Read it through once

One minute—two minutes—three minutes of this, then we heard a long deep groan, and everybody sprang up and stood, with his legs quaking. It came from that little dungeon. There was a pause, then we herd muffled sobbings, mixed with pitiful ejaculations. Then there was a second voice, low and not distinct, and the one seemed trying to comfort the other; and so the two voices went on, with moanings, and soft sobbings, and, ah, the tones were so full of compassion and sorry and despair! Indeed, it made one’s heart sore to hear it.
