A Rose Before Dying — Amy Corwin

The only family Charles has left is his uncle, Sir Edward. When Sir Edward is accused of murdering his mistress, Charles is determined to prove his uncle's innocence. Unfortunately, the only clues left behind are a few enigmatic roses and a note threatening to kill an unidentified victim unless the riddle is solved.

Ariadne is struggling to make a success of the gardening business left to her by her father, and when an earl, Charles Vance, tells her that a stranger's life depends upon her identification of a rose, she is torn. She wants to assist him, but If she is wrong, someone could die and her reputation as a rosarian would be ruined.

The stakes are high, but Ariadne reluctantly agrees to help the attractive earl. As the two plunge deeper into the mystery, they must fight the distraction of their growing love if they hope to prevent a killer from claiming yet another life.
