"As of today, the coroner hasn’t discovered what killed Caballo. The most credible theory I’ve heard is Chagas disease, a tropical parasitic infection that gradually weakens the heart. Caballo had told me about weird fainting spells he’d had over the years, and not long ago he’d felt so listless and feverish that he thought he’d contracted West Nile. Both symptoms could indicate Chagas. But just writing those words makes me feel pompous and stupid, because it’s exactly the kind of thing that would make that cut-the-crap grin creep across Caballo’s face. "
