A Little Light Mischief by Cat Sebastian

A seductive thief

Lady’s maid Molly Wilkins is done with thieving—and cheating and stabbing and all the rest of it. She’s determined to keep her hands to herself, so she really shouldn’t be tempted to seduce her employer’s prim and proper companion, Alice. But how can she resist when Alice can’t seem to keep her eyes off Molly?

Finds her own heart

For the first time in her life, Alice Stapleton has absolutely nothing to do. The only thing that seems to occupy her thoughts is a lady’s maid with a sharp tongue and a beautiful mouth. Her determination to know Molly’s secrets has her behaving in ways she never imagined as she begins to fall for the impertinent woman.

Has been stolen

When an unwelcome specter from Alice’s past shows up unexpectedly at a house party, Molly volunteers to help the only way she knows how: with a little bit of mischief.
