There was no possible mistake about it. The photographs were excellent and Desmond had no difficulty in identifying the eccentric-looking German in each of them. So this was Mrs.

Malplaquet's house, was it? A nursing-home run by "No. 13," who in addition to being a spy, would seem to have been a nerve specialist as well. In this guise, no doubt, he had made trips to the South of England which had gained for him that intimate acquaintance with Portsmouth and Southsea of which he had boasted at the gathering in the library. In this capacity, moreover, he had probably met Bellward whose "oggult" powers, to which "No.

13" had alluded, seem to point to mesmerism and kindred practices in which German neurasthenic research has made such immense progress.

Pondering over his surprising discovery, Desmond pursued his way to the floor above. Here, too, was a green baize door which opened on to a corridor. Desmond walked quickly along it, glancing in, as he pa.s.sed, at the open doors of two or three bedrooms. Just beyond where the staircase crossed the corridor were two doors, both of which were closed. The one was a white door and might have been a bathroom; the other was enameled a brilliant, glossy red.

The second floor was as silent and deserted as the corridor below. But just as Desmond pa.s.sed the head of the main staircase he heard the sound of voices. He glanced cautiously down the well of the stairs and saw Strangwise and Bellward talking together.

Bellward was on the stairs while Strangwise stood in the corridor.

"It's our last chance," Strangwise was saying.

"No, no," Bellward replied heatedly, "I tell you it is madness.

We must not delay a minute. For Heaven's sake, leave the girl alone and let's save ourselves."

"What?" cried Strangwise, "and abandon Minna!"

"Minna is well able to look after herself," answered Bellward in a sulky voice, "it's a question of sauve qui peut now... every man for himself!"

"No!" said Strangwise firmly, "we'll wait for Minna, Bellward.

You exaggerate the danger. I tell you I was at the garden wall within a few seconds of our friend laying you out, and I saw no sign of him in his garden. It was a physical impossibility for him to have got over the wall and back into the house in the time. And in his garden there's nowhere to hide. It's as bare as the Sahara!"

"But, good Heavens!" cried Bellward, throwing his hands excitedly above his head, "the man can't dissolve into thin air. He's gone back to the house, I tell you, and the police will be here at any minute. You know he's not in our garden; for you searched every nook and corner of it yourself. Okewood may be too clever for you, Strangwise; but he's not a magician!"

"No," said Strangwise sternly, "he is not." And he added in a low voice:

"That's why I am convinced that he is in this house!"

Desmond felt his heart thump against his ribs.

Bellward seemed surprised for he cried quickly:

"What? Here?"

Strangwise nodded.

"You stand here gossiping with that man loose in the house?"

exclaimed Bellward vehemently, "why the next thing we know the fellow will escape us again!"

"Oh, no, he won't" retorted the other. "Every window on the ground floor is barred... this is a home for neurasthenics, you know, and that is sometimes a polite word for a lunatic, my friend... and the doors, both front and back are locked. The keys are here!"

Desmond heard a jingle as Strangwise slapped his pocket.

"All the same," the latter went on, "it is as well to be prepared for a sudden change of quarters. That's why I want you to finish off the girl at once. Come along, we'll start now..."

"No, no!" declared Bellward. "I'm far too upset. You seem to think you can turn me on and off like you do the gas!"

"Well, as you like," said Strangwise, "but the sooner we clear up this thing the better. I'm going to see if our clever young friend has taken refuge in the servants' quarters upstairs. He's not on this floor, that's certain!"

Desmond drew back in terror. He heard the green baize door on the floor below swing back as Strangwise went out to the back stairs and Bellward's heavy step ascended the main staircase. There was something so horribly sinister in that firm, creaking tread as it mounted towards him that for the moment he lost his head. He looked round wildly for a place of concealment; but the corridor was bare. Facing him was the red enamel door. Boldly he turned the handle and walked in, softly closing the door behind him.

It was as though he had stepped into another world. The room in which he found himself was a study in vivid red emphasized by black. Red and black; these were the only colors in the room. The curtains, which were of black silk, were drawn, though it was not yet dark outside, and from the ceiling was suspended a lamp in the shape of a great scarlet bowl which cast an eerie red light on one of the most bizarre apartments that Desmond had ever seen.

It was a lacquer room in the Chinese style, popularized by the craze for barbaric decoration introduced by Bakst and the Russian Ballet into England. The walls were enameled the same brilliant glossy red as the door and hung at intervals with panels of magnificent black and gold lacquer work. The table which ran down the centre of the room was of scarlet and gold lacquer like the fantastically designed chairs and the rest of the furniture. The heavy carpet was black.

Desmond did not take in all these details at once; for his attention was immediately directed to a high-backed armchair covered in black satin which stood with its back to the door. He stared at this chair; for, peeping out above the back, making a splash of deep golden brown against the black sheen of the upholstery, was a ma.s.s of curls... Barbara Mackwayte's hair.

As he advanced towards the girl, she moaned in a high, whimpering voice:

"No, no, not again! Let me sleep! Please, please, leave me alone!"

Desmond sprang to her side.

"Barbara!" he cried and never noticed that he called her by her Christian name.

Barbara Mackwayte sat in the big black armchair, facing the black-curtained window. Her face was pale and drawn, and there were black circles under her eyes. There was a listless yet highly-strung look about her that you see in people who habitually take drugs.

She heeded not the sound of his voice. It was as though he had not spoken. She only continued to moan and mutter, moving her body about uneasily as a child does when its sleep is disturbed by nightmares. Then, to his inexpressible horror, Desmond saw that her feet were bound with straps to the legs of the chair.

Her arms were similarly tethered to the arms of the chair, but her hands had been left free.

"Barbara!" said Desmond softly, "you know me! I'm Desmond Okewood!

I've come to take you home!"

The word "home" seemed to catch the girl's attention; for now she turned her head and looked at the young man. The expression in her eyes, wide and staring, was horrible; for it was the look of a tortured animal.

Desmond was bending to unbind the straps that fastened Barbara's arms when he heard a step outside the door. The curtains in front of the window were just beside him. They were long and reached to the floor. Without a second's hesitation he slipped behind them and found himself in the recess of a shallow bow window.

The bow window was in three parts and the central part was open wide at the bottom. It gave on a little balcony which was in reality the roof of a bow window of one of the rooms on the floor below. Desmond promptly scrambled out of the window and letting himself drop on to the balcony crouched down blow the sill.

A door opened in the room he had just left. He heard steps moving about and cupboards opened and shut. Then, there was the sound of curtains being drawn back and a voice said just above him:

"He's not here! I tell you the fellow's not in the house! Now perhaps you'll believe me!"

The balcony was fairly deep and it was growing dusk; but Desmond could scarcely hope to escape detection if Bellward, for he had recognized his voice, should think of leaning out of the window and looking down upon the balcony. With his coat collar turned up to hide the treacherous white of his linen, Desmond pressed himself as close as possible against the side of the house and waited for the joyful cry that would proclaim that he had been discovered. There was no possible means of escape; for the balcony stood at an angle of the house with no windows or water-pipes anywhere within reach, to give him a foothold, looking out on an inhospitable and gloomy area.

Whether Bellward, who appeared bent only on getting away from the house without delay, examined the balcony or not, Desmond did not know; but after the agony of suspense had endured for what seemed to him an hour, he heard Strangwise say:

"It's no good, Bellward! I'm not satisfied! And until I am satisfied that Okewood is not here, I don't leave this house. And that's that!"

Bellward swore savagely.

"We've searched the garden and not found him: we've ransacked the house from top to bottom without result. The fellow's not here; but by G.o.d, he'll be here presently with a bunch of police, and then it'll be too late! For the last time, Strangwise, will you clear out?"

There was a moment's pause. Then Desmond heard Strangwise's clear, calm voice.

"There's a balcony there... below the window, I mean."

"I've looked," replied Bellward, "and he's not there. You can see for yourself!"

The moment of discovery had arrived. To Desmond the strain seemed unbearable and to alleviate it, he began to count, as one counts to woo sleep. One! two! three! four! He heard a grating noise as the window was pushed further up. Five! six! seven! eight!
