The bell rang over the door and a sallow, thin-featured, clean-shaven man dressed in a dark tweed overcoat and howler hat entered the apothecary shop. He smiled at the young woman behind the counter. She was several months pregnant and just beginning to show.
"Good afternoon, sir." Jasmine said.
"Good afternoon, Madame," Grayson said. "I wonder, might I speak with your husband?"
"Certainly, sir," said Jasmine, not thinking that there was anything odd about the man's request. There were many times when gentlemen had problems of a very private nature that they were reluctant to discuss with a woman. "One moment please and I will bring him."
She stepped through the curtains leading to the back rooms and a moment later, a slightly built man with prematurely grey hair came out, wiping his hands on a leather apron. Grayson was surprised to see that he was not an Oriental.
"Yes, sir." said Moreau. "My wife said you wished to see me? How may I assist you?"
Grayson frowned. "Perhaps I have made some sort of mistake." he said. "I was expecting someone else, an older gentleman, a… that is, well… excuse me, you are the proprietor here?"
"Ah." said Moreau, "you must mean my wife's grandfather, Lin Tao. One moment, I will ask him to come in.”
Moreau disappeared behind the curtains and came back a moment later with Lin Tao.
The old man gave him a slight bow. "Good afternoon,” he said. "Excuse me, perhaps my memory fails me. but I do not recall that we have met before."
"No. we have never actually met," said Grayson. "But you might say that our paths have missed on numerous occasions."
He reached into his pocket and took out a length of singed, dark green ribbon. He held it out across the counter to Lin Tao.
"I am Chief Inspector William Grayson of Scotland Yard," he said.
Lin Tao regarded him steadily. "Yes," he said. "I know."
"It took me a very long time to find you." Grayson said, putting the ribbon down on the wooden countertop. "I did not come here in an official capacity I believe I owe you a great debt of gratitude and I have come to thank you. And also to ask a favor, I have had difficulty sleeping these past few months."
"Perhaps a preparation of tincture of opium and belladonna would be the solution to your problem," Lin Tao said.
Grayson smiled. "No, I do not think so. However, I think the answers to some puzzling questions which have kept me up at night for weeks on end might do the trick."
The two men held each other's gaze for a long time. Then the ghost of a smile appeared on Lin Tao's face and he gave a slight nod.
"In that case Inspector Grayson, perhaps you would like to join us for tea?"
