Trick or Trick?
4 May 2013 | by mitchrmpSee all my reviews

It's Halloween Eve and Laura and Mary get to go to town and soap the Olsen windows. Don't worry though, they have both Mr. Olsen's and their father's permission to do so. But what starts our as a trick suddenly turns into a horrific, frightening experience when Laura believes that she witnesses Nels chop of his wife's head during an argument. Of course, nobody would believe her. Mary thought she was insane. Charles wouldn't even let her get a word out about it, and Caroline thought Nels was just playing a trick on her.

Of course, what they don't know is that Nels sends her to visit her mother early the next morning. For some unknown reason, Nels puts hires someone to drive her instead of putting her on the stage. This leads to even more trouble. Laura tells Nellie and Willie about it, but they don't believe her until that night...Oh, but Nels quickly assures them.

Nellie and Willie tell Nels they would tell Laura and Carl the truth, but instead Nellie decides to play a trick on them. The next day, Nels purchases some manikin pieces and starts bagging them. When Laura and Carl spy, they see Nels putting them into a bag and mumbling that her legs wouldn't fit...

Nightmares cause Laura's frights to intensify. Her dreams are quite frightening, and probably would indeed frighten the weak at heart.

The ultimate Halloween prank of all times is pulled off by Nellie and Willie. They convince Laura and Carl to come to the basement in the store where they claim their father had been digging. I won't give any more details, but it's definitely one for the books! In the end, the truth is revealed, proper punishment is rendered to the guilty persons, and the episode ended much as it begins...
