“Thriller Award finalist McMahon’s exceptional third mystery.... McMahon plants devastating twists like carefully concealed land mines, but never allows the story line to come at the expense of plausibility. This whydunit is sure to win him new fans." (Publishers Weekly, starred review)

“John McMahon’s third offering in his P.T. Marsh detective series, A Good Kill, is without a doubt his best yet - a complex, richly drawn, and utterly propulsive story in which the stakes couldn’t be higher or the outcome more uncertain. McMahon’s deft plotting, complicated characters, and gorgeous prose are evident on every page. I raced through the story at warp speed. Put yourself in McMahon’s eminently capable hands and enjoy the ride!” (Karen Dionne, internationally best-selling author of The Wicked Sister) 

“With only three books into the series, John McMahon has gracefully dropped the needle into the groove. A Good Detective set the stage, The Evil Men Do kicked it up a notch, and A Good Kill solidified what we all knew was coming - that hard-ass investigator, P.T. Marsh is here to stay. He is every bit as relevant to a new generation of readers as Sam Spade or Mike Hammer was to the generations before us. McMahon breaths new life into characters that in the hands of a lesser writer would get lost in the glut. But not here. Not even close. This novel has every indicator that the McMahon train isn’t slowing down. A Good Kill isn’t just a good book, but rock-solid proof of the birth of one of the best new crime fiction writers in the business.” (Brian Panowich, author of Bull Mountain and Hard Cash Valley)
