Doubtless they thought I was still close on their heels. A dozen steps I took, then halted. The corridor branched and I knew not which way my companions had taken. At blind venture I turned into the left-hand branch, and staggered on in the semidarkness. I was weak from fatigue and loss of blood, dizzy and sick from the blows I had received. Only the thought of Tamera kept me doggedly on my feet. Now distinctly I heard the sound of an unseen torrent.
