Fracture: A Sylvia Wilcox Mystery - The Sylvia Wilcox Series, #2

A corpse, a missing woman, and a mysterious religious group. When Delaney Whitby doesn't return from a routine errand, private investigator Sylvia Wilcox is hired to find her. Initially, it looks like Delaney left on her own, but by the time the case reaches Sylvia's desk, the situation appears more sinister. Clues lead Sylvia out to Utah, a place she is entirely unfamiliar with. Once there, she must rely on the hearsay of Delaney's acquaintances.
Still, the trail seems to be leading to a situation that indicates Delaney may be in Utah against her wishes. Did Delaney travel to Utah on her own accord? Is she being blackmailed? Or something worse?
