Heres a formula I use for thesis statement: There are (number of body paragraphs) main (Word Choice: causes, ideas, reasons, thoughts) behind (subject you are discussing) that I will discuss. They are, (list topics for each body paragraph).
OR
There are many (Word Choice: Ideas,causes,thoughts, reasons) behind (subject you are discussing). I will be discussing the (number of body paragraphs) main/most important ones which are, (Body paragraph topics)<span />
They are interesting and could even be mysterious. What if in the note there is important information that I need more details of? What if it’s a secret that I must know who told it? Some people use anonymous notes to just ask questions but I believe they could be telling the things in their life that they will never say out loud. It’s a scapegoat for some but others a night mare. You could get a letter that a family member is dead by the killer? But I would want to know who? Where? How? Why? This is why anonymous notes are so interesting and mysterious.

Explanation:
There's not always an adjective in a prepositional phrase, but if there is one, it's the word before the noun.
EX: He walked through the large entrance.
Prepositional phrase- through the large entrance
Preposition- through
Object of the preposition (noun)- door
Adjective- heavy
