The Small Hours of the Morning reminded me of Patricia Highsmith’s The Cry of the Owl. The approaches to story telling and eventual reveal are old fashion. Perhaps this is because both authors were born in the 1920’s hence as they developed as writers their styles represented the time, which was gentler. You will not find the gory imagery depicted in present day mysteries. The writing is quaint and slow. All the characters are overly exaggerated. The smarmy ladies man, dense detective and clueless husband are all ridiculous characterures. I prefer modern day authors that entrance the readers were their truly terrifying, twisted tales.
