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's 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.
