The Detective and the Baroness by Karyn Gerrard

Detective Sergeant Mitchell Simpson’s only purpose is his job with London’s Metropolitan Police. But when he’s seriously injured in the line of duty, he has no idea what to do. So, when he’s offered a private investigation to work on while he recovers, he jumps at it. The problem? His client is the baroness who nursed him back to health…and stole his heart while doing it. And worse, she’s newly married…
After tirelessly working as a nurse for a decade, Lady Corrine Addington entered an arranged marriage to save her family from financial ruin. But it’s not long before she realizes her estranged husband is up to something, so she hires Mitchell to follow him. But even she realizes that she enjoys Mitchell’s company a little too much. Then a murderous turn of events changes everything…
