老太太說完故事後，已經午夜了。然而，沒有人感到疲憊，連蒂芬尼都精神抖擻地坐在那。
「真是悲慘的故事呀，外婆！」阿桃衝上前去擁抱老太太說。「我都不知道你經歷過這麼痛苦的遭遇。對不起我之前沒辦法諒解你對美國人的偏見，現在我知道原因了！」
「看來我們得儘早解決這個案件。」傑佛瑞說。「根據您的故事，阿雄的怨靈是27年前被封印在罈子裡的，這罈子一直都在你身邊嗎？」
「是的，它從未離開過我的住所，不管是在紐約還是西貢，」老太太答道。
「這麼多年都沒有發生什麼事，直到一個月前嗎？」孝恩問道。「那表示一個月前有人將封印解除了。只是，問題是誰？」
經過了一番詢問，神探們終於找出是誰了。事實上，是女僕阿花一個月前在打掃地下室時不慎將罈子打翻，使得符咒脫落。
「阿花，你怎麼不早說？」阿蘭生氣地用越語說。「我們就不用繞這麼一大圈了！」
「太太，我很抱歉！」女僕說。「我不敢說，因為怕你們會開除我！」
After grandmother Mai had finished her story, it was already past midnight. Nevertheless, no one felt sleepy at all, even Tiffany, who pretended to be constantly yawning was actually wide awake. A long agonising silence lingered in the air, where no one knew what to say.
"That was such a tragic story, grandmother!" exclaimed Thao as she dashed to hug her grandmother. "I never knew you've gone through such....such painful experiences. I am sorry I couldn't understand your grudge against westerners, now I can see clearly your reasons."
"Sorry to interrupt," said Jeffrey, frowning. "But in order to solve the mystery, we need to get back to business. According to your story, Hung's ghost was properly sealed in the cremation urn 27 years ago; and the urn has never left your possession since then."
"No, it has always been in my house, whether in New York or Saigon," answered grandmother Mai.
"And nothing strange happened all this time until about a month ago?" interrogated Shaun pensively. After grandmother Mai replied in the negative, Shaun concluded, "That means someone must have broken the seal about a month ago and released the spirit. But the question is: who?"
After some more interrogation, the detectives finally discovered this person. In fact, it was the maid who accidentally knocked over the urn when she was cleaning the basement a month before, causing the seal to be detached from the urn.
"Why didn't you tell us before, Hoa?" scolded Lan furiously in Vietnamese. "You could've saved the detectives so much time and work!"
"I'm so sorry, madam," answered the maid. "I dare not speak the truth in fear of being fired."
