about one in the morning
I remained in the same state of splendid isolation for the rest of the evening . There was no difficulty about keeping watch , for as soon as the sun went down a large obliging moon appeared in the sky , lighting up the marsh and the Tilbury road almost as clearly as if it were day-time . I could have seen a rabbit a hundred yards off , let alone anything as big and obvious as a Scotland Yard detective . At about one in the morning I turned in for a couple of hours ' rest . I felt that if Sonia had gone straight to the authorities they would have acted before this , while if she was sleeping on her wrath there was no reason I should n't do the same . I had given up any expectation of McMurtrie until the next morning . I woke at half-past three , and resumed my vigil in the pure cool twilight of early dawn .
