The dilemma

You knock hard on the glass. Her eyes open, then close. On the dash there is no note and no number, just a prescription slip from the chemist with today's date on it. At the edge of the trolley bay there is a loose paving stone, and up at the shop doors a crowd has gathered around something you cannot see.

Your options

1. Grab the paving stone and break the far back window.
2. Try all four doors and the back first.
3. You stand there with your hand flat on the glass.
