mystery+elements+camparison

I read these two great mystery books, one of them is the boxcar children and the other one is attack of the mutant lunch lady. They are both diffrent and simalar in many ways.
=== One element both books have in commone is they both have a problem. In the boxcar children they didnt give us a clue what the problem was and the problem was more interesting, but in the The book of the muntant lunch lady the problem dosent catch your attention, because === it startes in the middle of the book So in the boxcar children book it gives you a clue what the problem was, but in the other book it doest do it right away.

=== My second element is clues. In the books they both have clues. But in attack of the mutant lunch lady the clues were distracting than the boxcar children. In the boxcar children the clues were hard to find then the other book. sometimes the clues solve the mystery ===

=== My third element is suspects. In the book the boxcar children they have more suspects who are trying to crack the case. In the boxcar children they solved the case at the end of the book. But in the other book its solved in the middle of the book. ===

=== In attack of the mutant lunch lady and the boxcar children they both have a problem ,suspects and clues but the athors appinoin in the boxcar children is fantastic because he used good detales and his clues were exelent and it acually felt like you werein the story and you saw what was happening in the book. ===
