The Shifty Minion. The Shifty Magician, #2

Black magician, Damien Rathschild, is still Shelton "Shifty" Sharpe's master. Shifty was only allowed to come back because the infusion process gave him special talents Damien finds useful. Luckily, Damien needs Shifty to work in the field in order to exercise his talents properly, so he's not kept in captivity anymore. However, Damien's standards are still high, and he demands results. As far as, Damien's business associates are concerned, none of Damien's employees last long or are seen again after he dismisses them, and no one will miss Shifty if he gets "terminated." Can Shifty survive his probation if he doesn't have the ruthlessness he needs to engage in black magic?
