An old flame...an assassin's bullet...the event of the season....
November 1885
Although Penelope Hamilton Wynch doesn't especially miss her estranged husband, she does yearn for the excitement of the old days when they worked together on assignments from the Pinkerton Agency. Against her better judgment, she agrees to help him on a new case: to go undercover in the household of a wealthy industrial tycoon who's been the victim of factory sabotage and an assassination attempt, just as the family is about to sponsor a cotillion for their debutante daughter. As Pen works the case while dodging her husband's attempts at reconciliation, she encounters another old flame, who happens to be
the prime suspect
. Is she falling for a would-be assassin? Can she learn the truth before he tries again?
