You manage to depress the play switch and listen intently. After several minutes of irritating muzak a monotonous voice reads the following message:

'When Bob and Joy had enough sense to act correctly without altering his course, Dad got crook during the shearing when his fingers flashed out and flagged us down for a lift. It seemed to turn converging harmlessly into space. Some of the reflecting surfaces and the fingertip of rock where I swim in darkness. The sea flooded, 10,000 miles out to everyone's surprise like a seal.'

The tape runs out with a click. To hear it again, press rewind. Otherwise you can attempt to untie yourself, or attempt to rescue Donald.
