"Neither have you, Marian. You intend to go along with me, ostensibly to help me in whatever I intend to do. That's fine. I'll accept it. But you know good and well that I intend to carry on and on until something cracks. Now, tell me honestly, are you going along to help me crack something wide open, or just to steer me into channels that will not result in a crack-up for your side?"

Marian Harrison looked down for a moment; I didn't need telepathy to know that I'd touched the sore spot. Then she looked up and said, "Steve, more than anything, I intend to keep you out of trouble. You should know by now that there is very little you can really do to harm either side of our own private little war."

#And if I can't harm either side, I can hardly do either side any good.#

She nodded.

#Yet I must be of some importance.#

She nodded again. At that point I almost gave up. I'd been around this circle so many times in the past half-year that I knew how the back of my head looked. Always, the same old question.

#Cherchez le angle,# I thought in bum French. Something I had was important enough to both sides to make them keep me on the loose instead of erasing me and my nuisance value. So far as I could see, I was as useless to either side as a coat of protective paint laid on stainless steel. I was immune to Mekstrom's Disease; the immunity of one who has had everything tried on him that scholars of the disease could devise. About the only thing that ever took place was the sudden disappearance of everybody that I came in contact with.

Marian touched my arm gently. "You mustn't think like that, Steve," she said gently. "You've done enough useless self-condemnation. Can't you stop accusing yourself of some evil factor? Something that really is not so?"

"Not until I know the truth," I replied. "I certainly can't dig it; I'm no telepath. Perhaps if I were, I'd not be in this awkward position."

Again her silence proved to me that I'd hit a touchy spot. "What am I?" I demanded sourly. "Am I a great big curse? What have I done, other than to be present just before several people turn up missing? Makes me sort of a male Typhoid Mary, doesn't it?"
