He submitted amiably, the more so since not ill-pleased with himself. And when again they were moving round the floor, she bore more heavily upon his shoulder and was thoughtful longer than he had expected. Then--

"Attention, my friend."

"I am listening, Sophie."

"If what you hint is true--and I do not doubt it is--Karl's day is done."

"More nearly than he dreams," Lanyard affirmed grimly.

"I shan't be sorry. I am German through and through; what I do, I do for the Fatherland, and in that find absolution for many things I care not to remember. If through what you tell me I may prove Karl traitor, I owe you something."

"Always it has been my fondest hope, Sophie, some day to have you in my debt."

Her fingers tightened on his. "Do not jest in the shadow of death. Since you have been unwise enough to venture here to-night, you will not be permitted to leave alive--unless you pledge yourself to us and prove your sincerity by producing that paper."

"That sounds reasonable--like Prussia. What next?"

"I have warned you, so paid off my debt. The rest is your affair."

"Do you imagine I take this seriously?"

"It will turn out seriously for you if you do not."

"How can I be prevented from leaving when I will, from a public restaurant?"

"Is it possible you don't know this place? It is maintained by the Wilhelmstra.s.se. Attempt to leave it without coming to a satisfactory understanding, and see what happens."

"What, for instance?"

"The lights would be out before you were half across the room. When they went up again, the Lone Wolf would be no more, and never a soul here would know who stabbed him or what became of the knife."

"Are you by any chance amusing yourself at my expense?"

Once more the woman showed him her handsome eyes: he found them frankly grave, earnest, unwavering.

"If you will not listen, your blood be on your own head."

"Forgive me. I didn't mean to be rude...."

"Still, you do not believe!"

"You are wrong. I am merely amused."

"If you understood, you could never mock your peril."

"But I don't mock it. I am enchanted with it. I accept it, and it renews my youth. This might be Paris of the days when you ran with the Pack, Sophie--and I alone!"

The woman moved her pretty shoulders impatiently. "I think you are either mad or ... the very soul of courage!"

The encore ended; they returned to the table, Sophie leaning lightly on Lanyard's arm, chattering gay inconsequentialities.

Dropping into her chair, she bent over toward Cecelia Brooke.

"He dances adorably, my dear!" the intrigante declared. "But I dare say you know that already."

The English girl shook her head, smiling. "Not yet."

"Then lose no time. You two should dance well together, for you are more of a size. I think the next number will be a waltz. We get altogether too few of them; these American dances, these one-steps and foxtrots, they are not dances, they are mere romps, favourites none the less. And there is always more room on the floor; so few waltz nowadays. Really, you must not miss this opportunity."

This playful insistence, the light stress she laid upon her suggestion that Cecelia Brooke dance with him, considered in conjunction with her recent admonition, impressed Lanyard as significantly inconsistent. Sophie was no more a woman to make purposeless gestures than she was one sufficiently wanting in finesse to signal him by pressures of her foot. There was sheer intention in that iteration: "... _lose no time ... you must not miss this opportunity_." Something had happened even since their dance; she had observed something momentous, and was warning him to act quickly if he meant to act at all.

With unruffled amiability, amused, urbane, Lanyard bowed his pet.i.tion across the table, and was rewarded by a bright nod of promise.

Lighting another cigarette, he lounged back, poised his wine gla.s.s delicately, with the eye of a connoisseur appraised its pale amber tint, touched it lightly to his lips, inhaling critically its bouquet, sipped, and signified approval of the vintage by sipping again: all without missing one bit of business in a scene enacted on the far side of the room, directly behind him but reflected in a mirror panel of the wall he faced.

The diplomatist charged with the task of discriminating the sheep from the goats in the lower lobby had come up to confer with his colleague, the maitre d'hotel of the upper storey. When Lanyard first saw the man he was standing by the elevator shaft, none too patiently awaiting the attention of the other, who, caught by inadvertence at some distance, was moving to join him, with what speed he could manage threading the thick-set tables.

Was this what Sophie had noticed? Had she likewise, perhaps, received some secret signal from the guardian of the lower gateway?

A signal possibly indicating that Ekstrom had arrived

They met at last, those two, and discreetly confabulated, the maitre d'hotel betraying welcome mitigation of that nervous tension which had heretofore so palpably affected him; and, as the other stepped back into the elevator, Lanyard saw this one's glance irresistibly attracted to the table dedicated to the service of the Princess de Alavia. Something much resembling satisfaction glimmered in the fellow's leaden eyes: it was apparent that he antic.i.p.ated early relief from a distasteful burden of responsibility.

Then, at ease in the belief that he was un.o.bserved, he turned to a near-by table round which four sat without the solace of feminine society--four men whose stamp was far from rea.s.suring despite their strikingly quiet demeanour and inconspicuously correct invest.i.ture of evening dress.

Two were unmistakable sons of the Fatherland; all were well set up, with the look of men who would figure to advantage in any affair calling for physical competence and courage, from coffee and pistols at sunrise in the Parc aux Princes to a battle royal in a Tenderloin dive.

Their table commanded both ways out, by the stairs and by the elevator, much too closely for Lanyard's peace of mind.

And more than one looked thoughtfully his way while the maitre d'hotel hovered above them, murmuring confidentially.

Four nods sealed an understanding with him. He strutted off with far more manner than had been his at any time since the arrival of Lanyard, and vented an excess of spirits by berating bitterly an unhappy clown of a waiter for some trivial fault.

The first bars of another dance number sang through the confusion of voices: truly, as Sophie had foretold, a waltz.

XVIII

DANSE MACABRE

Trained in the old school of the dance, Lanyard was unversed in that graceless scamper which to-day pa.s.ses as the waltz with a generation largely too indolent or too inept of foot to learn to dance.

His was that flowing waltz of melting rhythm, the waltz of yesterday, that dance of dances to whose measures a civilization more sedate in its amus.e.m.e.nts, less jealous of its time, danced, flirted, loved, and broke its hearts.

Into the swinging movement of that antiquated waltz Lanyard fell without a qualm of doubt, all ignorant as he was of his benighted ignorance; and instantly, with the ease and gracious a.s.surance of a dancer born, Cecelia Brooke adapted herself to his step and guidance, with rare pliancy made her every movement exquisitely synchronous with his.
