Dead End. Jim Nash Adventures, #11

A missing teenager draws Jim back to the scene of the crime in Mexico where Kara, his pregnant wife, was killed in an explosion aboard their sloop. He's needed the intervening two years to get over the life-changing event, but now he's ready to take another look in an effort to put it all behind him for good. He crosses the border, lands an exceptional deal on a rental car, and, realizing one of his shortcomings, hires a translator.
