1.Foreshadowing:
is an advance sign or warning of what is to come in the future. The author of a mystery novel might use foreshadowing in the early chapter of his book to give readers an inkling of an impending murder.
Example: The guy was foreshadowing the death of Monalisa
2: Foreshadowing is the same as inference because often the criminal thinks his plan will work but it is also different because when you make inferences you think you know what you say is right, but in foreshadowing you know that you might fail or succeed.

1. On slow afternoon train
2. He was wearing a new navy blue overcoat.
Imagery helps you describe the story better so you make it more interesting. It also helps you build up more tension.
5:
1. When Billy opened the door the landlady directly opens the door, she seems to know that he was coming.
2. She also says "Its already mad up for you". She again seems to notice that he was coming so she is certainly planning something.
6: I think the climax of the story is when Billy enters the landlady's place. Because nobody knows what is happening.
7: in murder mysteries, the detective usually diagnoses cyanide poisoning by the scent of bitter almonds wafting from the corpse. The detective knows what many might find surprising — that the deadly poison cyanide is naturally present in bitter almonds and many other plants used as food, including apples, peaches, apricots, lima beans, barley, sorghum, flaxseed and bamboo shoots.
8: I dislike the ending because Weaser gets poisoned and is added to the landlady's collection.
