Adam Hawksmore has been forced to sneak into his own castle. The Earl of Kerrick fought in France against Napoleon, and now he's wanted for treason. The government believes he's a spy known as The Leopard. Adam doesn't expect to find anyone in his home, let alone Lady Rebecca Marche, his guardian's daughter. Adam has to recover from his wounds before he can start hunting for clues to the identity of the real spy. How much trouble can he expect from Becca?

Becca Marche and her aunt were sent to Kerrick Castle to prepare it for its new owner. That was just an excuse to prevent Becca from eloping with a poet. Becca's not sure if she's pleased with Adam's 'return from the dead' so to speak, but when she hears his story, she's willing to help him. Her determination to remain an independently thinking woman, is about to get her into hot water, but she won't back down until she's helped Adam find the real spy.

Peggy Waide has some fun with a hero who is disguised as a poet but can't create a verse to save his life. Adam is more concerned with hiding his real identity and getting on with his investigation. Leave it to a dog to give him away. Becca's ideas of women's rights often get in the way of her safety, but they add to the plot and her parents' unexpected arrival complicates matters even more.

Secondary characters prove to be dangerous, both in the potential bedroom and the ballroom. Humor is woven into this story when Adam is busy dodging female interest. Trying to figure out who is friend or foe, isn't easy, while red herrings are strewn on several trails. No matter where the characters lead, Mightier Than the Sword will keep you entertained from beginning to end.
