Ten o'clock
My terrors appeared , even to my own mind , greater and more importunate than the circumstances authorised . It was extraordinary that Mr. Spurrel should be abroad at this hour ; I had never known it happen before . His bed-time was between nine and ten . Ten o'clock came , eleven o'clock , but not Mr. Spurrel . At midnight I heard his knock at the door . Every soul in the house was in bed . Mr. Spurrel , on account of his regular hours , was unprovided with a key to open for himself .
