Miss Cassandra Paxton is sure her brother, Rupert, did something terrible before he died, and the only way to find out what it was is to ask his former friends. After questioning Lord Deverill, she's put at ease for the moment, but she still wants to talk to others.

Lord Justin Deverill can't tell Cassandra the truth for doing so would put her in danger. However, he will do everything he can to keep his promise to Rupert of keeping Cassandra safe and hope she never finds out the truth. After two attempts on Cassandra's life, Justin is forced to take drastic measures.

Treachery, a promise to a dying man and a locket won at cards inevitably bring Lord Deverill and Cassandra Paxton together. If you like romantic mysteries, this one will warm your heart. I liked the story and the characters a lot, however I was left wanting something more.
