I had found the heel of Achilles! “While Gregory was occupied with his other two antagonists I dealt a sudden stroke with the axe at his right hand, but missed, the weapon falling heavily upon his chest. My first emotion was disappointment at having missed my mark but in another second I realized that the blow had disabled him. The left arm hung useless at his side, but what prowess it lacked was made up in the increased activity of the legs. He ran, and never have I seen such speed. He would have made Atalanta resemble a snail! However, three against one put the odds too heavily in our favor. Between lurches and thrusts at the flying figure I managed to convey to the two policemen my discovery in regard to his mortal points, and we soon had his trusty right arm disabled. The rest was comparatively easy. We dismembered him. We did not want to kill him, but it was soon apparent to us that the damage done to the control board would prove fatal.

It was not the physical loss of my leg that brought me to this. _It was the mind that allowed it to do so._ Tell David and Rosalind I am sorry for the past, and I wish them much happiness for the future!’ Those were his last words.” David Bell and his wife looked at each other with tear-dimmed eyes.
