DEATH TO THE MAFIA is as dumb and sloppy as you would expect a Marksman novel to be. It opens with a half-page introduction that was probably hastily slipped into the book at the last minute explaining the absence of Terri White, a character from Belmont Tower's two previous Marksman novels. Probably whomever "Frank Scarpetta" was this time was unaware or didn't care about the Terri White character, leaving it to the editor to clear up the continuity problem.
1973's DEATH TO THE MAFIA, the sixth Marksman book, opens with Magellan on his way to Los Angeles to kill some mobsters there. Along the way, he's waylaid by several carfuls of gunsels who open up on him on a desert highway. He kills them all, but has to rescue an innocent bystander, Doris Sims, and take her along for the ride in his Cadillac. More gunmen pursue Magellan to Carlsbad Caverns, but he manages to kill them all--and several innocents--by starting a panic two miles underground.
Hilariously, the Marksman drops Doris off at home after this, never to be heard from again. The next 115 pages contain his real mission, which involves disguising himself as a black man (!) and posing as an HEW official in Watts! He kills many more people on his journey to waste Big Man in L.A. Frank (the Bump) Bommperone.
Obviously, this is mindless trash, but it's amusing how silly, violent, and sloppy it is. In Magellan's "black" disguise, he visits a local official, but this has no bearing on his quest or his cover. In fact, there's no reason for this scene to even exist. Frankly, there's no reason I could see for this disguise to exist, except to make the book weirder. I guess that's a good reason, come to think of it.
