参考文（2）：
We now know what was happening in Bell tower neighborhood. The director of the local zoo says that three monkeys escaped from the zoo and was still missing. The stuff of the zoo searched the whole zoo but couldn't find anything, except a note pastes on the cage where the monkeys used to be prisoned in. 'Come to the Bell Tower and look for us when the moon eclipses' with a drawing of a bloody death's-head on the opposite of that note. Three days later in the midnight, when the last thread or moonlight vanished and the aureola turned dark red like a bloody crescent, people came to the bell tower searching for those three monkeys. They walked through the dark, silent corridor and then climbed up the creaking wooden stair onto the top of the tower, they saw the three monkeys, being nailed on three crosses, their eyes were all opened but none of them was alive. On the floor, a sentence was written with the monkeys' blood. 'Happy Hallowmas'.
