For clarification purposes since I am just joining now. Bear with me please T_T.
1. Is the condition of the house well-maintained? Such as whether the bolts, etc were rusty or worn-out.
2. The dining area is on the table that is near the couch or is it in the kitchen?
3. Is it possible for a human to be hidden in the closet? If so, can the human be undetected?
4. Was the cousins asleep when the murder occurs or were they awake?
5. Did the murder occur in the morning or the night/what time did I slept?
6. The victims all died in their bed, which is in the view of the window, correct?
7. Was the perfect seals for 1 of the doors broken by the person who was checking up on his cousins?
8. Is the detective and the person(Who is known as you in the story) the same person? Who is this detective who just appeared? O_O.
9. Were there any items in the drawers at all? If so, are there any that could possibly be used to fabricate or perform a 'perfect seal' condition without the natural implements provided?(Bolts, lock on window)
