"Hiding in Plain Sight," by Tom Larsen, in Black Cat Weekly, 193.
Most of Larsen's stories are set in Ecuador. Some feature a cop but this is from his other series about private eye Wilson Salinas.
Our hero explains that a big part of his job is hunting down gringos who have come to Ecuador to hide from governments or other agencies.
All my clients wanted from me was a location where they could find the subject of their search. "We'll take it from here," was the common response when I located someone. I had a standard disclaimer that I gave all my clients stating that if they were after someone to beat them down or kill them, I wouldn't help. I doubt if any of them even read it.
Now he's looking for John McIntyre who ran a jazz club in New Orleans that laundered money for the mob. Finding him is easy; surviving an encounter with the man's bodyguard is harder. But then it turns out that nothing about the case is as it appears.
A twisty and satisfactory tale.
