The Girl Who Lived by Christopher Greyson

This recent (2017) suspense novel compares well to classics such as I Married a Dead Man (film version: No Man of Her Own) ​by Cornell Woolrich, After Dark My Sweet by Jim Thompson, and Nothing in Her Way by Charles Williams. 

In each of these, the hero struggles not only with adversaries (law enforcement, con artists and thugs), but also with her or his own defects that result from a traumatic past. The conflict is both internal and external. The hero's problems are both in the present and the past. 

Greyson's The Girl Who Lived is a pleasure to read not only for the complexity of the puzzle and the intensity of the hero's struggle, but also because the prose reads effortlessly. To use a figure of speech, not an ounce of fat.
