S1·E55 Elementary, My Dear Pan

Peter and John pretend they are the greatest detective partners of all time: Sherlock Holmes and Dr. Watson. The mystery they are trying to solve concerns the disappearance of Peter's pipes. The two boys follow odd clues and twisted lines of deduction all over Neverland in search of the missing instrument. They are captured by the pirates during the adventure and sentenced to drown in the rising tides, but Peter signals the mermaids to come to their rescue just in time. The duo solve the mystery when Peter's complicated line of reasoning leads him to remember that he let Hard-to-Hit borrow his pipes a few days earlier.
