With a Little Bit of Death

Spelled into Silence.

Before Clarence was a man possessing a bob cat, he was a murder victim. Now that he’s beginning to trust Geoff, he’s revealed a little of his background…and asked Geoff to find his murderer.
Geoff can either do the legwork himself or unlock the spell that keeps Clarence from telling anyone who hurt him.
What nefarious magic is meddling with Clarence’s free will and why?
