Penner is at least on par with Grisham regarding accuracy) of the rules of evidence in a criminal trial and trial procedure. Penner comes out ahead, in my opinion, in that he doesn't misstate legal rules for dramatic effect the way Grisham sometimes does.
The writing is tight, the pace is consistent. I would like to have seen a little more character development. The female characters were defined chiefly by their body type and style of clothing.
The male lead character is a senior assistant district district attorney tasked with the prosecution of a guilty murder defendant with no physical evidence and his only witness is a juvenile co-defendant. The rules protecting a defendant from being forced to give testimony against one's interest would prevent that co-defendant/witness from giving evidence, whether they are tried together or seperately. This is further complicated by the juvenile issue. Penner does an excellent job of describing the legal issues that confront his hero.
In classic form, the day is saved by a surprise witness that the hero is able to put up because um...er...THE name was on the witness list given to the defense, but neither side expected this person to be called!
But that is not the heart-stopping conclusion that I won't reveal.
Overall, it is a great read. The legal issues are accurately presented. My minor caveates aside, I still recommend the book highly and look forward to other titles from Mr. Penner.
