Harry's dying words tell Dick to find Barry Fenaka, a guy who supposedly knows where to find a stash of stolen cash that Harry has hidden, and mention the name Vincent Palmer to Fenaka. Then, instead of dying slowly, Harry blows himself up with dynamite. As Dick flees the scene, a black van lurks in the trees.
