The Vespers of 1610, set in contemporary Baltimore, MD, is the latest fiction from California-based author Kelley Dupuis(who once lived in Baltimore himself.) The novel explores some of the ways in which our perceptions of ourselves, of the friends we once knew and of the world in general change as we grow older. It is a long, dramatic reflection on how human attitudes and perspectives naturally re-shape themselves with the expansion of life's horizons which naturally follows the loss of youth. The novel's main character, Lucien McCarver, returns to Baltimore in his early fifties to become Chief Information Officer for Cyserve, a company that designs and builds custom software. McCarver has not seen Baltimore, or any of his old Baltimore friends, since his college days. Settling back in his home town, he re-establishes contact with three old friends from high school: Danny Doyle, a music teacher and composer busy writing his doctoral dissertation on the 17th-century composer Claudio Monteverdi; Louis Taniguchi, a cardiologist in Baltimore County; and Wayne Breedlove, a one-time high school poet now teaching English at the University of Louisville in Kentucky. As McCarver becomes re-acquainted with the friends he once knew, he must also adjust to the unavoidable fact that they, and he, are not quite the same people they were when they were young. That adjustment, and the sometimes-turbulent events which accompany it, form the theme and substance of The Vespers of 1610.)
