My little detective

My 6 year old just walked into the den and dropped off several notes saying, "I found these around the house."

One says "Rob, you will be sorry. Wa ha ha. Mr. X."

Another says, "Rob, Safty is histry. Mr. X"

And "Rob, I am on your trail. Mr. X."

Perhaps I shouldn't have bought her that boxed set of Babysitters Club Mysteries...

Um, she just came back in and took the notes and said,

"Excuse me, I need to check these for DNA."

Oh boy!!!
