feelingless

Accustomed by the strictest and most rigid training, to obey as familiars, the will of their superiors without question--to be mere mindless and feelingless tools, to whom death itself was awarded, if by word or hint, or even sign, they dared evince themselves to be as other men--he had, at the command of the Grand Inquisitor, deeply drugged Senor Stanley's evening draught, and, while under its potent influence, had purloined his sword; waylaid Don Ferdinand in the Calle Soledad, effectually done the deed, and--aware that it would be many hours ere the English Senor could arouse himself from the stupifying effects of the draught--had intended returning to his chamber still more effectually to throw on him the suspicion of the murder.
