Killer Clone by Mary Stone

Copy. Paste. Kill.
The hunt was supposed to be over. The killer—dead.
But just hours after returning to Nashville, FBI Special Agent Stella Knox is faced with another exsanguinated corpse. A college student drained of blood, ankles bruised from where he’d been strung up like an animal in a slaughterhouse.
Just like before.
But the Pennsylvania case was wrapped up. Solved. So why is this murder a mirror image? And more importantly—who is sending the message?
At first, the differences seem small. But one detail stands out—the victim’s carotid artery was cut with the kind of precision used in embalming, as if he was being prepped for preservation rather than death. But before Stella can track down the one person who might have answers—the mortician—he turns up dead.
Now, what should have been a straightforward investigation twists into something far more insidious. Is this a copycat? An accomplice? Or something even worse?
With two murders in three days, Stella knows a third is coming. What she doesn’t know…a killer is setting a trap. And she’s the prey.
