Cop by day/wolf by full moon. When werewolf police detective Joshua Hobbel is framed for murder, he must accept the beast within in order to stop the human monsters that surround him.

For your consideration:

When a cursed detective struggling to control his inner werewolf is framed for murder, he must unleash his inner beast to find the true killer or be lost to his curse forever.

Three words shorter,clarifies his dilemma, sharpens the hook.
