"Yes," he said. "Technical reasons."

"Couldn't we visit this scientist you mention? Brannart Morphail? And ask him?"

He didn't want to lose her. His love for her had grown profound (or, at least, he thought it had, not being absolutely sure what "profound" meant). He shook his head emphatically. Also there were indications that she was beginning to warm towards him. It might be quite soon that she would agree to become his lover. He didn't want her sidetracked.

"Not possible," he said. "Particularly since, it seems, you didn't come in a time machine. I've never heard of that before. I thought a machine was always required. Who did you think it was abducted you? Nobody from my age, surely?"

"He wore a hood."

"Yes."

"His whole body was hidden by his garments. It might not even have been a man. It could have been a woman. Or a beast from some other planet, such as those kept in your menageries."

"It really is very strange. Perhaps," said Jherek fancifully," it was a Messenger of Fate — Spanning the Centuries to bring Two Immortal Lovers Together Again." He leaned towards her, taking her hand. "And here at last —"

She snatched her hand away.

"Mr. Carnelian! I thought we had agreed to stop such nonsense!"

He sighed. "I can hide my feelings from you, Mrs. Amelia Underwood, but I cannot banish them altogether. They remain with me night and day."

She offered him a kind smile. "It is just infatuation, I am sure, Mr. Carnelian. I must admit I would find you quite attractive — in a Bohemian sort of way, of course — if I were not already married to Mr. Underwood."

"But Mr. Underwood is a million years away!"

"That makes no difference."

"It must. He is dead. You are a widow!" He had not wasted his time. He had questioned her closely on such matters. "And a widow may marry again!" he added cunningly.

"I am only technically a widow, Mr. Carnelian, as well you know." She looked primly up at him as he stalked moodily about the footplate. Once he almost fell from the locomotive so great was his agitation. "It is my duty to bear in mind always the possibility that I might find a means of returning to my own age."

"The Morphail Effect," he said. "You can't stay in the past once you have visited the future. Well, not often. And not for long. I don't know why. Neither does Morphail. Reconcile yourself, Mrs. Amelia Underwood, to the knowledge that you must spend eternity here (such as it is). Spend it with me!"

"Mr. Carnelian. No more!"

He slouched to the far side of the footplate.

"I agree to accompany you, to spend my time with you, because I felt it was my duty to try to imbue in you some vestige of a moral education. I shall continue in that attempt. However, if, after a while, it seems to me that there is no hope for you, I shall give up. Then I shall refuse to see you for any reason, whether you keep me prisoner or not!"

He sighed. "Very well, Mrs. Amelia Underwood. But months ago you promised to explain what Virtue was and how I might pursue it. You have still not managed a satisfactory explanation."

"Nil desperandum," she said. Her back grew imperceptibly straighter. "Now…"

And she told him the story of Sir Parsifal as the gold, ebony and ruby locomotive puffed across the sky, trailing glorious clouds of blue and silver smoke behind it.

And so the time went by, until both Mrs. Amelia Underwood and Jherek Carnelian had become thoroughly used to each other's company. It was almost as if they were married (save for one thing — and that did not seem as important as it had, for Jherek was, like all his people, extremely adaptable) and on terms of friendly equality, at that. Even Mrs. Amelia Underwood had to admit there were some advantages to her situation.

She had few responsibilities (save her self-appointed responsibility concerning Jherek's moral improvement) and no household duties. She did not need to hold her tongue when she felt like making an astute observation. Jherek certainly did not demand the attention and respect which Mr. Underwood had demanded when they had lived together in Bromley. And there had been moments in Mrs. Underwood's life in this disgusting and decadent age when she had, for the first time ever, sensed what freedom might mean. Freedom from fear, from care, from the harsher emotions. And Jherek was kind. There was no doubting his enormous willingness to please her, his genuine liking for her character as well as her beauty. She wished that things had been different, sometimes, and that she really was a widow. Or, at least, single. Or single and in her own time where she and Jherek might be married in a proper church by a proper priest. When these thoughts came she drove them away firmly.

It was her duty to remember that one day she might have the opportunity of returning to 23 Collins Avenue, Bromley, preferably in the spring of 1896. Preferably on the night of April 4 at three o'clock in the morning (more or less the time she had been abducted) so that then no one might have to wonder what had happened. She was sensible enough to know that no one would believe the truth and that the speculation would be at once more mundane and more lurid than the actuality. That aspect of her return was not, in fact, very attractive.

None the less, duty was duty.

It was often hard for her to remember what duty actually was in this — this rotting paradise. It was hard, indeed, to cling to all one's proper moral ideals when there was so little evidence of Satan here — no war, no disease, no sadness (unless it was desired), no death, even. Yet Satan must be present. And was, of course, she recalled, in the sexual behaviour of these people. But somehow that did not shock her as much as it had, though it was evidence of the most dreadful decadence. Still, no worse, really than those innocent children, natives of Pawtow Island in the South Seas, where she had spent two years as her father's assistant after Mother had died. They had had no conception of sin, either.

An intelligent, if conventional, woman, Mrs. Amelia Underwood sometimes wondered momentarily if she were doing the right thing in teaching Mr. Jherek Carnelian the meaning of virtue.

Not, of course, that he showed any particular alacrity in absorbing her lessons. She did, on occasions, feel tempted to give the whole thing up and merely enjoy herself (within reason) as she might upon a holiday. Perhaps that was what this age represented — a holiday for the human race after millennia of struggle? It was a pleasant thought. And Mr. Carnelian had been right in one thing — all her friends, her relatives and, naturally, Mr. Underwood, her whole society, the British Empire itself (unbelievable thought that was!) were not only dead a million years, crumbled to dust, they were forgotten . Even Mr. Carnelian had to piece together what he knew of her world from a few surviving records, references by other, later, ages to the 19th century. And Mr. Carnelian was regarded as the planet's greatest specialist in the 19th century. This depressed her. It made her desperate. The desperation made her defiant. The defiance led her to reject certain values which had once seemed to her to be immutable and built solidly into her character. These feelings, luckily, came mainly at night when she was in her own bed and Mr. Carnelian was elsewhere.

And sometimes, when she was tempted to leave the sanctuary of her bed, she would sing a hymn until she fell asleep.

Jherek Carnelian would often hear Mrs. Amelia Underwood singing at night (he had taken to keeping the same hours as the object of his love) and would wake up in some alarm. The alarm would turn to speculation. He would have liked to have believed that Mrs. Underwood was calling to him; some ancient love song like that of the Factory Siren who had once lured men to slavery in the plastic mines. Unfortunately the tunes and the words were more than familiar to him and he associated them with the very antithesis of sexual joy. He would sigh and try, without much success, to go back to sleep as her high, sweet voice sang "Jesus bids us shine with a pure, clear light…" over and over again.
