Mollie continued to rock to and fro.

"But if I were to tell the police I should have to go to court, I suppose?"

"I suppose so," replied Margaret. "I am afraid I am dreadfully ignorant of such matters. It might depend upon whether you spoke to a high official or to a subordinate one; an ordinary policeman for instance. But the Home office agent has nothing whatever to do with Scotland Yard."

Mollie stood up in order to reach an ash-tray, and: "I really don't think I have anything to say, Miss Halley," she declared. "I have certainly met Mrs. Sin, but I know nothing whatever about her, except that I believe she is a Jewess."

Margaret sighed, looking up wistfully into Mollie's face. "Are you quite sure?" she pleaded. "Oh, Miss Gretna, if you know anything-anything-don't hide it now. It may mean so much."

"Oh, I quite understand that," cried Mollie. "My heart simply aches and aches when I think of poor, sweet little Rita. But-really I don't think I can be of the least tiny bit of use."

Their glances met, and Margaret read hostility in the shallow eyes. Mollie, who had been wavering, now for some reason had become confirmed in her original determination to remain silent. Margaret stood up.

"It is no good, then," she said. "We must hope that Rita will be traced by the police. Good-bye, Miss Gretna. I am so sorry you cannot help."

"And so am I!" declared Mollie. "It is perfectly sweet of you to take such an interest, and I feel a positive worm. But what can I do?"

As Margaret was stepping into her little runabout car, which awaited her at the door, a theory presented itself to account for Mollie's sudden hostility. It had developed, apparently, as a result of Margaret's reference to the Home office inquiry. Of course! Mollie would naturally be antagonistic to a commission appointed to suppress the drug traffic.

Convinced that this was the correct explanation, Margaret drove away, reflecting bitterly that she had been guilty of a strategical error which it was now too late to rectify.

In common with others, Kerry among them, who had come in contact with that perverted intelligence, she misjudged Mollie's motives. In the first place, the latter had no wish to avoid publicity, and in the second place-although she sometimes wondered vaguely what she should do when her stock of drugs became exhausted-Mollie was prompted by no particular animosity toward the Home office inquiry. She had merely perceived a suitable opportunity to make the acquaintance of the fierce red Chief Inspector, and at the same time to secure notoriety for herself.

Ere Margaret's car had progressed a hundred yards from the door, Mollie was at the telephone.

"City 400, please," she said.

An interval elapsed, then: "Is that the Commissioner's office, New Scotland Yard?" she asked.

A voice replied that it was.

"Could you put me through to Chief Inspector Kerry?"

"What name?" inquired the voice.

Mollie hesitated for three seconds, and then gave her family name.

"Very well, madam," said the voice respectfully. "Please hold on, and I will enquire if the Chief Inspector is here."

Mollie's heart was beating rapidly with pleasurable excitement, and she was as confused as a maiden at her first rendezvous. Then: "h.e.l.lo," said the voice.

"Yes?"

"I am sorry, madam. But Chief Inspector Kerry is off duty."

"Oh, dear!" sighed Mollie, "what a pity. Can you tell me where I could find him?"

"I am afraid not, madam. It is against the rules to give private addresses of members of any department."

"Oh, very well." She sighed again. "Thank you."

She replaced the receiver and stood biting her finger thoughtfully. She was making a mental inventory of her many admirers and wondering which of them could help her. Suddenly she came to a decision on the point. Taking up the receiver: "Victoria 8440, please," she said.

Still biting one finger she waited, until: "Foreign office," announced a voice.

"Please put me through to Mr. Archie Boden-Shaw," she said.

Ere long that official's secretary was inquiring her name, and a moment later: "Is that you, Archie?" said Mollie. "Yes! Mollie speaking. No, please listen, Archie! You can get to know everything at the Foreign office, and I want you to find out for me the private address of Chief Inspector Kerry, who is in charge of the Bond Street murder case. Don't be silly! I've asked Scotland Yard, but they won't tell me. You can find out.... It doesn't matter why I want to know.... Just ring me up and tell me. I must know in half an hour. Yes, I shall be seeing you tonight. Good-bye...."

Less than half an hour later, the obedient Archie rang up, and Mollie, all excitement, wrote the following address in a dainty scented notebook which she carried in her handbag.

CHIEF INSPECTOR KERRY, 67 Spenser Road, Brixton.

CHAPTER XXVII. CROWN EVIDENCE

The appearance of the violet-enamelled motor brougham upholstered in cream, and driven by a chauffeur in a violet and cream livery, created some slight sensation in Spenser Road, S.E. Mollie Gretna's conspicuous car was familiar enough to residents in the West End of London, but to lower middle-cla.s.s suburbia it came as something of a shock. More than one window curtain moved suspiciously, suggesting a hidden but watchful presence, when the glittering vehicle stopped before the gate of number 67; and the lady at number 68 seized an evidently rare opportunity to come out and polish her letter-box.

She was rewarded by an un.o.bstructed view of the smartest woman in London (thus spake society paragraphers) and of the most expensive set of furs in Europe, also of a perfectly gowned slim figure. Of Mollie's disdainful face, with its slightly uptilted nose, she had no more than a glimpse.

A neat maid, evidently Scotch, admitted the dazzling visitor to number 67; and Spenser Road waited and wondered. It was something to do with the Bond Street murder! Small girls appeared from doorways suddenly opened and darted off to advise less-watchful neighbors.

Kerry, who had been at work until close upon dawn in the mysterious underworld of Soho was sleeping, but Mrs. Kerry received Mollie in a formal little drawing-room, which, unlike the cosy, homely dining-room, possessed that frigid atmosphere which belongs to uninhabited apartments. In a rather handsome cabinet were a number of trophies a.s.sociated with the detective's successful cases. The cabinet itself was a present from a Regent Street firm for whom Kerry had recovered valuable property.

Mary Kerry, dressed in a plain blouse and skirt, exhibited no trace of nervousness in the presence of her aristocratic and fashionable caller. Indeed, Mollie afterwards declared that "she was quite a ladylike person. But rather tin tabernacley, my dear."

"Did ye wish to see Chief Inspector Kerry parteecularly?" asked Mary, watching her visitor with calm, observant eyes.

"Oh, most particularly!" cried Mollie, in a flutter of excitement. "Of course I don't know what you must think of me for calling at such a preposterous hour, but there are some things that simply can't wait."

"Aye," murmured Mrs. Kerry. "'Twill be yon Bond Street affair?"

"Oh, yes, it is, Mrs. Kerry. Doesn't the very name of Bond Street turn your blood cold? I am simply shivering with fear!"

"As the wife of a Chief Inspector I am maybe more used to tragedies than yoursel', madam. But it surely is a sair grim business. My husband is resting now. He was hard at work a' the night. Nae doubt ye'll be wishin' tee see him privately?"

"Oh, if you please. I am so sorry to disturb him. I can imagine that he must be literally exhausted after spending a whole night among dreadful people."

Mary Kerry stood up.

"If ye'll excuse me for a moment I'll awaken him," she said. "Our household is sma'."

"Oh, of course! I quite understand, Mrs. Kerry! So sorry. But so good of you."

"Might I offer ye a gla.s.s o' sherry an' a biscuit?"

"I simply couldn't dream of troubling you! Please don't suggest such a thing. I feel covered with guilt already. Many thanks nevertheless."

Mary Kerry withdrew, leaving Mollie alone. As soon as the door closed Mollie stood up and began to inspect the trophies in the cabinet. She was far too restless and excited to remain sitting down. She looked at the presentation clock on the mantelpiece and puzzled over the signatures engraved upon a large silver dish which commemorated the joy displayed by the Criminal Investigation Department upon the occasion of Kerry's promotion to the post of Chief Inspector.

The door opened and Kerry came in. He had arisen and completed his toilet in several seconds less than five minutes. But his spotlessly neat attire would have survived inspection by the most lynx-eyed martinet in the Brigade of Guards. As he smiled at his visitor with fierce geniality, Mollie blushed like a young girl.

Chief Inspector Kerry was a much bigger man than she had believed him to be. The impression left upon her memory by his brief appearance at the night club had been that of a small, dapper figure. Now, as he stood in the little drawing-room, she saw that he was not much if anything below the average height of Englishmen, and that he possessed wonderfully broad shoulders. In fact, Kerry was deceptive. His compact neatness and the smallness of his feet and hands, together with those swift, lithe movements which commonly belong to men of light physique, curiously combined to deceive the beholder, but masked eleven stones (*note: 1 stone = 14 pounds) of bone and muscle.

"Very good of you to offer information, miss," he said. "I'm willing to admit that I can do with it."

He opened a bureau and took out a writing-block and a fountain pen. Then he turned and stared hard at Mollie. She quickly lowered her eyes.

"Excuse me," said Kerry, "but didn't I see you somewhere last night?"

"Yes," she said. "I was sitting just inside the door at-"

"Right! I remember," interrupted Kerry. He continued to stare. "Before you say any more, miss, I have to remind you that I am a police officer, and that you may be called upon to swear to the truth of any information you may give me."

"Oh, of course! I know."

"You know? Very well, then; we can get on. Who gave you my address?"

At the question, so abruptly asked, Mollie felt herself blushing again. It was delightful to know that she could still blush. "Oh-I... that is, I asked Scotland Yard "

She bestowed a swift, half-veiled glance at her interrogator, but he offered her no help, and: "They wouldn't tell me," she continued. "So-I had to find out. You see, I heard you were trying to get information which I thought perhaps I could give."

"So you went to the trouble to find my private address rather than to the nearest police station," said Kerry. "Might I ask you from whom you heard that I wanted this information?"

"Well-it's in the papers, isn't it?"

"It is certainly. But it occurred to me that someone... connected might have told you as well."

"Actually, someone did: Miss Margaret Halley."

"Good!" rapped Kerry. "Now we're coming to it. She told you to come to me?"

"Oh, no!" cried Mollie-"she didn't. She told me to tell her so that she could tell the Home office."

"Eh?" said Kerry, "eh?" He bent forward, staring fiercely. "Please tell me exactly what Miss Halley wanted to know."

The intensity of his gaze Mollie found very perturbing, but: "She wanted me to tell her where Mrs. Sin lived," she replied.

Kerry experienced a quickening of the pulse. In the failure of the C.I.D. to trace the abode of the notorious Mrs. Sin he had suspected double-dealing. He counted it unbelievable that a figure so conspicuous in certain circles could evade official quest even for forty-eight hours. K Division's explanation, too, that there were no less than eighty Chinamen resident in and about Limehouse whose names either began or ended with Sin, he looked upon as a paltry evasion. That very morning he had awakened from a species of nightmare wherein 719 had affected the arrest of Kazmah and Mrs. Sin and had rescued Mrs. Irvin from the clutches of the former. Now-here was hope. 719 would seem to be as hopelessly in the dark as everybody else.

"You refused?" he rapped.

"Of course I did, Inspector," said Mollie, with a timid, tender glance. "I thought you were the proper person to tell."

"Then you know?" asked Kerry, unable to conceal his eagerness.

"Yes," sighed Mollie. "Unfortunately-I know. Oh Inspector, how can I explain it to you?"

"Don't trouble, miss. Just give me the address and I'll ask no questions!"

His keenness was thrilling, infectious. As a result of the night's "beating" he had a list of some twenty names whose owners might have been patrons of Kazmah and some of whom might know Mrs. Sin. But he had learned from bitter experience how difficult it was to induce such people to give useful evidence. There was practically no means of forcing them to speak if they chose, from selfish motives, to be silent. They could be forced to appear in court, but anything elicited in public was worse than useless. Furthermore, Kerry could not afford to wait. Mollie replied excitedly: "Oh, Inspector, I know you will think me simply an appalling person when I tell you; but I have been to Mrs. Sin's house-'The House of a Hundred Raptures' she calls it-"

"Yes, yes! But-the address?"

"However can I tell you the address, Inspector? I could drive you there, but I haven't the very haziest idea of the name of the horrible street! One drives along dreadful roads where there are stalls and Jews for quite an interminable time, and then over a sort of ca.n.a.l, and then round to the right all among ships and horrid Chinamen. Then, there is a doorway in a little court, and Mrs. Sin's husband sits inside a smelly room with a positively ferocious raven who shrieks about legs and policemen! Oh! Can I ever forget it!"

"One moment, miss, one moment," said Kerry, keeping an iron control upon himself. "What is the name of Mrs. Sin's husband?"

"Oh, let me think! I can always remember it by recalling the croak of the raven." She raised one hand to her brow, posing reflectively, and began to murmur: "Sin Sin Ah... Sin Sin Jar... Sin Sin-Oh! I have it! Sin Sin Wa!"

"Good!" rapped Kerry, and made a note on the block. "Sin Sin Wa, and he has a pet raven, you say, who talks?"

"Who positively talks like some horrid old woman!" cried Mollie. "He has only one eye."

"The raven?"

"The raven, yes-and also the Chinaman."

"What!"

"Oh! it's a nightmare to behold them together!" declared Mollie, clasping her hands and bending forward.

She was gaining courage, and now looked almost boldly into the fierce eyes of the Chief Inspector.

"Describe the house," he said succinctly. "Take your time and use your own words."

Thereupon Mollie launched into a description of Sin Sin Wa's opium-house. Kerry, his eyes fixed upon her face, listened silently. Then: "These little rooms are really next door?" he asked.

"I suppose so, Inspector. We always went through the back of a cupboard!"

"Can you give me names of others who used this place?"

"Well"-Mollie hesitated-"poor Rita, of course and Sir Lucien. Then, Cyrus Kilfane used to go."

"Kilfane? The American actor?"

"Yes."

"H'm. He's back in America, Sir Lucien is dead, and Mrs. Irvin is missing. n.o.body else?"
