Michael Gilbert 
They Never Looked Inside [EPUB ebook] 

This novel followed ‘Close Quarters’ and once again features Inspector Hazlerigg. It is a gangster suspense thriller about the post-war black market. There is robbery, murder, and smuggling in a volume that contains all of the ingredients of a first class tale, with Gilbert’s particular trademarks of dry humour and wit, and an obvious knowledge of the subject written about with fascinating and revealing detail and description.
