seven o'clock
They put the car up during the middle of the day . `` We 'll let it rest for a while , '' said Ted , as they ran it into a public garage . `` This evening we 'll take it out again , and if we 're followed then we 'll be sure that it is Checkers , and that he is on our trail . '' It was seven o'clock when they trundled forth again . A bright moonlight night made motoring highly enjoyable , and after they had run about for a couple of hours Bud got out , saying that he was tired of the sport , and would return to the hotel , and leave Ted to take the machine back to Don Dorrington 's basement . They had been followed by the yellow car again , but in going through Forest Park they had managed to give their trailer the slip among the intricate roads and bypaths , and had seen nothing of him for half an hour . As soon as Ted had let Bud out , he hit up the speed , for the boulevard was comparatively free of traffic , and he fairly spun along to the western part of the city .
