The Project Murders, in Broad-View Acres
This is the opening of the book as a sample:
Long ago, they called him MAC, just Mac is all they would call him, his real name was not known to many except his relatives and people just automatically assumed it was his rightful name. His real name was Mark Anthony Cooper, a Detective who was great at his job and known for hunting down the worst killers in the cities’ history. He solved some of the worst murder mysteries by being patient, and persistent, plus studying clues. But his greatest tool was communication and control, Mac, never lost control on his cases even if, they drove him crazy, his cool calm, exterior and mind set made him a Detective who all wanted to be like.
