r/Punny

I am reading The Thursday Murder Club, in which the last line of this extract says that Cut to the chase is a pun, which I couldn’t understand. Here is the extract :

“I first found out that the famous trade union leader Ron Ritchie lived in the village when he and Penny’s husband, John, nursed an injured fox back to health and called it Scargill, named for the 1980s miners’ union leader. The story had been featured in the village newsletter when I first arrived. Given that John had been a vet and Ron was, well, Ron, I suspected that John had done the nursing while Ron had simply been on naming duties.
The newsletter, by the way, is called Cut to the Chase, which is a pun.”
