The book was perfect. Loved the dialogue, her first impression of him, the realistic friendship among the women, the fact that the police didn't have it all together from the first moment. I did guess who the killer might be, but it wasn't at all obvious, but also made perfect sense. 
 It is fun to read slightly older contemporaries and see/remember what the technical limitations were - no instant access to computer files from anywhere, heroine without a cell phone, etc. 
 The list was a fun exercise to get the girlfriends away from thinking about their relationship problems, and it did get into size and performance, but the first 5 or 6 items had nothing to do with sex. Sam made sure to warn her about the sex items "I've got nothing for show and tell" and "the first time will be 5 seconds" type comments. Then when he said "I can't believe I missed this" about their arguing, I was lost! What a great hero.
