midnight
It 's very effective , somehow . '' Across the gulch the Kohlers ' little house slept among its trees , a dark spot on the white face of the desert . The windows of their upstairs bedroom were open , and Paulina had listened to the dance music for a long while before she drowsed off . She was a light sleeper , and when she woke again , after midnight , Johnny 's concert was at its height . She lay still until she could bear it no longer . Then she wakened Fritz and they went over to the window and leaned out . They could hear clearly there .
