When Cassie starts coming home later than usual, Saffi decides it's time she knew everything. She sets about investigating these strange activities, but doesn't count on the assistance of her dotty old neighbour, Ted Burgess.

If only Saffi could stop the 'sarge' from standing on her toes, then she could set things right before there's blood on the microphone!' (Publication summary)
