two o'clock
Carse had locked it from the outside ! I called to him for an explanation of this conduct , but he either did n't hear me or chose to ignore my requests , for the house remained grimly silent . Returning to bed , I managed somehow to doze off . At two o'clock I was awakened by the sound of someone 's walking in the hallway . I sat bolt-upright in bed and heard the unmistakable approach of footsteps coming down the corridor from Carse 's bedroom . The tread was stealthy and determined , and as it drew closer to my room I was conscious of a cold mask of sweat clinging to my face , because the footsteps did not sound like those of Jason Carse ! The feeling hit me and hit me again until I was left stunned with the horror of it .
