Nelson is impressed by Ruth’s professionalism, and he makes an impression on her too: “He was an odd man, she thought, brusque and unfriendly, but it seemed as if he had really cared about that little girl.” It’s this caring, perhaps, that sees her ready to help.
Then another little girl goes missing, and Nelson asks for Ruth’s input on the letters he has been regularly receiving, letters telling him in the vaguest terms where Lucy, and now young Scarlet, are. The letters are filled with a mixture of strange references: biblical, Norse legend, literary, Greek legend, pagan and archaeological, and successively take an increasingly exasperated, at times almost taunting, tone at Nelson’s failure to find the missing girls.
This specialised knowledge means that, if the letters are actually from the killer, suspicion falls on certain people who were in the area ten years earlier: Ruth was on a dig with colleagues and volunteers, excavating a beach henge; a group of Druids were part of a protest against it. Could one of these seemingly gentle, nature-loving souls be a murderer? A grisly find on her doorstep then has Ruth wondering if she’s being warned off.
Griffiths tells the story using Ruth and Harry as her main narrators, with occasional passages from the perspective of a captive girl. The plot is believable, the archaeology interesting and the characters 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 little surprise that will ensure readers are eager for the second instalment, The Janus Stone. An outstanding debut novel.
