One point does not indicate a trend, but two do. Following on the disappointment of The Order, I was hoping for a return to form with The Cellist ... but didn't get it. The story moved along fine for 80% of the time. I started to develop a feeling that Silva was back and that The Order was just the product of a bad at the office. Then Silva took a meat clever to the story line, clumsily lopping off several promising plot twists (seriously ... her high heel???), to create space for the creation of a soap box, upon which he shamelessly climbed in an apparent effort to gain favor with (or steer clear of) the cancel culture, the American popular media and political elite. You may of chopped off a chunk of your audience too.
I've followed this gifted author from the very beginning. But today I Googled "authors that write the way Daniel Silva used to".
