Unable to see a way out of his predicament, he plunged into abstract philosophy, attempting to find an escape in metaphysics, and on 24 June he started writing a long essay to express his ideas. Inspired (in a misguided way) by the work of Einstein, whose book "" he had aboard, the theme of Crowhurst's writing was that a sufficiently intelligent mind can overcome the constraints of the real world. Over the following eight days, he wrote 25,000 words of increasingly tortured prose, drifting farther and farther from reality, as "Teignmouth Electron" continued sailing slowly north, largely untended. Finally, on 1 July, he concluded his writing with a garbled suicide note and, it is assumed, jumped overboard.
