The Lady Who Knew Too Much by Alyson Chase

He’s an ex-boxer. She sips tea at philosophical salons. And when these two opposites meet, their lives will never be the same.
Lady Juliana knows someone is trying to kill her father. The problem is getting anyone to believe her. Her father thinks she’s imagining things. Her brother that she’s seeking attention. And the man her brother hired to bring her back home…well, he thinks nothing much of her at all.

Brogan Duffy has clawed his way up from the streets to become the lead investigator on his very first inquiry case. The fact that it is to retrieve a spoiled aristocrat playing at intrigue is of no consequence. Nor is the fact that she beguiles him like no other woman. He has a job to do, and he won’t let anything stand in his way, not even this illogical attraction.

But Juliana might not be imagining the threat. And when it’s her life that’s on the line, Brogan has to decide to what lengths he’ll go to keep her safe. Because in order to resolve this make-or-break case in his career, Brogan might have to hazard more than his heart. And with some gambles, there’s no going back…
