When Lady Marianne Bentley arrives in town to find out that her close friends has disappeared without an apparent trace she is stunned to find no one seems to be doing anything about it.  She visits the girl’s parents and finds them less than enthusiastic about an all out investigation.  She decides that she will find her friend in spite of them.  She is surprised to find out that the last person to see her was her neighbor the Marquis (Thomas), with whom she has never been cordial with.  In the hope of solving the mystery she decides to become better acquainted with him.

She is taken off guard by his charm and sincerity.  She finds herself falling in love with Thomas.  Can the two find happiness or will Marianne’s suspicions cause irrevocable differences?

The Mysterious Marquis was a fun and sweet story by Ms. Cogan.  If you are looking for an older (mid 20’s) heroine in a London historical that you will want to pick up The Mysterious Marquis.  I enjoyed how the author was able to weave in all the misunderstandings that would potentially happen if people don’t talk and make assumptions.  I think The Mysterious Marquis is a story that fans of the genre will love.
