As he spoke, with no sound an orifice opened in the wall behind the idol. In its cavernous depths, dark and forbidding, Roger guessed that the stone had withdrawn up or sidewise, or had turned on a pivot.

“Implements.” Roger spoke from habit, still too dazed to feel, with completeness, the horror that must soon come.

Trying to hold calm, Roger felt an impulse to scream, to beat on the callous stone, to beg for mercy.
