"The Other French Detective," by O'Neil De Noux, in Alfred Hitchcock's Mystery Magazine, November/ December 2022.
My friend and fellow Sleuthsayer, O'Neil De Noux, has series characters at work in different periods of New Orleans history. Sometimes they will investigate crimes in the same building, a century apart.
In this clever story it is 1877 and police detective Jacques Dugas is in demand because he is one of the few officers in the mostly-Irish force who speaks French. Galjour, a police inspector from Paris, has just arrived. He speaks no English but he is seeking a French prostitute who killed the wife of a government official and is believed to have escaped to Louisiana.
Dugas helps the French cop search the city's brothels but things get more complicated the next day when another Frenchman arrives, also claiming to be Inspector Galjour. Of course, this is long before the days of photo I.D.s and instant indetity checks via the Internet. And then it turns out that the woman both men are after may be a victim rather than a killer...
A twisty story I enjoyed a lot.
