While Sister Rose Callahan is an interesting and unexpected detective, this book only barely makes it into my "recommend" column. The material on latterday Shaker communities is fascinating and seems to be presented honestly. The members of the Shaker community are shown to have faults and doubts regarding their faith and the larger community is shown to have prejudices toward the Shakers. The attractions and difficulties of living among Shakers are nicely presented. However, the mystery is barely passable. Wordworth does not play fair with readers who like to predict the solution to the mystery. She presents almost no definitive clues and introduces vital information late in the story. Knowing this book is the first in a series also raises questions: Will there be frequent murders among the peaceful Shakers? How will Sister Rose manage to get involved in enough mayhem, while remaining an observant Shaker, to justify a series? I'll read the next one in hopes it is a better mystery, but I won't anticipate continuing the series if it is not.
