Mischief is as mischief does... Clara Harlow is perfectly content with her life as a teacher of art and French at the Miss Masters Finishing School, so nothing startles her more than to discover that the school is far more than it seems, and its purposes more complicated than anything she could have imagined. She finds herself accepting an assignment from the highest powers in England to use her talents for a particular mission: to impersonate the ward of the late Duke of Kirklin, gain access to the estate, and to discern how a strip of the Kent coastline there is being used against the security of England. The present Duke of Kirklin, George Russell, better known as Hawk, does not know what to make of the appearance of the former ward of his late uncle, but he is captivated by her. Her skills in art are unlike anything he has ever seen, and her company grows more agreeable with every passing day. His boring, bachelor life grows less and less appealing, and the company within his walls more perfectly suited for the place than he ever dreamed. What could possibly go wrong?

To see or not to see... Emmeline Bartlett has a secret. By day, she is the polite, proper, sometimes teacher of writing and rhetoric at the prestigious Miss Masters' Finishing School. But by night, she disguises herself as the mysterious Ears, exploring and investigating the darker sides of London, writing articles about her discoveries under a pseudonym and exposing scandals. When a handsome Spaniard crosses her path, Emmeline discovers new adventures in London by night, as well as new dangers. Teodoro de Vickers y Mendoza isn't sure what he is going to do with the title he inherited from his estranged English grandfather, but he's come to England to find out. Meeting Ears on a nighttime walk isn't part of the plan, nor is finding her intriguing, exciting, and beautiful. The further he gets into her world, the more he wonders about his own, and the less certain he is about everything. Except for her.

To thine own side be true... Minerva Dalton is an experienced operative among the Agents of the Convent and not easily ruffled by the nature of her work. But when the first social event of her assignment is interrupted by another operative using the same alias surname as her own, she has to make a sudden adjustment that changes the course of both missions. And that of her life. Griffin Russell did not expect the surprise that was Minerva when he'd taken this assignment, but he was not about to argue with a woman who was stunning as well as dangerous. He takes up an unlikely partnership with her to protect them both from discovery and failure, and discovers just how skilled and accomplished an agent she truly is. Working together, can they accomplish both missions and not kill each other in the process? Or will something far more complicated and far less expected arise from their predicament?
