rrival had driven into his own mind.
"Gave me the creeps, too. Makes me surer than ever that he has an
abominably deep purpose in using his wits to hang on here. He suggests
resources as hard to understand as anything that has happened in the old
room. You'll confess, Bobby, he's had a good deal of influence over
you--an influence for evil?"
"I've liked to go around with him, if that's what you mean."
"Isn't he the cause of the last two or three months nonsense in
New York?"
"I won't blame Carlos for that," Bobby muttered.
"He influenced you against your better judgment," Graham persisted, "to
refuse to leave with me the night of your grandfather's death."
"Maria did her share," Bobby said.
He broke off, looking at Graham.
"What are you driving at?"
"I've been asking myself since he came back," Graham answered, "if
there's any queer power behind his quiet manner. Maybe he _is_ psychic.
Maybe he can do things we don't understand. I've wondered if he had,
without your knowing it, acquired sufficient influence to direct your
body when your mind no longer controlled it. It's a nasty thought, but
I've heard of such things."

I tell you I did feel Howells's body move under my hand."
"Don't misunderstand me," Graham said gently. "I must consider every
possibility. You were excited and imaginative when you went to the old
room to take the evidence. It was a shock to have your candle go out.
Your own hand, reaching out to Howells, might have moved spasmodically. I
mean, you may have been responsible for the thing without realizing it."
"And the disappearance of the evidence?" Bobby defended himself.
"If it had been stolen earlier the coat pocket might have retained its
bulging shape. We know now that Paredes is capable of sneaking around
the house."
"No, no," Bobby said hotly. "You're trying to take away my one hope.
But I was there, and you weren't. I know with my own senses what
happened, and you don't. Paredes has no such influence over me. I won't
think of it."
"If it's so far-fetched," Graham asked quietly, "why do you revolt from
the idea?"
Bobby turned on him.
"And why do you fill my mind with such thoughts? If you think I
