Twenty Centavos, A Mystery Set in San Miguel de Allende. TWENTY CENTAVOS A new book by John Scherber Does an artist really see things differently? Painter Paul Zacher, preparing for a gallery show in the Yucatan, is unwillingly drawn into a murder investigation in his home town of San Miguel de Allende, Mexico. A prominent antiques dealer has been shot in the head, and a twenty centavo coin found in his mouth. Zacher draws on the help and expertise of his Mexican girlfriend, Maya Sanchez, and his retired detective friend, Cody Williams, to comb the prosperous expatriate community for clues as he tries to stay out of the way of the police. The action ricochets from the heartland of colonial Mexico to the steamy jungles of the Yucatan, as Zacher inches closer to the killer, only to find himself marked as the next victim. Twenty Centavos is the first book in the Murder in Mexico mystery series.
