As James always does, she manages to develop numerous complicated characters and a multi-faceted plot. On the side of law and order the two junior inspectors are more important than Dalgliesh to the plot and the investigation. As with the suspects, their own lives and histories will play pivotal roles in the investigation and its resolution. James does not disappoint in this mystery, and the book follows patterns seen in her other Dalgliesh novels. In the end the police discover that an alibi is not quite as unassailable as it seems.
