Prince Aribert never stirred from his position behind the great red hat.

The game continued. Racksole lost trifles from time to time, but ninety- nine hundredths of the luck was with him. As an English spectator at the table remarked, 'he couldn't do wrong.' When midnight struck the lady in the red hat was reduced to a thousand francs. Then she fell into a winning vein for half an hour, but at one o'clock her resources were exhausted. Of the hundred and sixty thousand francs which she was reputed to have had early in the evening, Racksole held about ninety thousand, and the bank had the rest.

It was a calamity for the Juno of the red hat. She jumped up, stamped her foot, and hurried from the room. At a discreet distance Racksole and the Prince pursued her.

'It might be well to ascertain her movements,' said Racksole.

Outside, in the glare of the great arc lights, and within sound of the surf which beats always at the very foot of the Kursaal, the Juno of the red hat summoned a fiacre and drove rapidly away. Racksole and the Prince took an open carriage and started in pursuit. They had not, however, travelled more than half a mile when Prince Aribert stopped the carriage, and, bidding Racksole get out, paid the driver and dismissed him.

'I feel sure I know where she is going,' he explained, 'and it will be better for us to follow on foot.'

'You mean she is making for the scene of last night's affair?' said Racksole.

'Exactly. We shall--what you call, kill two birds with one stone.'

Prince Aribert's guess was correct. The lady's carriage stopped in front of the house where Nella Racksole and Miss Spencer had had their interview on the previous evening, and the lady vanished into the building just as the two men appeared at the end of the street. Instead of proceeding along that street, the Prince led Racksole to the lane which gave on to the backs of the houses, and he counted the houses as they went up the lane. In a few minutes they had burglariously climbed over a wall, and crept, with infinite caution, up a long, narrow piece of ground--half garden, half paved yard, till they crouched under a window--a window which was shielded by curtains, but which had been left open a little.

'Listen,' said the Prince in his lightest whisper, 'they are talking.'

'Who?'

'The Berlin lady and Miss Spencer. I'm sure it's Miss Spencer's voice.'

Racksole boldly pushed the french window a little wider open, and put his ear to the aperture, through which came a beam of yellow light.

'Take my place,' he whispered to the Prince, 'they're talking German.

You'll understand better.'

Silently they exchanged places under the window, and the Prince listened intently.

'Then you refuse?' Miss Spencer's visitor was saying.

There was no answer from Miss Spencer.

'Not even a thousand francs? I tell you I've lost the whole twenty-five thousand.'

Again no answer.

'Then I'll tell the whole story,' the lady went on, in an angry rush of words. 'I did what I promised to do. I enticed him here, and you've got him safe in your vile cellar, poor little man, and you won't give me a paltry thousand francs.'

'You have already had your price.' The words were Miss Spencer's. They fell cold and calm on the night air.

'I want another thousand.'

'I haven't it.'

'Then we'll see.'

Prince Aribert heard a rustle of flying skirts; then another movement--a door banged, and the beam of light through the aperture of the window suddenly disappeared. He pushed the window wide open. The room was in darkness, and apparently empty.

'Now for that lantern of yours,' he said eagerly to Theodore Racksole, after he had translated to him the conversation of the two women, Racksole produced the dark lantern from the capacious pocket of his dust coat, and lighted it. The ray flashed about the ground.

'What is it?' exclaimed Prince Aribert with a swift cry, pointing to the ground. The lantern threw its light on a perpendicular grating at their feet, through which could be discerned a cellar. They both knelt down, and peered into the subterranean chamber. On a broken chair a young man sat listlessly with closed eyes, his head leaning heavily forward on his chest.

In the feeble light of the lantern he had the livid and ghastly appearance of a corpse.

'Who can it be?' said Racksole.

'It is Eugen,' was the Prince's low answer.

Chapter Seventeen THE RELEASE OF PRINCE EUGEN

'EUGEN,' Prince Aribert called softly. At the sound of his own name the young man in the cellar feebly raised his head and stared up at the grating which separated him from his two rescuers. But his features showed no recognition. He gazed in an aimless, vague, silly manner for a few seconds, his eyes blinking under the glare of the lantern, and then his head slowly drooped again on to his chest. He was dressed in a dark tweed travelling suit, and Racksole observed that one sleeve--the left-- was torn across the upper part of the cuff, and that there were stains of dirt on the left shoulder. A soiled linen collar, which had lost all its starch and was half unb.u.t.toned, partially encircled the captive's neck; his brown boots were unlaced; a cap, a handkerchief, a portion of a watch-chain, and a few gold coins lay on the floor. Racksole flashed the lantern into the corners of the cellar, but he could discover no other furniture except the chair on which the Hereditary Prince of Posen sat and a small deal table on which were a plate and a cup.

'Eugen,' cried Prince Aribert once more, but this time his forlorn nephew made no response whatever, and then Aribert added in a low voice to Racksole: 'Perhaps he cannot see us clearly.'

'But he must surely recognize your voice,' said Racksole, in a hard, gloomy tone. There was a pause, and the two men above ground looked at each other hesitatingly. Each knew that they must enter that cellar and get Prince Eugen out of it, and each was somehow afraid to take the next step.

'Thank G.o.d he is not dead!' said Aribert.

'He may be worse than dead!' Racksole replied.

'Worse than--What do you mean?'

'I mean--he may be mad.'

'Come,' Aribert almost shouted, with a sudden access of energy--a wild impulse for action. And, s.n.a.t.c.hing the lantern from Racksole, he rushed into the dark room where they had heard the conversation of Miss Spencer and the lady in the red hat. For a moment Racksole did not stir from the threshold of the window. 'Come,' Prince Aribert repeated, and there was an imperious command in his utterance. 'What are you afraid of?'

'I don't know,' said Racksole, feeling stupid and queer; 'I don't know.'

Then he marched heavily after Prince Aribert into the room. On the mantelpiece were a couple of candles which had been blown out, and in a mechanical, unthinking way, Racksole lighted them, and the two men glanced round the room. It presented no peculiar features: it was just an ordinary room, rather small, rather mean, rather shabby, with an ugly wallpaper and ugly pictures in ugly frames. Thrown over a chair was a man's evening-dress jacket. The door was closed. Prince Aribert turned the k.n.o.b, but he could not open it.

'It's locked,' he said. 'Evidently they know we're here.'

'Nonsense,' said Racksole brusquely; 'how can they know?' And, taking hold of the k.n.o.b, he violently shook the door, and it opened. 'I told you it wasn't locked,' he added, and this small success of opening the door seemed to steady the man. It was a curious psychological effect, this terrorizing (for it amounted to that) of two courageous full-grown men by the mere apparition of a helpless creature in a cellar. Gradually they both recovered from it. The next moment they were out in the pa.s.sage which led to the front door of the house. The front door stood open. They looked into the street, up and down, but there was not a soul in sight. The street, lighted by three gas-lamps only, seemed strangely sinister and mysterious.

'She has gone, that's clear,' said Racksole, meaning the woman with the red hat.

'And Miss Spencer after her, do you think?' questioned Aribert.

'No. She would stay. She would never dare to leave. Let us find the cellar steps.'

The cellar steps were happily not difficult to discover, for in moving a pace backwards Prince Aribert had a narrow escape of precipitating himself to the bottom of them. The lantern showed that they were built on a curve.

Silently Racksole resumed possession of the lantern and went first, the Prince close behind him. At the foot was a short pa.s.sage, and in this pa.s.sage crouched the figure of a woman. Her eyes threw back the rays of the lantern, shining like a cat's at midnight. Then, as the men went nearer, they saw that it was Miss Spencer who barred their way. She seemed half to kneel on the stone floor, and in one hand she held what at first appeared to be a dagger, but which proved to be nothing more romantic than a rather long bread-knife.
