midnight
Going around to apartments occupied by the family , Paul again rings , when the proprietor appears . Upon asking if Miss Randall were at home , Paul is startled by the information that the Chesterton rooms have been vacated . Excitedly curious , Paul inquires when and where Miss Randall moved . He learns that the rooms were vacated shortly after midnight two days before , without notice . The rent had been paid until the first of the next month , and the keys were found in the doors . The proprietor had watched from his window , but did not see Miss Randall leave the house . Two men left in the vehicle .
