Sadie's Secret (The Secret Lives of Will Tucker #3)
Kathleen Y'Barbo

Louisiana, 1890--Sarah Louise "Sadie" Callum is a master of disguise, mostly due to her training as a Pinkerton agent but also from evading overprotective brothers as she grew up. When she takes on a new assignment with international connections, she has no idea her new cover will lead her on the adventure of a lifetime.
Undercover agent William Jefferson Tucker is not looking for marriage--pretend or otherwise--but his past is a secret, his twin brother has stolen his present, and his future is in the hands of the lovely Sadie Callum. Without her connections to the world of upper-crust New Orleans, Jefferson might never find a way to clear his name and solve the art forgery case that has eluded him for years.
Only God can help these two secret agents find a way to solve their case and uncover the truth about what is going on in their hearts.
