Playing for Blood Paperback – October 15, 2007 by Chuck Anderson 
 
Playing for Blood is like a hybrid golf club, combining a number of features. It is a mystery, detective story and golf adventure, wrapped around a search for buried treasure. Mack Thomas and Sal Cascio, a couple of retired teachers who have set up shop as private investigators, have taken on a case that winds up in a life-threatening situation involving ambitious politicians and Colombian drug smugglers.
