It never did say what his paper clues were. My first impression of Otis was that he had a big imagination, and was a little immature. I now think that he is a smart guy but still the fun loving person he always was. I learned a few new things about him in these chapters. First that he is actually a private investigator and second he's not an heir. Otis was hired by Barney Northrup, J.J Ford, and Sam Westing. In the end he and crow,his westing game partner, get married and move in the apartment above the Good Salvation Soup Kitchen.
