Someone to Watch Over Me is the first in Lisa Kleypas' Bow Street Runners series. Vivien Duvall is rescued from the icy waters of the Thames by Grant Morgan - an infamous Bow Street Runner. To their mutual surprise, Vivien is experiencing amnesia. Grant quickly determines - based on the bruises around her throat and the huge lump on her head - that someone had attempted murder on the beautiful Vivien. He offers her a sanctuary in his home as he takes on the case of identifying her attacker.
Further adding to the muddle of circumstances - Vivien, in her pre-amnesia life - is a very worldly courtesan. One who Grant had met and been physically attracted to but turned off by her nasty attitude. The post-amnesia Vivien is delightful, engagingly intelligent and acts like a blushing virgin. It's all rather confounding, to say the least.
Once Vivien is feeling well and over the worst of her injuries - Grant takes her to a ball to let her attacker know that the murder attempt was unsuccessful. In the midst of trying to solve a crime - Grant and Vivien fall for one another, of course. And then they learn even more surprising details about Vivien and her past.
I enjoyed this book and feel that anything by Lisa Kleypas is sure to be a winner.
