until the door opened and the prisoner was brought in.
One swift glance the Chief Inspector gave at the battle-scarred face, and recognized instantly that this was a badly frightened man. Crossing to the table he took up a typewritten slip which lay there, and:
'Your name is James Poland?' he said. 'Four convictions; one, robbery with violence.'
Jim Poland nodded sullenly.
'You were arrested at the corner of Pekin Street about midnight. What were you doing there?'
'Taking a walk.'
'I'll say it again,' rapped Kerry, fixing his fierce eyes upon the man's face. 'What were you doing there?'
'I've told you.'
'And I tell you you're a liar. Where did you leave the man Cohen?'
Poland blinked his small eyes, cleared his throat, and looked down at the floor uneasily. Then:
'Who's Cohen?' he grunted.
'You mean, who was Cohen?' cried Kerry.
The shot went home. The man clenched his fists and looked about the room from face to face.
'You don't tell me--' he began huskily.
'I've told you,' said Kerry. 'He's on the slab. Spit out the truth; it'll be good for your health.'
The man hesitated, then looked up, his eyes half closed and a cunning expression upon his face.
'Make out your own case,' he said. 'You've got nothing against me.'
Kerry snapped his teeth together viciously.
'I've told you what happened to your pal,' he warned. 'If you're a wise man you'll come in on our side, before the same thing happens to you.'
'I don't know what you're talking about,' growled Poland.
Kerry nodded to the constable at the doorway.
'Take him back,' he ordered.
Jim Poland being returned to his cell, Kerry, as the door closed behind the prisoner and his guard, stared across at Durham where he stood beside the table.
'An old hand,' he said. 'But there's another way.' He glanced at the officer in charge. 'Hold him till the morning. He'll prove useful.'
From his waistcoat pocket he took out a slip of chewing gum, unwrapped it, and placed the mint-flavoured wafer between his large white teeth. He bit upon it savagely, settled his hat upon his head, and, turning, walked toward the door. In the doorway he paused.
'Come with me, Durham,' he said. 'I am leaving the conduct of the case entirely in your hands from now onward.'
Detective Durham looked surprised and not a little anxious.
'I am doing so for two reasons,' continued the Chief Inspector. 'These two reasons I shall now explain.'
III. THE SECRET TREASURE-HOUSE
Unlike its sister colony in New York, there are no show places in Limehouse. The visitor sees nothing but mean streets and dark doorways. The superficial inquirer comes away convinced that the romance of the Asiatic district has no existence outside the imaginations of writers of fiction. Yet here lies a secret quarter, as secret and as strange, in its smaller way, as its parent in China which is called the Purple Forbidden City.
On a morning when mist lay over the Thames reaches, softening the harshness of the dock buildings and lending an air of mystery to the vessels stealing out upon the tide, a man walked briskly along Limehouse Causeway, looking about him inquiringly, as one unfamiliar with the neighbourhood. Presently he seemed to recognize a turning to the right, and he pursued this for a time, now walking more slowly.
A European woman, holding a half-caste baby in her arms, stood in an open doorway, watching him uninterestedly. Otherwise, except for one neatly dressed young Chinaman, who passed him about halfway along the street, there was nothing which could have told the visitor that he had crossed the borderline dividing West from East and was now in an Oriental town.
A very narrow alleyway between two dingy houses proved to be the spot for which he was looking; and, having stared about him for a while, he entered this alleyway. At the farther end it was crossed T-fashion, by another alley, the only object of interest being an iron post at the crossing, and the scenery being made up entirely of hideous brick walls.
About halfway along on the left, set in one of these walls, were strong wooden gates, apparently those of a warehouse. Beside them was a door approached by two very dirty steps. There was a bell- push near the door, but upon neither of these entrances was there any plate to indicate the name of the proprietor of the establishment.
From his pocket-book the visitor extracted a card, consulted something written upon it, and then pressed the bell.
It was very quiet in this dingy little court. No sound of the busy thoroughfares penetrated here; and although the passage forming the top of the 'T' practically marked the river bank, only dimly could one discern the sounds which belong to a seaport.
Presently the door was opened by a Chinese boy who wore the ordinary native working dress, and who regarded the man upon the step with oblique, tired-looking eyes.
'Mr. Huang Chow?' asked the caller.
The boy nodded.
'You wantchee him see?'
'If he is at home.'
The boy glanced at the card, which the visitor still held between finger and thumb, and extended his hand silently. The card was surrendered. It was that of an antique dealer of Dover Street, Piccadilly, and written upon the back was the following: 'Mr. Hampden would like to do business with you.' The signature of the dealer followed.
The boy turned and passed along a dim and perfectly unfurnished passage which the opening of the door had revealed, while Mr. Hampden stood upon the step and lighted a cigarette.
In less than a minute the boy returned and beckoned to him to come in. As he did so, and the door was closed, he almost stumbled, so dark was the passage.
Presently, guided by the boy, he found himself in a very business-like little office, where a girl sat at an American desk, looking up at him inquiringly.
She was of a dark and arresting type. Without being pretty in the European sense, there was something appealing in her fine, dark eyes, and she possessed the inviting smile which is the heritage of Eastern women. Her dress was not unlike that of any other business girl, except that the neck of her blouse was cut very low, a fashion affected by many Eurasians, and she wore a gaily coloured sash, and large and very costly pearl ear-rings. As Mr. Hampden paused in the doorway:
'Good morning,' said the girl, glancing down at the card which lay upon the desk before her. 'You come from Mr. Isaacs, eh?'
She looked at him with a caressing glance from beneath half- lowered lashes, but
