The Midnight Line by Lee Child

I read this in autumn 2018
I do like the simplicity of the Jack Reacher plot lines. This one starts when Reacher sees a West Piont class ring in a pawn shop window. It's a woman's, and Reacher wants to know why she gave it up.  Transpires that shes a vetern horribly injured by a road blast, in need to drugs....she'll get them whatever way she can!

Great easy read
