She heard the "click" of his receiver and replaced her own slowly. She did not attempt to go back to the outer office, but waited by the closed door. She recalled the night, the terror of that unknown presence in her darkened flat, and shuddered. Then Beale, surprisingly sober, had come in and he and the "burglar" had gone away together.

What had these two, Mr. Beale and the "Herr Professor," in common? She heard the snap of the outer door, and Beale's voice speaking quickly. It was probably German--she had never acquired the language and hardly recognized it, though the guttural "Zu befel, Herr Peale" was distinct.

She heard the shuffle of the man's feet and the closing of the outer door and then Beale came in, and his face was troubled.

"I can't tell you how sorry I am that the old man called--I'd forgotten that he was likely to come."

She leant against the table, both hands behind her.

"Mr. Beale," she said, "will you give me straightforward answers to a number of plain questions?"

He nodded.

"If I can," he said.

"Is the Herr Professor a friend of yours?"

"No--I know him and in a way I am sorry for him. He is a German who pretends to be Russian. Immensely poor and unprepossessing to a painful degree, but a very clever scientist. In fact, a truly great analytical chemist who ought to be holding a good position. He told me that he had the best qualifications, and I quite believe him, but that his physical infirmities, his very freakishness had ruined him."

Her eyes softened with pity--the pity of the strong for the weak, of the beautiful for the hideous.

"If that is true----" she began, and his chin went up. "I beg your pardon, I know it is true. It is tragic, but--did you know him before you met him in my room?"

He hesitated.

"I knew him both by repute and by sight," he said. "I knew the work he was engaged on and I guessed why he was engaged. But I had never spoken to him."

"Thank you--now for question number two. You needn't answer unless you wish."

"I shan't," he said.

"That's frank, anyway. Now tell me, Mr. Beale, what is all this mystery about? What is the Green Rust? Why do you pretend to be a--a drunkard when you're not one?" (It needed some boldness to say this, and she flushed with the effort to shape the sentence.) "Why are you always around so providentially when you're needed, and," here she smiled (as he thought) deliciously, "why weren't you round yesterday, when I was nearly arrested for theft?"

He was back on the edge of the table, evidently his favourite resting-place, she thought, and he ticked her questions off on his fingers.

"Question number one cannot be answered. Question number two, why do I pretend to be a--a drunkard?" he mimicked her audaciously. "There are other things which intoxicate a man beside love and beer, Miss Cresswell."

"How gross!" she protested. "What are they?"

"Work, the chase, scientific research and the first spring scent of the hawthorn," he said solemnly. "As to the third question, why was I not around when you were nearly arrested? Well, I was around. I was in your flat when you came in and escaped along the fire parapet."

"Mr. Beale!" she gasped. "Then it was you--you are a detective!"

"I turned your desk and dressing-chest upside down? Yes, it was I," he said without shame, ignoring the latter part of the sentence. "I was looking for something."

"You were looking for something?" she repeated. "What were you looking for?"

"Three registered envelopes which were planted in your flat yesterday morning," he said, "and what's more I found 'em!"

She put her hand to her forehead in bewilderment.

"Then you----"

"Saved you from a cold, cold prison cell. Have you had any lunch? Why, you're starving!"

"But----"

"Bread and butter is what you want," said the practical Mr. Beale, "with a large crisp slice of chicken and stacks of various vegetables."

And he hustled her from the office.

CHAPTER VI

MR. SCOBBS OF RED HORSE VALLEY

Mr. White, managing director of Punsonby's Store, was a man of simple tastes. He had a horror of extravagance and it was his boast that he had never ridden in a taxi-cab save as the guest of some other person who paid. He travelled by tube or omnibus from the Bayswater Road, where he lived what he described as his private life. He lunched in the staff dining-room, punctiliously paying his bill; he dined at home in solitary state, for he had neither chick nor child, heir or wife. Once an elder sister had lived with him and had died (according to the popularly accepted idea) of slow starvation, for he was a frugal man.

It seems the fate of apparently rich and frugal men that they either die and leave their hoardings to the State or else they disappear, leaving behind them monumental debts. The latter have apparently no vices; even the harassed accountant who disentangles their estates cannot discover the channel through which their hundreds of thousands have poured. The money has gone and, if astute detectives bring back the defaulter from the pleasant life which the Southern American cities offer to rich idlers, he is hopelessly vague as to the method by which it went.

Mr. Lassimus White was the managing director and general manager of Punsonby's. He held, or was supposed to hold, a third of the shares in that concern, shares which he had inherited from John Punsonby, his uncle, and the founder of the firm. He drew a princely salary and a substantial dividend, he was listed as a debenture holder and was accounted a rich man.

But Mr. White was not rich. His salary and his dividends were absorbed by a mysterious agency which called itself the Union Jack Investment and Mortgage Corporation, which paid premiums on Mr. White's heavy life insurance and collected the whole or nearly the whole of his income. His secret, well guarded as it was, need be no secret to the reader. Mr.

White, who had never touched a playing-card in his life and who grew apoplectic at the sin and shame of playing the races, was an inveterate gambler. His passion was for Sunken Treasure Syndicates, formed to recover golden ingots from ships of the Spanish Armada; for companies that set forth to harness the horse-power of the sea to the services of commerce; for optimistic companies that discovered radium mines in the Ural Mountains--anything which promised a steady three hundred per cent.

per annum on an initial investment had an irresistible attraction for Mr. White, who argued that some day something would really fulfil expectations and his losses would be recovered.

In the meantime he was in the hands of Moss Ibramovitch, trading as the Union Jack Investment and Mortgage Corporation, licensed and registered as a moneylender according to law. And being in the hands of this gentleman, was much less satisfactory and infinitely more expensive than being in the hands of the bankruptcy officials.

In the evening of the day Oliva Cresswell had started working for her new employer, Mr. White stalked forth from his gloomy house and his departure was watched by the two tough females who kept house for him, with every pleasure. He strutted eastward swinging his umbrella, his head well back, his eyes half-closed, his massive waistcoat curving regally. His silk hat was pushed back from his forehead and the pince-nez he carried, but so seldom wore, swung from the cord he held before him in that dead-mouse manner which important men affect.

He had often been mistaken for a Fellow of the Royal Society, so learned and detached was his bearing. Yet no speculation upon the origin of species or the function of the nebulae filled his mind.

At a moment of great stress and distraction, Dr. van Heerden had arisen above his horizon, and there was something in Dr. van Heerden's manner which inspired confidence and respect. They had met by accident at a meeting held to liquidate the Shining Strand Alluvial Gold Mining Company--a concern which had started forth in the happiest circumstances to extract the fabulous riches which had been discovered by an American philanthropist (he is now selling Real Estate by correspondence) on a Southern Pacific island.

Van Heerden was not a shareholder, but he was intensely interested in the kind of people who subscribe for shares in Dreamland Gold mines. Mr.

White had attended incognito--his shares were held in the name of his lawyer, who was thinking seriously of building an annex to hold the unprofitable scrip.

Mr. White was gratified to discover a kindred soul who believed in this kind of speculation.

It was to the doctor's apartment that he was now walking. That gentleman met him in the entrance and accompanied him to his room. There was a light in the fanlight of Oliva's flat, for she had brought some of her work home to finish, but Mr. Beale's flat was dark.

This the doctor noted before he closed his own door, and switched on the light.

"Well, White, have you made up your mind?" he demanded without preliminary.

"I--ah--have and I--ah--have not," said the cautious adventurer. "Forty thousand is a lot of money--a fortune, one might say--yes, a fortune."
