An Agent for Arielle - Pinkerton Matchmakers, #11

A mulatto heiress, a former slave, and the case that tests their resolve... Mulatto heiress Arielle Bradford refuses to marry the politician her father has chosen for her. When she sees an advertisement that the Pinkerton agency in Denver, Colorado is looking for female recruits, it seems like the perfect escape plan. And then she discovers she has to marry her training agent. Former slave and Union spy Caleb Smith is leery of his beautiful but fiery partner's ability to be a good agent, but when a prominent Negro politician receives a threat on his life, it's up to both of them to find the would-be killer.
Can a woman who has never known shackles of slavery and a man who has never taken his freedom lightly not only work together, but maybe even find love?
