Have you ever known someone who just kept hammering and pounding away at a point long after it had already been made? Was his name Ichihashi Fumiya, by any chance?
Miyazaki Tsutomu committed his abductions and murders of four very young girls back in 1988-89. In the summer of 2001 his death sentence was upheld by an appeals court. It is only a matter of time before he finds himself dancing a very short jig.
This book has as its premise that a certain mysterious scenario (regarding motive) was deliberately quashed by the police in order to make Miyazaki look like a monster and turn public opinion against him. If in fact they did, it was hardly necessary. The defense never argued that Miyazaki didn't commit the heinous crimes he was charged with, and the crimes were more than enough to enrage the public without any police manipulation.
About half of the book consists of background information on Miyazaki as a child and a young man. There are plenty of enlightening details about him and his world prior to the murders. The other half, unfortunately, is dedicated to hammering the reader with basically the same information over and over again in an attempt to show how he has uncovered some behind-the-scenes police finagling and that Miyazaki has only been faking mental illness in order to avoid ending his worthless life swinging on a length of government rope. He never quite comes out of the shadows enough to make the first point. He rails on and on about the second point so much you almost with they'd free Miyazaki just to spite this guy. When I got within 10 pages of the end of the book, I just really didn't care anymore. I had to force myself to finish it.
If you're interested in the Miyazaki case, look elsewhere. Give this one a pass.
