"Dead Even," by J.R. Sanders, in Killin' Time in San Diego, edited by Holly West, Down and Out Books, 2023.
A nice private eye story. I can't quite figure out when it takes place, except that Hollywood is swarming with B-movie cowboys. One of them is a friend of our narrator, P.I. Nate Ross, and that friend has a friend and business partner named (all right, nicknamed) Pooter. Pooter has two things of great interest: a ton of money and a girlfriend named Cassie Plumm.
Nate, "being both by profession and disposition [a] suspicious guy" thought she might be more interested in Pooter's bankroll than his charming personality. Then Cassie comes to him for his professional help. A former boyfriend is threatening her and she wants Nate to eliminate him. Nate doesn't specialize in the kind of elimination she is hoping for but he is willing to look into the matter.
I won't go into detail about what happens but it hits a lot of the classic hardboiled dick motifs. And it's a fun read.
