First of all you need a protagonist who is flawed. Even Ian Fleming's, James Bond, had his flaws. Yes, he was a womanizer who drank and smoked. The same goes for Raymond Chandler's, Phillip Marlowe, who had a weakness for scotch and long-legged women. Think Macbeth or Gatsby or Jason Bourne. Very flawed indeed. Even Indiana Jones was afraid of snakes.
Second, you need an antagonist who is believable. I know we're conditioned to seeing movie villains who are simply there for maniacal reasons. They're trying to blow up the White House, or poison the planet's water supply, but why? The best antagonist has a plausible reason for their behavior. Make him/her have an underlying reason for their actions. This makes it compelling for the reader to understand the plotline and stay with you until the end.
Finally, and the most important part of the process, is the rhythm of the story. This can be characterized as a writer's style. How you negotiate the mixture of dialogue and narrative will eventually determine the ability to force the reader to turn the page. Resist the temptation to show off all your knowledge of a certain subject. If you're a gun enthusiast, don't spend three paragraphs explaining the intricacies of a 9mm Beretta. It's what the character is doing with the Beretta that matters. The ultra successful Elmore Leonard famously said, "Try to leave out the part that the reader tends to skip." That's probably the best advice. You probably never skipped over dialogue did you? I'm not saying you should leave out important details, but mix it up.
The best way to do this is to "Show not Tell." This is also a popular saying that needs to be followed. Don't say, she was mad. Show her slamming her fist on the desk. It's rhythm. It's the cadence of the story that keeps you reading. A good way to make sure this is employed is to use the 5 senses in every scene. The sound of the waves crashing on the shore as the detective searched for the body. The smell of formaldehyde during the autopsy. All of these pull the reader inside the room and place them right there in the scene itself.
If this sounds like basic stuff to you, then you're already a seasoned author with a solid grasp of the fundamentals. But as with any profession it requires talent and routine. Even major league baseball players hit off of a tee every day during the season to keep that muscle memory going. As long as you employ these features in your writing, you're bound to have a successful product on your hands. And I'll let you decide what success is, but for my money, success comes from reading your work with a smile on your face knowing you did your very best to write the story you were trying to tell.
