We see it all the time in television show pilots. It's up to that original episode to captivate its audience and make them come back for another week. Something has to shake things up to create an interest with the viewer, and books are no different.
So what do people want to see? It depends. Some people are drawn in by action, adventure, drama, violence, and sex. Others might be intrigued by characters, unexpected events, or perhaps the protagonist is going through something that connects with the audience. The main point is that the start of anything, whether it be a movie, book, or television show, must make the reader or viewer want more.
I always say that chapter one should start in the middle of something relevant to the rest of the story. And the Devil Will Laugh begins with the protagonist and his associate are visiting the (soon to be) editor of a newspaper. Their goal is to sway him to write articles in favor of himself and the political candidate he is backing. Meanwhile across town, the protagonist's wife is murdering the current editor, who didn't go with his wishes. This ties in with the rest of the book because violence and media manipulation are a huge part of the story. Also, this is in the middle of an action. I didn't start chapter one with the characters discussing their plan to bully the media or the protagonist having breakfast before leaving the house. I jump right into the action.
Catching a reader's attention is very important. With so many other books, the Internet, and of course, Netflix as ways to be entertained, readers can easily pass up on your novel and move on to something else. Instead, give them a reason to not put your book down.
