This was a entertaining read. It really dates the introduction of e-mail (1990) into the world. Or as it is called in this book, "electronic mail." Frank and Joe are investigating the the strange poisoning of a friend of Frank's, who runs his own web server. Phil Cohen helps the Hardy boys on the case. And some comedic flair added as Joe is against learning anything about computers, but eventually comes around to realization that computers can sometimes aid a detective. ( )
