The Mysterious Miss Lydia by Maggie Dallen

Miss Lydia might be shy, but she’s also clever. So clever, in fact, that one might suspect she’s up to no good…

The nice young gentleman she meets in the park certainly believes she’s hiding something. He mistakes her reticence for something devious. And now suddenly this very bookish, quiet young miss is something she never expected to be…mysterious.
But it’s the nice young gentleman who’s truly keeping secrets. And he might not be as nice as he’d seemed. Soon the two are playing a game of cat and mouse…and only the most clever and mysterious can win.
