Query: Worst True Crime Book I've Ever Read

I've read at least 30-40 true crime books and this is easily the worst I have ever come upon. Badly written (doesn't your publishing company have editors, Mr. Flanagan...?), the research is even worse. Events will be given and dates and times mentioned, then subsequent events are stated to have occurred later, although the times listed are earlier...?!?!The crimes themselves occupy less than 5 pages of the book and they aren't even interesting. There are plenty of great true crime books out there, so DO NOT buy this piece of trash !!!
