In the book he has a clock:
"To his great astonishment the heavy bell went on from six to seven, and from seven to eight, and regularly up to twelve; then stopped. Twelve. It was past two when he went to bed. The clock was wrong. An icicle must have got into the works. Twelve.
He touched the spring of his repeater, to correct this most preposterous clock. Its rapid little pulse beat twelve: and stopped."
Obviously drop-shipped then I take it...
