I don't know that I've read any of Charlaine Harris's Aurora Teagarden series prior to picking up Sleep Like a Baby, but if it's any indication, I might have to start searching for the rest of the series.
We open with Aurora Teagarden trying to comfort her new baby while coming down with the flu and her husband Robin getting ready to leave for a convention. The illness means calling in some extra help in Virginia, a babysitter they'd used previously after Sophie was born. Her half brother Philip is also around to help, although since he's much younger and in high school, his ability to help is somewhat limited.
This arrangement works well enough until the night Virginia vanishes and while searching for her, Philip and Roe find a dead body in the back yard. A dead body who used to be one of Robin's stalkers, who also previously tried to kill Roe.
Which quickly makes Robin a suspect, even though he's been in Tennessee.
Anyway, as the book progresses and we hear about several auxiliary characters, we do eventually find out what happened to Virginia and who killed the stalker.
It's a well written read. While it may not be Dame Agatha levels, Miss Christie also was much more interested in the mechanics than the emotions. Given this is series mystery, the emotional bonds help give this some oomph.
