I believe Lee Child has a subtle sense of humor in his writing. It feels like he thoroughly enjoys writing Reacher stories, making the unbelievable believable, letting this giant of a man wander across the country taking out all the bad guys in his path, and painting a picture of a country he loves.
I won’t go into the plot of Past Tense. You can read about it in almost every review. But I liked it.
I’ve read most or all of the Reacher books and enjoyed every one of them.
