Lee Child, as an adult writer, did not create his character, Jack Reacher

If an adult writer had wanted to create a character who bought his clothes off-the-rack and sought to make his movements hard to track by traveling on public buses, the adult writer would not have made his character six foot, five inches tall, because buying clothes off-the-rack would have been difficult, most seats on public buses would not have had room for the character’s legs, and a man who was unusually tall would have been easier to track.

My theory is that Jack Reacher was an alternate personality formed in Lee Child’s childhood.  See my past posts on Lee Child and Jack Reacher for facts that support my theory.

[Added February 8, 2022: Fans of the novels may point to major advantages of Reacher's height.  However, an author who was painstakingly creating the character would have found ways to avoid or overcome the inconveniences I cite.  More important, I refer the reader to my past posts in which I quote the author on his creative process.  He does not use multiple personality terms, but what he says amounts to the same thing.  And Reacher hears voices like a sane person with alternate personalities.]
