as for Maria's part , actually i was focusing on the events related to shinichi , and skimmed that Maria part quickly , so i have no idea
what do you think ? what does that 'bird' hint mean ?
it may be like a hide and seek game?
or would it be a real case like a kidnapping ? i don't know ?
Well, you could scroll up a bit and you would have noticed my thoughts on this part. All the other 'clues' or 'items' left in the house including the books, bookshelf, the yacht were tipped over by the earthquake indicating how strong and intense the quake must have been. Yet the 'bird' and the 'glass' holding the toothbrush and toothpaste in the bathroom were left standing. Now how could that have been? Unless their bottoms were glued so they could not be tipped over; otherwise, the items must have been picked up by someone and placed in their 'original' position rather than scattered on the floor. All the other 'clue items' were tipped over, so the event of Maria's 'treasure hunt' must have happened prior to the Earthquake. Yet, only the last\latest clue of the bird and glass were left standing, indicating it must have been returned to that state AFTER the Earthquake. Now the question is... who could have done this? If Maria went missing before the Earthquake happened, then she could not possibly be the one who did it. Could it be that there is someone else in the house who 'took care of the bird'? Could it be a trap\setup to lure the young detectives? Will have to wait for the next file to find out!
