The Secret of the Dashing Detective by Ellie St. Clair

Lady Juliana knows she is in danger. But does she really need a bodyguard?

One abduction and suddenly her brother, the Duke, begins treating her like a damsel in distress. Lady Juliana, however, is anything but – she is a woman who knows her own mind, and is determined to make a difference. But just how is she supposed to work for her secret society protecting animals when she is being followed around by a dashing detective?
Matthew Archibald has taken on many jobs in the past, but never did he think he would be playing nursemaid to the spoiled sister of a duke. Little does he realize, however, that there is much more to the fiery, spirited woman than he initially thought.
Matthew soon finds his focus wavering as he tries to determine just who is threatening the Remington family. But the closer he comes to Lady Juliana, the less he is able to stay professional. Will his growing feelings for her come to endanger them both?
