The train crossed the River Tay, took a sharp right in the direction of Dundee, then suddenly veered off the track to avoid a herd of deer. Somehow it managed to jump back onto the track again almost immediately afterwards.
P and I did not discuss this incident. We were too busy listing all our complaints about a recent meeting of the British Computer Society.
When I looked up again I saw that P had transformed into a pale woman with fluffy dark hair.
