The baby's dirty, stinks to high heaven.  She hurries back to the living- room, hearing sirens and gunshots.  The detective is crouched outside a house, peering in.  Already, she's completely lost.  The baby screams at the top of its lungs.  She turns up the volume.  But it's all confused.  She hurries back in there, claps an angry hand to the baby's mouth.  `Shut up!' she cries.  She throws the baby down on its back, starts to unpin the nappy, as the baby tunes up again.  The phone rings.  She answers it, one eye on the TV.  _`What?'_  The baby cries so hard it starts to choke.  Let it.  `I said, hi, this is Jack!'  Then it hits her: oh no! the nappy pin!
