This was the most engaging Ruth Galloway mystery yet. So many threads were introduced including the experience of living rough (or being homeless), gender issues in the workplace, broken marriages and affairs, motherhood, religion, the theater, etc.
Ruth is called in to examine bones found underground while Nelson is told about a missing woman who lived on the streets and the plot thickens. Is there truly an underground society or is it just a utopian dream? Why are the murders and disappearances growing in number? All is brought to a most satisfying conclusion by the end of the epilogue with room for future growth in the series.
I would recommend this book to mystery lovers, especially those with an interest in archaeology and/or police procedure.
