ten o'clock
Inquiries and investigation showed that Lauer , a trusted employee of Winckel , had taken a last look at the prisoners at about ten o'clock . He was certain of that ; he had heard their voices , although he could not make out what they spoke about . There were sighs of relief from Schmidt and O'Reilly , who felt that the situation was covered , but Winckel was more skeptical and less canny . `` I will admit that they were here until ten o'clock and later . I will even admit that they were not listening at the conference . But how was their escape managed and why after ten ? Did they have outside help and how did the outside help know of their imprisonment here ?
