at which he had decided that he would end "the game" by committing suicide. His observations over the next 80 minutes are generally cryptic and/or incomplete, but include hints such as: It is unclear from the spacing whether "11 20 40" was the time of his last entry, or whether it runs on from the preceding wording as his intended time for his ultimate action. Likewise, while the phrase "IT IS THE MERCY" is obscure, most commentators have accepted that it signifies his relief that, at last, he is leaving an unbearable situation. Tomalin and Hall conjecture that included in his last writings (not all reproduced above) were sentences that cover Crowhurst's internal debate over whether or not to leave the evidence of his actual, rather than faked, journey for posterity to see, and that he decided that the former was the better course; in the event, it was the "true" logbook that was left behind, and the "fake" one (if it ever existed) disappeared, along with the vessel's chronometer (its case was found empty), and Crowhurst himself. The disappearance of the vessel's chronometer (clock), apparently following Crowhurst's final diary entry, remains unexplained. Disappearance and presumed death Crowhurst's last log entry was on 1 July 1969; it is assumed that he then either fell or jumped overboard and drowned. The state of the boat gave no indication that it had been overrun by a rogue wave, or that any accident had occurred which might have caused Crowhurst to fall overboard. From his apparent state of mind as indicated by his most recent logbook entries and philosophical statements, it seems likely that he deliberately decided to take his own life, possibly in an effort to become a "second generation cosmic being" according to his belief (and thereupon have no further need for his earthly body), although the possibility that he met with some sort of accident, intending to return to continue writing in his logbook, cannot be completely dismissed. Three logbooks (two navigational logs and a radio log) and a large mass of other papers were left on his boat to communicate his philosophical ideas and to reveal his actual navigational course during the voyage. The boat was found with the mizzen sail up. Although his biographers, Tomalin and Hall, discounted the possibility that some sort of food poisoning contributed to his mental deterioration, they acknowledged that there is insufficient evidence
