Angels Undercover by Diane Noble (Mystery and the MInister's Wife, Book #6)
History comes alive in Copper Mill when Civil War reenactors come to town. But when valuable historical memorabilia belonging to Caroline Beauregard Johnston's grandfather, a Confederate hero, disappears from a display at the Copper Mill library, Kate vows to help the brokenhearted Caroline find answers. Break-ins around town raise fears, but not all the burglaries are as sinister as they appear. A mysterious note, a suspicious request, and a long-buried secret lead Kate on a roundabout search for the truth. Meanwhile, a debate about worship music just might tear Faith Briar Church apart. With some members ready to split, can Paul hold this fractured church together? As they struggle to keep peace in the community, Kate and Paul realize that sometimes God sends angels where you least expect them.
