Time's Eye by Arthur C. Clarke, Stephen Baxter

but nobody understood that I was trying to see if it was my grandmother! More recently in Lahore I came down with a fever that may have been malaria, and since then, on occasion, my ‘blue devils’ have returned. So I know how it is to be plagued by the unreal.” As he spoke to her he leaned forward, intent, his eyes distorted by the thick spectacles Josh called “gig-lamps.” “But you are real enough for me. I’ll tell you what to do about it—work!” He held up stubby fingers stained black with ink. “Sixteen hours a day I put in sometimes. Work, the best bulwark for reality . . .”
    So it went, a therapy session on the nature of reality with nineteen-year-old Rudyard Kipling. She walked away more dazed than before it had begun.
    As time passed and both parties, the Victorian-age British and Bisesa’s crew, continued to lack communications with their respective outside worlds, Grove grew very concerned.
    There were very practical reasons for this; the stores here at the fort would not last long. But Grove was also disconnected from the vast apparatus of the imperial administration, which Bisesa glimpsed in the rapid talk of Ruddy and Josh. Even on the civilian side there were local Commissioners, with staffs of Deputies and Assistants, who reported to a Lieutenant Governor, who reported to a Viceroy, who reported to a Secretary of State, who reported, at last, to the Empress herself, Queen Victoria herself, in far-off London. The British were encouraged to think of themselves as locked into a unified social structure—wherever you served you were a soldier of the Queen, part of her global empire. For Grove to be isolated from this was as disturbing, Bisesa saw, as it was for her to be cut off from the global telecommunications nets of the twenty-first century.
    So Grove began to send out scouting patrols, particularly using his
sowars
, his Indian cavalry troopers, who seemed able to cover impressive distances quickly. They reached Peshawar, where the local army cantonment and military command center should have been found—but Peshawar was gone. There was no evidence of destruction, not even of the hideous erasing of a nuclear blast that Bisesa had trained the British to recognize. There was only bare rock, a river bank, scrubby vegetation and the spoor of creatures that might have been lions: it was as if Peshawar had never existed at all. It was a similar story, the
sowar
scouts reported, when they went out to find Clavius, Bisesa’s UN encampment. Not a trace, not even of destruction.
    So Grove determined to explore further: down the valley of the Indus, deep into India—and to the north.
    Meanwhile Casey, still pretty much immobilized, likewise took on the challenge of making contact with the rest of the world. With the help of a couple of privates from a signal corps assigned by Grove, he scavenged comms gear from the fallen Bird, and improvised a sending and receiving station in a small room in the fort. But no matter how long he spent calling into the dark, there was no reply.
    Abdikadir, meanwhile, had his own projects, which concerned the peculiar floating sphere. Bisesa was envious that both Casey and Abdi quickly found useful work to occupy their time, as if they somehow fit in better than she did.
    On the fourth morning, Bisesa emerged from the fort to find Abdikadir standing on a stool, holding a battered tin bucket up in the air. Casey and Cecil de Morgan sat on fold-out camp chairs, their faces bathed in the morning sun as they watched the show. Casey waved at Bisesa. “Hey, Bis! Come see the cabaret.” Though de Morgan immediately offered her his chair, Bisesa sat in the dirt beside Casey. She didn’t like de Morgan, and she wasn’t about to give him any kind of leverage over her, however trivial.
    Abdikadir’s bucket was full of water, so it must have been heavy. Nevertheless he propped it on his shoulder one-handed, and marked the water’s level with a grease pencil. Then he lowered
