Some men find it hard to kill...Others find it easy. When the city of Boston is terrorized by a mass murdering psychopath who is leading a militia of men into a war on citizens rights to privacy, its up to the fabled, yet broken Detective, Frank McKenzie to bring them to justice. What turns out to be a routine terrorist attack soon becomes a deadly personal game of cat and mouse between Conner Chase and Frank McKenzie. McKenzie has never been one for fancy suits or ties. Conner on the other hand is more of a sophisticated killer when it comes to dress code. One things for certain, both men are Casual Killers. The Casual Killer is the first book in the Detective Frank McKenzie series. First published under the title "Boston Blood" in 2012. Warning: For adults only: Contains Strong Language, Graphic Violence, Sexual scenes & Adult Themes throughout
