It seems this is the appropriate forum for this, so I'll ask.
I've read what is probably in the hundred thousands of books and magazines, so sometimes I remember something I read a LOONG time ago and can't remember the title, so I'm fishing here.
There's a book about a female FBI agent or Detective or something, who is on the trail of a serial killer. The serial killer is targeting random women, raping and killing them, until they figure out that the women he is killing were all on a cruise ship at the same time. Some of them were even raped. Turns out the rapist has a baby dick, and raped women, and he wants to kill everyone who knows he has a baby dick or something. It sounds weird but it was a good book, on the caliber of Thomas Harris.
If anyone else knows what I'm talking about, I'd appreciate the knowledge.
