A week into our affair, Severo Marquez told me he had shot his own dog. He’d already told me about his crazy female cousin who locked herself into the bathroom every Sunday and pounded nails into her hands in bloody imitation of Christ, about the jars of ears he saw in Vietnam, and his dramatic escape from Cuba—swimming across Guantánamo Bay under fire, dragging a rowboat full of relatives to the safety of the American base. I’d also heard about his Mookie-dog, part beagle, part Doberman, so smart she could carry an envelope to Severo’s mother across a mile of Little Havana, or climb a tree to find Severo in a woman’s apartment. When he said he’d shot this unbelievable animal, his dearest friend, there was a crack in his voice through which I could see him doing it, and suddenly I wondered whether everything else I’d heard from Severo might also be the truth.
