Murder At the Watergate by Margaret Truman

The glittering cast of characters includes Vice President Joe Aprile, who plans to become president, if he can avoid a tempting vice; a glamorous Washington hostess and fund-raiser, Elfie Dorrance, with a propensity for marrying rich and powerful men and then grieving prettily at the end - their end; and Chris Hedras, a special assistant to the vice president, with some very special ambitions. And, of course, Annabel Smith, gallery owner, and Mac Smith, law school professor. The story deals in part with the influence on political campaigns of "soft money" and its hard consequences, as well as this country's tortuous and often ambiguous relationship with Mexico, in particular the glorious San Miguel de Allende, home of the well-to-do, and a few ill-to-do, a place involving drugs, politics, and police and politicians looking the other way.
