Dreams

'Even if we didn't find all of it, even if we found only some of it--Are you with me, Dick?' Heretofore, Dick had always encouraged him, listened attentively to his talk of maps, tales of treasure, but now--and it had not occurred to him before--he wondered if all along Dick had only been pretending, just kidding him. The thought acutely painful, passed, for Dick, with a wink and a playful jab, said, 'Sure, honey. I'm with you. All the way.' (Capote 100)

Both dreams (Perry's and Dick's) rely on trickery. Perry suspects briefly this, but dismisses it. Is his faith in Dick's loyalty so deep?

Perry has childish dreams of "maps, tales of treasure" that are opposite of Dick (as we have read before). It has never "occurred to him before" that Dick may be "pretending, just kidding him". This falsely found trust foreshadows great problems. If Dick reveals his true intentions, what will Perry do? For now he can survive on "a wink and a playful jab" but that can last for only so long. Any disloyalty from Dick is "acutely painful" to Perry.

These men have different dreams. Different dreams lead to different paths that cannot be accomplished without the others cooperation. Eventually the truth will be uncovered and everything that could go wrong, will. Once they embarked on the brutal murder of the Clutters, they became eternally connected. I believe this connection will result in a bloody ending for both of these liars.
