Artemis- IDing Ritual Location

  'So all we have to do…'

  'Is run a cross-reference through the weather satellites, which I already have. Believe it or not, there aren't that many ancient oaks left, if you take ancient to be a hundred years plus. When you factor in the river bend and full moon, there are precisely one hundred and twenty-nine sites to be surveyed in this country.'

  Butler grinned. Stakeout. Now the Master was talking his language.
