When a man arrives at the Bleecker Street Inquiry Agency, anxious to hire them to find a missing heiress, Eunice Holbrooke realizes her past has finally caught up with her...and that she may no longer be able to hide under the disguise that has kept her safe for so long.

Arthur Livingston's goal in life is to make his mark on the world as a mining industrialist, but after the man who could help him achieve his goal is murdered, Arthur feels compelled to seek justice for the family - but he's left with more questions than answers after the eccentric Bleecker Street Inquiry Agency refuses to take on his case.

Desperate to conceal her real identity and avoid the irritatingly handsome Arthur, Eunice takes on a different case that requires her to go deep undercover and entangles her in one troublesome situation after another. When other secrets come to light, Eunice has no choice but to confront her past, hopeful that it will set her free but knowing it could very well place her life - and the lives of those she loves - in jeopardy.
