Wolf: An Allison Parker Mystery: Allison Parker Mysteries (Unabridged‪)‬

Wolf Johannsen left the killing business years ago. Settled into the sleepy Southern town of Ft. Charles, Alabama, the Swedish national runs his international consulting business remotely, traveling to Europe only as business dictates. Life is good. 

In a serious relationship with Allison Parker, a beautiful widow and mother of two, Wolf allows himself to hope that a normal life can still be his. But, Wolf has forgotten one important thing, something he was warned about when he entered the covert life, and something he was reminded about when he left the Agency. No one ever really retires from wet work.
