The black flag

This is the third book in the Tucker Norman series. Once again, the setting for the story is Gloucester, Mass., which is the author's hometown. The title of the book is taken from a tradition of flying a black flag on a commercial fishing boat when someone has died at sea. In this mystery novel, several fishing boats return to Gloucester flying a black flag. Once again Tucker Norman and Associates are asked by local law enforcement to investigate this unusual situation. The investigation delivers the reader through a maze of complicated evidence and into a quagmire filled with strange characters, who appear to have a secondary motive for their activities. The reader, as is always the case, is dragged around Cape Ann as our sleuth tries to fit the pieces of the puzzle together.-from Amazon.
