a string of murders and bring the criminal to justice. Putting aside the attraction that never went away will be difficult enough. But capturing the elusive Violet Killer, especially once he sets his sights on Naomi, will be the greatest challenge of their professional -- and personal -- lives.
