A Rake's Redemption

Viscount Dunnley, has decided it's time to stop being a rake and to find a wife. Since his friends have married members of "The Six," he decides to check out the remaining single ladies of the group, reasoning that if his friends found suitable wives he would, as well.
Sarah Mallory seems a likely prospect, but she tends to act a bit strangely around him, as if she doesn't like him. Theo's intrigued enough by this to focus his attention a little more closely on Sarah.
Sarah is a bit frightened by her reaction to Theo, but she's more frightened by a threatening stalker-like suitor. As she and Theo get
to know each other better, she begins to rely on him to protect her from Nasty Ned.
