The Mephisto Club
I enjoyed the first few Rizzoli & Isles books, even though I'm not a huge murder mystery fans. Then she started linking Isles personally to suspects and victims in creepy ways, which I found a little unbelievable. Then in this book, Isles apparent fascination with death leads her to go back by herself to the house of the Mephisto Club. I just found that so stupid. I put the book down and was never interested in picking it back up.
