An innocent young telegraph operator becomes a counterfeiter's target. Once, the Lamartine Hotel was a quiet refuge for New York's stuffy fashionable set. But by the 1890s, fashion has moved uptown, and the lobby of the Lamartine has been overtaken by natty young sports, who pass their afternoons with billiards or shows of noisy derring-do. Their preferred damsel is Lila Williams, a delicate young telegraph operator whose shyness so charms them that they resolve to defend her against any ill-behaved characters. They are about to face their fiercest challenger, who rides in the gleaming armor of a millionaire. His name is John Knowlton, and from the first telegram she writes for him, Lila is charmed. He has money, good looks, and a criminal secret, and his insidious charisma will demand heroic effort from the knights of the Lamartine billiard table.
