In the close-knit community of Chatham, Massachusettes, young men are being murdered without logical reason.
Martha, "Marty" Nickerson is an assistant DA in Cape Cod. She feels a sense of accomplishment when the jury finds the defendant, Manuel Rodriguez, guilty of killing college student, Michael Scott.
With the guilty verdict in, there is a sigh of relief in the community but shortly thereafter another body is found. When the autopsy on this body is performed, there is a Roman numeral II scratched on his chest. Marty doesn't know the explination since the killer is in jail.
In close communities sometimes relationships prevent an attorney from working on a case. That is the situation with the second murdered victim so another attorney in Marty's office takes the lead.
Marty still wanted to do something to help and when the defense attorney of the man accused of the second killing, asks Marty to accompany him to speak to the accused man, she agrees. When Marty gets the details and questions the evidence, she informs her boss, Geraldine Schilling. Schilling is furious and accueses Marty of working with the defense to undermine the prosecution's case.
There is a good description of the internal politics of a prosecuting attorney's office. It is also admirable that Marty feels her first obligation is to justice where her boss feels differently.
I enjoyed the story but found it more cute than suspenseful. Marty was a somewhat interesting character but much of the material here has been done before.
