When I moved to the area and saw the postbox and phonebox combo I was excited to add to the A Fine Pair series.
Unfortunately, the phonebox was not of the correct type allowed in the series.
So here is a spin-off series.
To work out the co-ordinates for the cash you will need to retrieve information from the phone box:
A - the first digit of the landline number
B - the second digit of the landline number
