Take the dictaphone - it has been a complete washout at the Yard.” He talked on, while the luncheon progressed. Finally he turned to Chan. “And what have your methods gained you, Sergeant? You have been successful, I hear.”

Chan shrugged. “Luck - always happy luck.”

“You’re too modest,” said Rankin. “That won’t get you anywhere.”

“The question now arises - where do I want to go?”

“But surely you’re ambitious?” Miss Morrow suggested.

Chan turned to her gravely. “Coarse food to eat, water to drink, and the bended arm for a pillow - that is an old definition of happiness in my country. What is ambition? A canker that eats at the heart of the white man, denying him the joys of contentment. Is it also attacking the heart of white woman? I hope not.” The girl looked away. “I fear I am victim of crude philosophy from Orient. Man - what is he? Merely one link in a great chain binding the past with the future. All times I remember I am link. Unsignificant link joining those ancestors whose bones repose on far distant hillsides with the ten children - it may now be eleven - in my house on Punchbowl Hill.”

“A comforting creed,” Barry Kirk commented.

“So, waiting the end, I do my duty as it rises. I tread the path that opens.” He turned to Sir Frederic. “On one point, from my reading, I am curious. In your work at Scotland Yard, you follow only one clue. What you call the essential clue.”

Sir Frederic nodded, “Such is usually our custom. When we fail, our critics ascribe it to that. They say for example, that our obsession over the essential clue is the reason why we never solved the famous Ely Place murder.”

They all sat up with interest. Bill Rankin beamed. Now things were getting somewhere. “I’m afraid we never heard of the Ely Place murder, Sir Frederic,” he hinted.

“I sincerely wish I never had,” the Englishman replied. “It was the first serious case that came to me when I took charge of the C.I.D. over sixteen years ago. I am chagrined to say I have never been able to fathom it.”

He finished his salad, and pushed away the plate. “Since I have gone so far, I perceive I must go farther. Hilary Galt was the senior partner in the firm of Pennock and Galt, solicitors, with offices in Ely Place, Holborn. The business this firm carried on for more than a generation was unique of its kind. Troubled people in the highest ranks of society went to them for shrewd professional advice and Mr. Hilary Galt and his father-in-law, Pennock, who died some twenty years ago, were entrusted with more numerous and romantic secrets than any other firm of solicitors in London. They knew the hidden history of every rascal in Europe, and they rescued many persons from the clutches of blackmailers.
