Shezmu by K A Sands

Tau Shez is a complicated man.
He was no longer the young man who had crouched at his father’s grave and wept, nor was he the young man who had left a broken hearted mother in tears. Tau was a man driven to reinvent himself in order to find what had been stolen from him, and he left everything behind for his cause.
His pathway to hell was not so swift, neither was it painless, and years in the making. Nothing else mattered.
Tau scoured the ends of the earth, walking dark streets, invisible to most. Slinking in the shadows, he’d wait until the time was right. With a khopesh in one hand, his heart in the other, Tau would deliver his deadly blow on the cusp of an affliction he had no desire to temper.
Going back to Egypt changed the way Tau saw his life.
Bruce Bensen is a simple man.
He wasn’t looking for salvation, nor was he looking for a partner. He wanted a way to live his life without the constant nightmares plaguing his sleep. Finding Tau had been a beautiful coincidence. Among the sea of red clouding Tau’s vision, and a chord which simply just struck, Bruce thought he might have found salvation anyway.
Answering Tau’s call changed the way Bruce saw his life.
They were monsters in the dark, a terrifying alliance, searching for the same thing. They watched each other bleed, Bruce revelling in Tau’s depraved sense of morality, his sadistic mindset capturing Bruce and holding him fast. Bruce wasn’t willing to let Tau go.
As one, they were formidable. Together they caused chaos.
Their mutual goal?
A Ghost.
