“I agree,” said Holmes.

Lofte waited for us to explain, and when we did not, he went on.

“He hired a small space on the fringes of the city's International Settlement, and began to hold services, a mixture of the familiar and the exotic, from Jesus as guru to the health benefits of Yoga. Mind-reading, I understand, was a regular feature. He claimed to have received personal messages from the shade of Madame Blavatsky, the Theosophist. Before long, he bought the building outright, thanks to the bored and wealthy wives and daughters of the English-speaking community, who just lapped him up.”

“Mixing Hinduism, Yoga, mysticism, that sort of thing?”

“And Tantra,” he added, then quickly moved on before I could ask for details-but I had no need to ask. Tantra employed sexuality as a means to mystic union: a true discipline in its original home, a means of exploitation by unscrupulous charlatans in the West. I should not be surprised to find among its devotees a man who would marry a child he thought to be sixteen.

Lofte dipped back into the envelope for another sheet. He handed it to Mycroft, who read it then laid it atop the first. “They were divorced in 1920. She cited abandonment for her and their child.”

Holmes cleared his throat. “Child?”

“Yes. According to a woman who had remained friends with Yolanda after she left the-the pleasure house, she had a child in 1913.” He went back to his envelope, this time for a telegraph flimsy. “I had to leave a number of elements in this investigation to others, you understand, since time was a priority. This was waiting for me in Cairo.”

Holmes, reading this, made a tiny noise that might have been a sigh, or a whimper.

Lofte continued. “It would appear that she and Hayden did not live together, as he had a house in the International Settlement, where Chinese were not made welcome. Certainly they were separated by March 1917, when she began work as a barmaid two streets down from the… house where she had lived. There is, I will mention, no evidence of a child during this time. Giving a child over to one's grandparents to be raised is a common practise for… among girls who live in the city.

“Then in 1920, Damian Adler arrived in Shanghai. As I said, he found rooms in-I shouldn't perhaps call it a house, it is a compound of many dwellings, an arrangement that fosters close, almost familial ties-the girls who were there at the time remember Mr Adler with respect and affection. He went through periods of heavy drinking, and was arrested twice in the waning months of 1920.”

By now, Holmes did not even blink.

“The first arrest was for being so drunk the wagon that picked him up thought he was dead.”

“Well,” I murmured, “he only claimed that he was free from drugs use.”

Holmes paid my comment no mind. “And the second?”

“Ah, well, that was a month later, and more serious. Mr Adler was in a brawl in November 1920, and beat a man up. He was arrested, but when the man came out of hospital three days later, he refused to press charges. Adler was let go with a warning.”

Lofte was watching Holmes in a manner that suggested anticipation. Holmes studied him, then obediently asked, “Do we know who the victim was?”

A tiny smile flickered over the Swiss man's mouth, and he went back to his envelope. This time the document was two pieces of paper pinned together in the corner; it took Mycroft a full minute to read and pass on this one, a police report recording the injuries of one John Haycock: Concussion, broken collar bone, cracked humerus, contusions, broken tooth-fairly standard stuff for a bar brawl. Holmes flipped over to the second page, and there was a photograph of our human punching bag, his features so swollen and bruised, his mother would not have known him.

“John Haycock, eh?” Holmes mused.

“The address he gave the hospital was false,” Lofte said.

The man's hair was dark, but there was no telling if he had a scar beside his eye.

Holmes was studying the photograph, then shook his head. “It's a pity-”

He stopped, his eyes darting to Lofte's fingers on the near-flat envelope. “You don't?”

In answer, the man in the worn suit drew out a glossy photograph and half-stood to lay it with great deliberation on the table before Holmes. He sat back, on his face a look of tired contentment. “This was put into my hands by a reporter of one of the Shanghai dailies, ninety-five minutes before-” He shot a glance at Mycroft. “Shall we say, I happened to know that a military 'plane was about to leave, and I thought that might be my best chance to get this photograph to London.”

“What day was this?” I asked. Mycroft had wired his request for information ten days earlier; Lofte must have assembled all this information in a matter of hours.

“Sunday.”

Two of us frankly stared at him; Mycroft studied his glass, but one side of his mouth had a small curl of satisfaction.

“Six days to cross two entire continents?” I marvelled. “Impossible!”

“Not if one is given carte blanche with requisitioning aeroplanes and rescheduling trains. I employed nine aeroplanes, three trains, eighteen motor-cars, two motor-cycles, one bicycle, and a rickshaw.”

Mycroft spoke up. “My department has an ongoing interest in what one might call practical experiments in rapid travel. Mr Lofte now holds the record.”

“Won a tenner, too,” our Twentieth-Century Mercury murmured. “ Harrison bet me I couldn't do it in under eight days. My partner in Shanghai,” he explained.

Holmes resumed the photograph, tilting it for me when I looked over his arm.

“My reporter friend became interested in Hayden a year ago when he heard a rumour that the good Reverend was quietly selling up church holdings-several buildings, in good parts of town, a lot of stocks and valuables that members had donated for charitable works which somehow didn't come to fruition. There were also rumours of darker doings, several deaths among his congregation. The photo was taken the tenth of September last year; the next day, the Reverend was on a boat for England. The reporter reckons various officials were paid off, not to notice. Hayden won't be prosecuted, but on the other hand, he won't be welcomed back.”

Hayden's image was quite clear, despite having been taken across a busy street. The man, strong in body and haughty in manner, was dressed in a beautifully cut summer-weight suit and a shirt with an ordinary soft collar and neck-tie. He had his straw hat in his hand as he prepared to climb into a car waiting at the kerb. Something must have caught his attention, because he was turned slightly, face-on to the camera. He looked vaguely familiar, although I had only seen the back of his head, so far as I knew. His eyes were dark and compelling, his mouth full, his hair sleek and black. And his left eye was elongated by a stripe of darker skin, a scar like the tail of a comet. Like the reappearing shape of the Children of Lights.

Holmes passed it over to Mycroft. “We need copies.”

“Certainly. Lofte, did you have anything else for us?”

“A few clippings about the church, but that's it.”

I shifted, and three pairs of eyes turned to me. Not that I wished to be greedy, however: “The Adlers have a child. Estelle. Did you come upon any birth record for her?”

Lofte's tired face sagged with remorse. “I was told to investigate the background of Damian Adler's wife, Yolanda, at all haste. I interpreted that to mean her background before their marriage. I did not pursue copies of their marriage certificate, or their current bank accounts, or the child's papers. I can get that information in a day, if you need it.”

“The only urgent piece of information we need is, did she have another child, after Dorothy Hayden in 1913 but before she married Damian?”
