The Case of the Troublesome Turtle (High-Rise Private Eyes Series #4)

Mr. Paris ties balloons outside his toy store every morning. But on Fridays the balloons disappear. Who keeps taking them...and what is so special about Fridays?

This sounds like a case for the High-Rise Private EyesCase #004, to be exact, the case of the Troublesome Turule.

Because no mystery is too mysterious, no puzzle too puzzling, no crime too criminal, no trouble too troubling for ace detectives and very best friends Bunny Brown and Jack Jones.
