At length a plan of action occurred to me, and backing quite close to Tars Tarkas I unfolded my scheme in a low whisper, keeping my eyes still glued upon my end of the room.
The great Thark grunted his assent to my proposition when I had done, and in accordance with my plan commenced backing toward the wall which I faced while I advanced slowly ahead of him.
When we had reached a point some ten feet from the secret doorway I halted my companion, and cautioning him to remain absolutely motionless until I gave the prearranged signal I quickly turned my back to the door through which I could almost feel the burning and baleful eyes of our would be executioner.
Instantly my own eyes sought the mirror upon Tars Tarkas' back and in another second I was closely watching the section of the wall which had been disgorging its savage terrors upon us.
I had not long to wait, for presently the golden surface commenced to move rapidly. Scarcely had it started than I gave the signal to Tars Tarkas, simultaneously springing for the receding half of the pivoting door. In like manner the Thark wheeled and leaped for the opening being made by the inswinging section.
