Loved the Lee Child Reacher books and read them all at least twice. Not so much now...I used to read them at pace...they were hard to put down but No Plan B was difficult to read...almost boring. I addition, research is faulty. Chloroform is used in one scenario whereby a dealer is subdued in seconds with no mention of a struggle. Seemed unlikely so I read up on Chloroform. Supposedly takes 5 minutes to make a person unconscious using Chloroform. Andrew Child has his character doing it in less than 10 seconds.
