John Paris is a Private Investigator based in Glasgow. He lives in a nice part of town and is financially comfortable. He can afford to indulge his tastes for good food and good wine, and when it comes to cases he can take them or leave them. That, at least, is the theory. When Paris is asked by wealthy Aldis Rowper to bodyguard his beautiful wife, he knows the wise move would be to pass. But he does not. And soon he is involved in a deadly struggle to protect Miriam Rowper from a man hell bent on her destruction----and that man is her husband.
