This book in the series had a sense of the mundane about it. Nothing gripping or exciting apart from the abduction of Stone at the end. I liked that. It made the characters real and believable. The prime suspect also drifts into ambiguity. Again a nice touch that keeps the reader plodding along with Stone and Dehan. The only downer was why Helena was not noted as not being on the flight to Denmark. Did I miss something?
