because you were with the uncle and her on their call Sunday. You
discovered in some way that I had since disappeared from that
neighbourhood. Then you accidentally got on to this telephone call, and
decided to run me down. Some cute little detective, I'll say. But what's
the object? What is it you are trying to connect me up with? What
possible cause can you have for butting in on this affair?"

"I told you before; merely curiosity."

"And who was the guy with you?"

"An old servant of the Coolidge family."

"It was mere curiosity in his case also, I presume?"

"So far as I know, yes."

Hobart smiled, showing his teeth cruelly.

"West," he said slowly, "you are a damned good liar, but I am about to
spike your gun. Go on out Mike, and send in the first witness."

CHAPTER XV

THE EDGE OF COMPROMISE

The two men sat silently watching each other, Hobart pretending a
carelessness he was far from feeling, uncertain as to West's real
purpose. The latter realized now the true seriousness of his position,
yet this only increased his belief in the reality of the crime.
Previously his mind had harboured doubts, but the very fact that Hobart

These thoughts took possession of his mind and were convincing. He no

at that moment concentrated more vividly on his own personal peril. How
could he escape? What was he about to be confronted with? Nothing around
him afforded inspiration. He was bound helplessly; Sexton had
disappeared, whether dead or a prisoner, he did not know; the walls of
the room exhibited no signs of weakness, while Hobart eyed his every
movement coldly, evidently enjoying his predicament. Apparently the man
comprehended the nature of his thought.

"Perfectly useless, West," he said carelessly. "This place was
constructed for the purpose, and you are not the only one who has tested
its strength. You will get out when I say so, and not b
