No Vacancy — Amy M. Bennett

The murder of a conman turns Corrie Black from sleuth to suspect in this third Black Horse Campground mystery from the author of No Lifeguard on Duty.
 
Corrie and her Black Horse employees are celebrating their first “No Vacancy” day of the summer, when an anonymous note arrives and puts a damper on the festivities. It warns Corrie that if she doesn't close the campground on Saturday her life will be in danger.
 
Though Sheriff Rick Sutton and former undercover narcotics detective J. D. Wilder begin an investigation, Corrie will do anything to protect her friends and livelihood. But when one of her guests is stabbed to death, his true identity makes her a suspect in his murder.
 
Corrie never could have guessed that the victim was a former friend of her late father, a man known for his land-swindling schemes and string of wives across the southwest. His murder reveals decades-old secrets and lies that will make Corrie question everything she thought she knew about her parents and her past.
