The Janus Stone: The Dr Ruth Galloway Mysteries 2

The Janus Stone is the second book in the Ruth Galloway series by award-winning British author, Elly Griffiths. The audio version is narrated by Jane McDowell. As Head of Forensic Archaeology at the University of North Norfolk, Ruth Galloway is called in by U of Sussex's Dr Max Grey when a dig at Swaffham produces a small skeleton minus its skull, buried under a doorway: an offering to one of the Roman gods, Janus or Terminus?

She's surprised when DCI Harry Nelson turns up there: she hasn't yet told him she's three months pregnant with his child. Ruth knows she will have to reveal her pregnancy before it becomes too obvious, and justifiably dreads the reaction of some.

Soon after, Ruth attends a demolition site at the request of the field archaeologist, when another small skeleton is found, again minus skull, again buried under a doorway, where a children's home existed more than thirty years previous. Ruth calls in DCI Harry Nelson in case the bones prove to be more recent than Iron Age, as the burial looks more modern. The developer, Edward Spens is building seventy-five modern units, and is displeased when Nelson puts the work on hold citing a possible murder investigation.

Nelson's sidekick, Sergeant Clough is convinced that in any home run by Catholic nuns and priests, there's bound to be abuse, possibly foul play, but interviews with former staff and residents show no evidence of this. What might be significant is the mysterious disappearance of siblings Martin and Elizabeth Black, in 1973.

But post-mortem evidence eventually proves the bones too old to be children's home residents, and Nelson's investigation heads in a direction that is uncomfortable for some, not that that will stop him probing where he sees fit. He is distracted, though, when he learns that he is to be a father for the third time, and not quite sure how he feels about that.

Meanwhile, Ruth has the decidedly uncomfortable sensation that someone is watching, someone apparently fixated on her, who starts leaving vaguely sinister messages and objects both at the digs and on her doorstep. Nelson's reaction is to assign DC Judy Johnson to watch over her. But after she has done some research into the former residents of the Woolmarket house, Judy needs to revisit her interview with Sister Immaculata: the ageing nun must know more than she's told so far…

Griffiths uses Ruth and Harry as her main narrators, with occasional passages from the perspective of an anonymous person apparently making blood sacrifices to appease the gods. The plot is believable, the archaeology interesting and the characters, not all of whom are what they seem, are quite convincing for all their flaws and quirks.

It is certainly refreshing to read a female protagonist who is not slim and gorgeous. There are twists and red herrings to keep the reader guessing right up to the final chapters, and a nail-biting climax in which Ruth fires a gun. Returning to this cast in The House At Seas End is eagerly anticipated.
