Crossed Roads - An Ensley Markus Mystery, #5 ebook by Peggy Staggs 
Life has decided to be kind to Ensley and Jack. Their relationship is going great. And as a bonus, no one has tried to kill either one of them in almost six weeks.

That is until Don March, Ensley's former fiancé shows up at Jacks front door. He's there to deliver new information and to try to get Ensley back. Don isn't the only one to come to town. The Sullivan brothers enter the mix. Jerry blames Jack for his brother Dave's death. He is set on killing Ensley to make Jack suffer the way he has. Dave Sullivan, the man everyone thought was killed on a mission in Africa four years ago has come to even a score with Jack.
