In the second section of In Cold Blood by Truman Capote, entitled Persons Unknown, it is shown that Perry is driven to find easy money. In section one, The Last to See Them Alive, it is revealed that Perry keeps a large quantity of treasure maps with him, and dreams of going to Mexico to search for treasure. In section two, Capote writes of Perry that, "the big question, and source of heartache, was what to do with his much loved memorabilia - the two huge boxes heavy with books and maps, yellowing letters, song lyrics, poems, and unusual souvenirs...there were some things too precious to chance losing....Perry looked through old letters, photographs, clippings, and selected from those the mementos he meant to take with him...there were half a hundred other items he had decided he must take with him, among them his treasure maps" (125-146). Of all of the old letters, photographs, song lyrics, poems, a netsuke, suspenders and a belt made from dead Nevada rattlers, a petrified dwarf tree from Japan, an Alaskan bear's foot, and more, Perry decides that he must take his treasure maps with him to fulfill his dream of searching for lost treasure in Mexico.
