Jay-Pea-Eyes aka Junior Private Investigators

The Boomerang Mystery is just the right case for the Junior Private Investigators or Jay-Pea-Eyes (J.P.I.’s) to sink their teeth into.
Such a strange and unusual set of circumstances have baffled the local police. Children are reported missing but re-appear after a number of hours. They are unhurt, not harmed whatsoever and refuse to say where they’ve been.
Can these young detectives solve the mystery before the police can?
Will they find out who is behind the mystery or are they just getting further and further into danger?
Can they link the clues and put an end to the mystery once and for all? Or are they risking their own lives on evidence that police would say was ‘circumstantial’ and ‘lacked concrete proof’?
The 'Jay-Pea-Eyes' think they’ve found the ‘why’, ‘where’, ‘who’ and ‘how’.
Now they need to show just how good at this detective work they really are...
