question:  What is the relationship between Polk and Walsh? What is the central complication in their history together?
context: Perhaps there was method in Colonel Walsh's madness—murder-madness—when he ordered Major Polk to scan the planet for a guy named Joe.

We were somewhere in Area Two on Earth, takeoff point for any operations in Space II. The rest was gravy, and Colonel Walsh wasn't going to let me get by with gravy. "It will be a simple assignment, Major," he said to me, peering over his fingers. He folded his fingers like a deck of cards and dropped them on his desk as if he were waiting for me to cut.

It was just like Walsh to ship me off to a strange place. He'd goofed off on a pile of uranium that could've, and almost did, blow the barracks sky-high that night. The trip to Venus came off without a hitch. And I thought about Colonel Leonard Walsh and how he was supposed to be quelling that revolt. Ever since Walsh had taken command, ever since he'd started pushing the natives around, there'd been trouble. Big plants and small ones, some blooming with flowers I'd never seen before, and some as bare as cactus. His features, his muscles, everything seemed to have been stretched like a rubber band.

"Yes," I said, still thinking of Colonel Walsh.
