Joe's ex-wife Vivian moves back into the neighborhood with her new husband, Billy Buss, who appears to be a good thirty years younger than Herself (that is Vivian, or Vi as she now wants to be called).  This is not good news to Judith, but soon it becomes worse than she could have ever imagined.  At a neighborhood block party, Vi announces she is going to tear down her house and build a condo.  This is not welcome news to the residents living on this quiet and peaceful cul-de-sac.  Following the block party, the body of an unidentified man is found strangled to death in Vi's back yard, not one-hundred feet from the the B&B. 

Even after promising to not get involved in this murder case, Judith sets out to try and figure out who killed the man nobody knows and why.

Viagra Falls is a fun, fast-paced amateur sleuth.  The characters are charming and lots of fun.  I feel that Renie's eccentric behavior went a little too far in this latest of Mary Daheim's Bed and Breakfast Mysteries.  Overall, I enjoyed the book and found the mystery unraveling in it to be well plotted. I found it to be a very enjoyable book to read.
