midnight
It is my idea that he looked , at these times , for a heavenly signal , either a meteor or some strange appearance of the heavens . It was known that he was a poor sleeper , and spent much time at night wandering around . On the night of the crimes it is probable that he performed his devotions early , and then got the signal . This is evidenced by Singleton 's finding the axe against the captain 's door before midnight . He had evidently been disturbed . We believe that he intended to kill the captain and Mr. Turner , but made a mistake in the rooms . He clearly intended to kill the Danish girl .
