At what point in Harry Potter...?

At the very beginning:The story starts when Dumbledore has Hagrid transport Harry (as a one year old) from the ruin of his parent's house over to his aunt and uncle's home. This is on the same night Harry's parents are killed and Voldemort is vanquished. It goes into more detail I *think* in the third chapter, "Keeper of the keys" when Hagrid returns to tell the story personally to Harry.
