My Lord Protector(Beresford Adventures‪)‬

On the most horrifying night of her life, Charlotte Robinson discovers the murdered body of the mysterious woman who's engaged her as a companion at a remote Cornish manor house. Then, Charlotte finds the hidden note from the dead woman that tells her to flee, to change her name, to not trust anyone or she, too, will be killed. Along with the note is her employer's journal. She speedily packs a valise, the money she's saved, and the dead woman's journal and sets off in the dark of night. She eventually arrives in London, using the name Caroline Rutherford and manages to secure a position as a companion to the youngest sister of the Earl of Devere.
London's most sought-after bachelor, Devere has never met the woman with whom he wants to be shackled, but he becomes obsessed with his sister's companion, the quiet Caroline Rutherford, a woman of mystery. So many things about her don't add up, but nothing he says or does will loosen her tongue-not even his stolen kisses.
When she narrowly escapes a murderous plot, the terrified woman confesses all to him, and they set out to learn the identity of the murderer of her former employer . . . if only they can stay alive.
