Daniel reached a place where he could see the light of London shining through gaps among trees. The lambent sky was dissected by the spidery black X of the sixty-foot refracting telescope, supported by a mast scavenged from a tall ship. As he neared the crest he diverted to the right, instinctively avoiding Flamsteed, who exerted a mysterious repulsive force all his own. He was likely to be awake, but unable to make observations because of the light in the sky, therefore more irritable than usual, perhaps scared. His apartment's windows had solid wooden shutters that he had clapped shut for safety. He was holed up in one of the tiny rooms, probably unable to hear anything save the ticking of diverse clocks. Upstairs, in the octagonal saltbox, were two Hooke-designed, Tompion-built clocks with thirteen-foot pendulums that ticked, or rather clunked, every two seconds, slower than the human heartbeat, a hypnotic rhythm that could be felt everywhere in the building.
