twelve o'clock Saturday night
She certainly had been a good sport last night . But this was n't the time to consider that . He had a great deal more important matters to think of now . He had to find out how he could make it perfectly plain to the world that Mark Carter had not shot a man after twelve o'clock Saturday night at the Blue Duck Tavern . And as yet he did n't see any way without incriminating himself as a kidnapper . This cut deep because in the strict sense of the word he was not a kidnapper , because he had n't meant to be a kidnapper . He had only meant to play a joke on the kidnappers , and at worst his only really intended fault had been the putting up of that detour on the Highway .
