There is something very wrong about following a vengeful JFK in pursuit of his killers but Craig Frank is willing to go there in his graphic novel, “JFK: SECRET OPS.” It is dark humor to be sure. What makes it work is Frank’s unabashed commitment to stay the course. Okay then, giddy up, pardner, cause we’re on a bumpy conspiracy theory-laden crazy ride. Where do I find these unusual works? Well, it ain’t easy but it’s fun.
