"This Budge Kennedy," I evaded, "we must find him. We have time.
One clue may lead us on. Tell me what you know of the Blind Spot."

"Very easy," he answered; "you have it all. I have been here a
number of years. You will remember I fell into the case through
intuition. I never had any definite proof, outside the professor's
disappearance, the old lady, and that bell; unless perhaps it is
the Rhamda. But from the beginning I've been positive.

"Taking that lecture in ethics as a starter, I built up my theory.
All the clues lead to this building. It's something that I cannot
understand. It's out of the occult. It's a bit too much for me. I
moved into the place and waited. I've never forgotten that bell,
nor that old lady. You and Fenton are the only ones who have seen
the Blind Spot."

I had a sudden thought.

"The Rhamda! I have read that he has the manner of inherent
goodness. Is it true? You have conversed with him. I haven't."

"He has. He didn't strike me as a villain. He's intrinsic, noble,
out of self. I have often wondered."

I smiled. "Perhaps we are thinking the same thing. Is this it? The
Blind Spot is a secret that man may not attain to. It is
unknowable and akin to death. The Rhamda knows it. He couldn't
head off the professor. He simply employed Dr. Holcomb's wisdom to
trap him; now that he has him secure, he intends to hold him. It
is for our own good."
