Anyway, the story: an off duty police detective is in a football stadium watching a game when he spots a suspect (above) in a kidnapping case he's investigating. The rich parents paid the ransom and the child was promptly returned as agreed, but the suspect escaped and the money wasn't recovered.
The detective follows the man back to his apartment, cuffs him and, on an impulse...even though he's never done anything like this before...he demands half the ransom the 'napper took for the child. The kidnapper is appalled. The unfairness of it rankles him. After all, he did all the work so why should he get only half the pay? A fight ensues and the two roll around the floor, battling for the cop's gun.
There's more to it, but I'll leave it at that. It's an interesting story because the corrupt-only-once detective and the "wronged" kidnapper are both strangely ethical in their own way.
The next story (above) takes place on a lonely path near a lake. A man's boss believes he's having an affair with his wife. The employee is innocent and he's hoping to clarify that as they walk along a lake at night, but when he turns to talk to his boss...he isn't there.
After a futile search the man calls the police. They look and find nothing, then the wife shows up and claims the employee had threatened to drown her husband that very day. It's a frame-up! Is the boss still alive? Did the wife kill him? What's the employee to do?
The next story (above) is about a boys' summer camp in the 1950s. Every camp has at least one boy who doesn't quite fit in and who's ridiculed by the other boys. In this camp the adults made the mistake of giving the kid a .22 rifle for shooting practice. You can imagine what happens.
The kick in the story is that it's told from the timid boy's P.O.V., and he's not honest with himself. It's hard to know exactly what went down because the narrator isn't reliable. The writer raises the question: could a murderer who really believes his own innocence ever be found guilty of a crime?
Lastly, here's (above) a story about a sentimental crook and his beloved mother. The crook hires a hit man to bump off a pesky business partner, and the whole thing is discussed in front of the crook's mother. She doesn't seem to care, she's just concerned that the two men eat their chicken soup and bundle up when they go out.
The story seems straightforward enough at first, then the mother is slowly revealed to be cagey and calculating, and maybe something worse. It's the kind of crime story O'Henry would write, if he wrote crime stories.
