Interesting short story collection subtitled "A Detective's Story in Ten Cases" revolving around Private Inquiry Agent John Dorn.
From the Blurb:
John Dorn's Yellow Pages ad says "Private Inquiry Agent".
That's what his father used to call himself - before his business went under and his wife left him... and he drank himself to death.
But John's not going to end up like his father. He doesn't have a wife, or much business. He doesn't really drink either. Not yet.
