"The Right Size of Favor," by Joseph S. Walker, in Sleuths Just Wanna Have Fun, edited by Michael Bracken, Down and Out Books, 2025.
This is the fourteenth story by my friend and fellow SleuthSayer to be reviewed here. The nearest competitor has twelve.
Hard Line Graham is a legendary private eye of the classical tough guy school. Unfortunately, he's not the op handling this case. Instead we have:
"My name is Josh Branson. I'm a seventh-grade English teacher, and I'm married to Hard Line Graham's daughter. I didn't get a summer school assignment, and Hard Line doesn't like people sitting around, so he told me I'm working for him. He sent me here because he owes somebody a big enough favor to help Brenda Roman, but not a big enough one to show up himself. I have precious little idea what I'm doing and I'm frankly terrified."
The Brenda Roman mentioned above is the firm's client, the county coordinator for Hands Across America, a campaign to raise money for charity. (All the stories in this book are tied to some actual event from the 1980s.)
Someone is demanding a share of the money raised for charity: a protection racket. Our teacher-turned-P.I. has no trouble finding the gangsters but they may not be so easy to deal with: "Christ, this guy's huge. He looks like he bullies offensive linemen for their lunch money."
That's good writing, sharp and funny. You'll find a lot more like it before Josh finds a solution in this delightful story.
