Book club discusses "The Janus Stone"

In April, the book club selection was the second of the "Ruth Galloway" British mystery series The Janus Stone by Elly Griffiths.  Ruth is a forensic archaeologist and college educator.  She is called upon to assist the police when a child's headless skeleton is unearthed while an old mansion is razed.  Located beneath a doorway, the skeleton rested in a building that served as a Catholic orphanage years ago.

The detective in charge of the investigation is a gruff Harry Nelson working with the horizontally challenged Ruth again for a second time.  Despite his demeanor, the two develop a bond of respect and even friendship

This case may have several possibilities as the body might be very old from the Roman-era times--related to a nearby archaeological dig--or much more recent with a story of two missing children 40 years ago.

Ruth pursues the matter with a firm determination but is hampered along the way: she is encountering credible threats to her life and she is mum about her being newly-pregnant.

Comments from the book club members included:

• bones in good preservation can offer many layers of investigation in the field of archaeology 
• the novel covers periods of British history with its archaeological digs
• although the second in the series, a recap would be helpful (and in general for series) 
• Ruth is a non-traditional lead character of a series being an over-weight person
• has the writer decided and planned well ahead for the series how to handle the implications of Ruth's unplanned pregnancy (?)
• a few read the first book of the series The Crossing Places and one read the third book of the series The House at Seas End
• good mystery book.
