Protecting her was his duty. Falling for her was a risk he couldn't afford—but couldn't resist.

Lady Melody Lockwood deciphers enemy codes from the safety of her home. It is safe and predictable, allowing her to feel as though she is doing more than what is expected of a lady in High Society. However, when a leak at the agency suggests her cover may have been blown, she faces a danger she never expected.

Wesley Ainsworth, the Earl of Emberly, is tasked with protecting Lady Melody, a responsibility he takes very seriously—even when she insists she doesn't need his help. Having already lost one agent under his watch, he is determined to do whatever it takes to keep her safe.

As the threat looms closer, Wesley and Melody are forced to work together to uncover the culprit that is lurking in the shadows of Brockhall Manor. Their partnership challenges them to balance duty with the desires of their hearts. Will they unravel the mystery in time, or will their guarded hearts keep them from working together and discovering the love they both deserve?
