On the way back, the officers were discussing with each other. "Helen does not seem to be lying. I have checked the medicine John took, and they were all exactly the same as the doctor's prescription. According to Helen's statement, she gives regular doses every day, and the doses are also exactly the same as what the doctor prescribed. From the maids, we also learned that Helen is a very careful and patient person."
"I did not find any problems with the maids I interrogated either. There are several maids who have access to the medicine, but they don't seem to know anything."
"It seems we need to continue the investigation. If the murderer is not hiding in this house, then we can only say that this murderer is a master at hiding."
"Leave two men here to watch this place and see if there are any suspicious movements, especially by Helen and a few maids who have access to the medicine. Oh, and that Chris Fowler too. He's also another main suspect now."
