If you keep on going straight past the bonfire there is a ladder on your right hand side. Climb up it open the door drop down. Next there will be a door on your right hand side(enemy in wall be careful) open it and enter next room. There will be 2 manikins in the room that will drop from the ceiling once you enter the middle of the room. Once they do lure them back to the previous room and kill them near the statue so it can take in their souls. After that you make your way back to the bonfire room(if you don't die first of course). Where you climbed up the ladder the little curricular pad before it becomes an elevator which gives you the key for the next phase.
