What were these books?

Here’s what I remember.

Physical Appearance:

  • Color but mostly washed out.
  • Somewhere between 50 and 75 pages.
  • Roughly 5/8” dimensions
  • Kids wore horizontal-striped shirts. Knobby knees. I’m fairly sure that the girl had short afrow-ish hair that was blond. Both kids were white.

Content:

  • One of the puzzles was related to finding a note by running a pencil horizontally over the page beneath the page where the note was originally written but has since been ripped off.
  • I’m almost certain the book started off with the kids scuba diving and their uncle (or perhaps father) simply disappearing with a cryptic note that leads them on.
  • It’s not a choose your own adventure sort of book. The book was entirely linear but expected you to solve the puzzle before turning the page.
  • I believe they at one point reach a jungle.

Publishing:

  • I’m fairly sure I was reading this in the mid to late 90s.
