The Matchmaker's Lonely Heart by Nancy Campbell Allen

 In the late 1800's, Amalie is one of a growing group of women trying to support themselves independently. She works for her aunt who owns a matchmaking service and romance advice newspaper. She has a crush on a wealthy aristocrat, Harold Radcliffe, and is surprised to find he is one of her aunt's clients. While overseeing a meeting with Radcliffe and a possible match, Amalie bumps into a police investigator, Michael Baker, who is observing Radcliffe for quite a different reason.  He suspects Radcliffe of murdering his first wife. Amalie and Inspector Baker team up to probe Radcliffe's past, but for different reasons. As they learn more about his past, their startling discovers put them in increasingly greater peril.

This is the first in the series that I accidently skipped over when I read To Capture His Heart. It was actually a little bit fun to read them in this order, because Ms Allen does a good job of foreshadowing elements of Book 2 in this book. Both books have similar plots--the modern female surprises the rugged detective with her wit and willingness to dive into a gruesome murder mystery case.  One thing I like about these books is that the romance between the main characters progresses without major stupid misunderstandings by either party. Yes, they have to overcome reluctance to enter into a serious relationship, but they don't add to the difficulties by being dumb.  I will almost assuredly read more in the series and I have added Ms Allen to my coveted Clean Romance Writer's lists.
