Andrew is spending an evening in Bob's house on a stormy winter night when the power goes out. Andrew locates a candle and a box of matches in Bob's living room and lights the candle so he can see. While Andrew searches the house for Bob, a sudden thunderclap startles Andrew, causing him to faint. The candle Andrew was holding falls to the floor and sets a nearby stack of papers on fire, which is left unchecked and ultimately causes significant damage to Bob's house.

Has Andrew committed arson, as defined in common law? Explain your answer.
