They have made a disision that they have to kill Hairless Joe if he continues to come after them. They came to that disision after he tryed to throw them down an elevator shaft. At the near end of the book they made a devastating discovery, Hairless Joe is Frank Lindineir. Frank is the "CIA" agent that suposedly was their parents boss. They now have to get him to the police alive without getting themselves killed in the process. This book is full of twists and turns at all corners. I recommend this book to everyone.
