"His daughter! I never knew he had one."

"No; perhaps not. He doesn't often speak of her, I believe. I saw her once, not long ago."

"They have quarrelled--father and daughter!" exclaimed Rolfe. "And that accounts for her exposure of the plot against Statham to compel him to commit suicide rather than to face exposure. Remember, she would not betray who was Adam's a.s.sociate in the matter. Because it is her own father, without a doubt."

"She alleged that Statham committed a secret crime, by which he laid the foundation of his great fortune," Max remembered. "And, further, that confirmation of the charge brought by Adam will be found beyond that locked door?"

"Yes," said his companion, in a hollow voice; "I see it all. The girl wishes to exclude her father from the business. Yet she knows more than she has told me."

"No doubt. She probably knew Maud also, for she has lived for years-- indeed, nearly all her life--in Belgrade," Barclay remarked. "She quarrelled with her father, and went on the stage as a dancer in the Opera at Vienna. She is now in Paris in the same capacity. If I remember aright she was here at Covent Garden last season. They say she has great talent and that she's now being trained in Paris for the part of _premiere danseuse_."

"She alleged that there still live two witnesses of Statham's crime, whatever it was," Charlie went on.

"And they are probably Adam and her hunchback father--both men who have lived the life of the wilds beyond the fringe of civilisation--both men who are as unscrupulous as they are adventurous."

"But from all I knew of Lyle he was a most highly respectable person.

In Belgrade they still speak of him with greatest respect."

"Leonard Lyle in Belgrade, my dear chap, may have been a very different person to Leonard Lyle in other countries, you know," was his friend's reply.

"But why has his daughter given me this warning, at the same time taking care to conceal her ident.i.ty."

"She was a short, dark-haired girl, rather good-looking, except that her top teeth protruded a little; about nineteen or so--eh?"

"Exactly."

"And depend upon it that she has warned you at Maud's request, in order that you may be forearmed against the blow which the pair are going to strike."

"And which we--you and I, Max--are going to a.s.sist--eh?" added the other, grimly.

CHAPTER FORTY SIX.

TO LEARN THE TRUTH.

The mystery by which old Sam Statham sometimes pa.s.sed beyond that white-enamelled door was inexplicable.

Whenever he left the library to ascend the stairs, Charlie Rolfe stole quietly out behind him, and listened. Sometimes he distinctly heard the key in the lock; at others it sounded as though the closed door yielded to his touch and swung aside for him to pa.s.s beyond. It closed always with a thud, as though felt had been placed upon it to prevent any metallic clang.

While Charlie watched the great financier's every movement, Max was unceasing in his inquiries regarding Marion. Advertis.e.m.e.nts had Men published in the "personal" columns of various newspapers, and the private inquiry agents whose aid he had sought had been unremitting in their vigilance.

The whole affair from beginning to end now showed the existence of some powerful hand which had directed and rendered the mystery beyond solution. The strange re-appearance of Jean Adam and Leonard Lyle had been followed quickly by the extraordinary flight of Doctor Petrovitch and Maud. The latter had only an hour before she had disappeared into s.p.a.ce made some remarkable confession to Marion--a confession which might or might not save Samuel Statham from an ignominious death.

But the girl had preserved the secret of the confession confided to her by her friend, and, preferring shame and misjudgment, she in turn had disappeared, whither no one knew.

The two men, brother and lover, who had now united their forces to solve the problem and at the same time ascertain for themselves what the secret of the house in Park Lane really was, were at their wits' ends.

Their inquiries and their efforts always led them into a _cul-de-sac_.

At every turn they seemed foiled and baffled. And was it surprising when it was considered the power of Samuel Statham and the means at his command for the preservation of a secret?

Charlie felt that he was being watched hourly by one or other of those spies who sometimes gave such valuable information to the head of the firm. Some of these secret agents of Statham he knew by sight, but there were others unseen and unknown.

Even though Max and his friend were able to enter unheard and secrete themselves before the place was locked up by old Levi, yet there was that white door barring their pa.s.sage to the mystery beyond. Many times they discussed the possibilities, and each time hesitated. Charlie was sorely puzzled regarding the key of the iron door. Sometimes it was undoubtedly used, sometimes not.

At last one evening, after both men had dined at the St James's, of which Max was a member, they resolved upon a bold move. Charlie suggested it, and the other was at once ready and eager.

So after Max had been round to his rooms to put on a suit of dark tweeds, he went to Charlie's chambers where the various implements were produced and laid upon the table. It was then nearly ten o'clock.

Rolfe, having sent Green to the other end of Jermyn Street out of the way, drew out the whisky decanter from the tantalus stand, poured out two "pegs" with soda, and drank:

"Success to the elucidation of old Statham's secret."

Then, carefully stowing the various articles in their pockets, they slipped down into the street and were out of sight before the inquisitive Green had returned.

Arrived in Park Lane, after a hasty walk, they strolled slowly along by the park railings past the house. All was in darkness save the hall, where the electric lamp showed above the fanlight. Old Sam was probably in his study, smoking his last cigar, for the shutters were that night closed, as they sometimes were. The shutters of the bas.e.m.e.nt were also closed behind their iron bars, while at the upstairs windows all the blinds were carefully drawn.

Indeed, the exterior of the house presented nothing unusual. It was the same as any other mansion in Park Lane. Yet there were many who on going up and down the thoroughfare afoot or on the motor-'buses jerked their thumbs at it and whispered. The house had earned a reputation for mystery. Sam Statham was a mystery in himself, and of his house many weird things were alleged.

Thrice the pair pa.s.sed and repa.s.sed. At the corner of Deanery Street stood a constable, and while he remained there it was injudicious to attempt an entry with a latchkey. So they strolled back in the direction of the fountain, conversing in undertones.

Max glanced at his watch, and found that it wanted a quarter to eleven.

At last they crossed the road and pa.s.sed the door. All seemed quiet.

At that moment the only object in sight was a receding motor-'bus showing its red tail-light. Not a soul was on the pavement.

"All clear!" cried Charlie, scarce above a whisper, as he slipped up the two or three steps, followed by his companion.

That moment was an exciting one. Next second, however, the key was in the latch, and without a sound the wards of the lock were lifted.

In another moment the pair stood within the brightly-lit hall, and the door was closed noiselessly behind them.

Standing there, within a few yards of the door of the library, where from the smell of tobacco smoke it was evident that old Sam was taking his ease, they were in imminent risk of discovery. Besides, Levi had a habit of moving without sound in his old felt slippers, and might at any moment appear up the stairs from the lower regions.

Instinctively Charlie glanced upstairs towards the locked door. But next second he motioned his companion to follow, and stole on tiptoe over the thick Turkey carpets past the millionaire's door and on into a kind of small conservatory which lay behind the hall and was in darkness.

Though leading from the room behind the library, it was a fairly good spot as a place of hiding, yet so vigilant was old Levi that the chances were he would come in there poking about ere he retired to rest.

The two men stood together behind a bank of what had once been greenhouse plants, but all of them had died by neglect and want of water long ago. The range of pots and dried stalks still remained, forming an effectual barrier behind which they could conceal themselves.

Through the long French window of the room adjoining the light shone, and Charlie, slowly creeping forward, peered within.

Then he whispered to his friend, and both men bent to see what was transpiring.

The scene was unusual.

A full view of the library could be obtained from where they stood in the darkness. In the room two of the big armchairs had been pulled up, with a small coffee table between them. On one side was old Sam, lazily smoking one of his big cigars, while on the other was Levi, lying back, his legs stretched out, smoking with perfect equanimity and equally with his master. Upon the table was a decanter of whisky and two gla.s.ses, and, judging from the amused countenances of both men, Sam had been relating to Levi something which struck the other as humorous.

It was curious, to say the least, that Levi, the humble, even cringing, servant should place himself upon an equality with his master. That he was devoted to old Sam, Charlie knew well, but this friendship he had never suspected. There was a hidden reason for it all, without a doubt.

The two intruders watched with bated breath, neither daring to make a sound.

They saw Levi, his cigar stuck in the side of his mouth, lean back and thrust his hands deep into his trousers-pockets, uttering some words which they could not catch. His manner had changed, and so had Sam's.
