Johannesburg, harassed by the ever -growing mountains of quartz dust sweeping over the city sent for him and his investigations resulted in a formula for the after treatment of quartz waste which cut three Shillings a ton off the overhead costs of the Rand and stemmed the rising tide of dust.
And they were only a few of Dain's achievements. sitting back among his retorts and tubes, coldly exact in all he put his mind to, he invented a new bleach which was whiter than white dye. plumbers knew him as the man who had hardened iridium to such a degree that it could cut glass. aviators mentally blessed him as the man whose automatic stabilisers made flight almost fool proof and robbed night flying of ninety percent of its terrors.
That made the tally of Dain's attainments, a solid, brilliant roll of honourable work done. Not bad for a man still standing on the threshold if the thirties.
And yet there was one invention, the greatest achievement of all, which never came to the light of the day. Dain conceived it, produced it, and perfected it to its last extraordinary detail and then shut it around with a vast and omnipotent silence. Locked away in his great laboratory high up among the roofs of kings way, he brought his Invention to its last ultimate degree of perfection
he tried it , tested it , and proved it out to the last degree. then he sat back quietly to think things out.
it's possibilities were amazing, it's potentialities colossal, frightening. it held out opportunities that were enough to make even the most avaricious master criminal on earth tremble.
for that amazing invention of his had given to Valmon Dain the mastery of a million secrets. it held out to him the keys of all knowledge. it put him in possession of information by which in twelve short months he could have well-nigh wrecked the social system. he could, without the shadow of a doubt, have created a corner in money; he could have forestalled every enterprises worth while; he could draw on the very well-springs of secret information, and using it with only a smattering of skill could have shaken the whole social fabric to its very roots.
And Dain, after a desperate month of mental stress, called up his reserves of courage, took his destiny in both hands and began to pick the luscious fruits of his Invention.
That laboratory became the nerve centre of the most extraordinary cross-web of tangled intrigues, the nightmarish conversations that ever existed outside the demented brain of a madman. He built his own apparatus. no other living soul had ever looked inside that room. He himself had taken the place under an assumed name. so far as the landlord knew that particular office was let to a Mr. Landring Dent, export merchant a highly respectable and worthy gentleman who paid his rent with fastidious regularity and conducted the greater part of his business by telephone.
even they had no knowledge of the amazing transformation that had been effected in their own property. the place was no longer an office with a tiny annexe. it was a Network of shinning wires and little polished dials set row on row all round the walls. Dain himself had carried up the various fittings an inconceivable number of journeys , and had assemble them with a patience that was as precise and unflagging as the skill employed in their making.And the thing had grown on him. only Dain himself knew how tremendously this hobby of his had become his dominating master. imperceptibly at first, but with a dreadful surety it had come to be the be-all and end-all of his existence. Very slowly his old haunts ceased to know him. his own home out at Hendon became little more to him than an occasional bedroom. Dain was a sporadic lodger in his own house. Equally slowly he became more and more Mr. Landring Dent, of the top floor offices in kingsway.That was Valmon
Theatre crows were pressing along Piccadilly and sdown through the Haymarket, pouring into buses and tubes and taxis. Dark massy clouds were sailing in sullen sqaudrons across the moon and there was a warm smell of rain in the air."Rather a good show, wasn't it? I thought that new girl was awfully clever----wonderfully versatile for a newcomer."A tall and very beautiful girl, with a mass of shinning brown hair crowning the clear contour of her face, glance up at her mother for confirmation as they made their way to the car park behind Leicester Square."very clever indeed, Mercia. and quite charming she actually contrived not to look ugly even when singing the highest of her top notes. A decided accomplishment".Both women were beautifully gowned , the younger one in a swathing miracle of silver tissues which in the electric glare of the great arc lamps, flashed an occasional glint if powder blue. her mother was dre
He put his headphones on again and connected his contract key with another little nickel dial on which the single ting of a bell had just sounded. For many seconds he listened with straining intentness, his left hand fiddling about abstractedly among the mass of cross-connecting wires by his shoulder.Then he muttered, "Bah!-----nothing but a sheaf of drunk and disorderly is!"He pulled off his phones, tossed them on to a baize-covered table, and went out. patent locks clicked into place as the door closed behind him.He hurried downstairs and let himself out into the fresh windy sweep of kingsway."Taxi," he called, as a driver looked inquiringly at him from the kerb."Where to sir?" The driver reached behind to open the door."Greydene---Mr. Willard Lyall's house, Highgate," He said as he climbed in. "it's just off the main road. I'll stop you when you get there."For some minutes, Dai
"But that brings me to a point. I am going down to Brighton early next. The Government are conducting some experiments in connection with a night range-finding instrument I submitted to them a few weeks ago. it will be quite interesting. Battleship firing all over the place, destroyers zipping along out of the darkness and letting fly with white-head torpedoes at illuminated targets, giant explosions shaking the sky. would you all care to come with me?""Oh I'd love to ." Mercia's delight was obvious."You will be my guests on board the official yacht. you can all come down in my car : start away from here about eight. By half-past ten we can be on board and heading out to the sea. firing begins at midnight. By four in the morning you can be safely tucked up in bed in Greydene here, or I can book you a suite if rooms at Brighton.""It all sounds too thrilling for words.""Can I make it a definite date then?""So far as i am concerned, y
Good Lord!" he muttered under his breath; what a perfectly appalling situation. Lyall, Willard Lyall a member of the silver Arrow Group and father of Mercia! And I've sent him to pentonville. I've shut him up in a penal cell just as surely as though I turned the key in him myself. the Yard will act on intimation no 34 with absolute certainty. they always have acted on my cards ever since intimation no 4 anyway, when even officialdom began to realise that.....phew! Delivery and Shaughnessy have already got the net out. they're closing in on Lyall as surely as darkness closes over the day."He tried to untangle the maze, but his jaded brain could find no pin-point of light. The posting of that letter had amassed around him a mountain of such unscalable difficulties that he felt himself getting tinier and more abjectly helpless with every minute that passed.In moments of crisis, a man is apt to resort to panic measures and in so doing it is just possible that
" Yes, I dare say," said Delbury snappishly; "but that won't bring us any nearer to getting our hands on the ghost, will it?""Ahhhr! leave the man alone. it's after doing you a good turn, he is" snorted Shaughnessy.There was silence for a minute, and then Delbury declared his unbelief in the existence of this newcomer, Lyall."Who is he?" he demanded. "Eh? Who is he? Is he the new leader of this gang of ruffians, or Is he just one of the mob? I've searched every file in the records and there isn't a trace of a Lyall big enough to be in with the silver Arrows. The only one recorded at all isn't in the possibilities. He's doing a four years stretch in pentonville and won't be out till next year.""I'm game to bet that there is a Lyall in that bunch when we get the handcuffs on 'em , anyway." said Shaughnessy grimly."thirty-four times the ghost has come through with the goods. and we've landed 'em every time. I'm game
Willard Lyall came down to breakfast and glanced at his mail. it was a fairly large pile, but nothing more than usual. Mercia often twitted him with the fact that he seemed to do most of his business by correspondence at home.He tossed one or two letters aside, matters of small moments, thrust one or two others into an inside pocket without opening them and then picked up a plain post-card. it was addressed to him in neat, upright capitals and note the London post-mark across the stamp. The date of posting was blurred and scarcely decipherable. He turned it over in curiously . on the reverse side also in black print letters, was a single sentence.A slow frown spread over his face as he read it. His hand shook and he dropped the card suddenly to the table. There was a sickly, unhealthy pallor crawling slowly over his skin, but the dark brows had come down over his eyes like a thunder cloud. He read the extraordinary thing again and a lo
Throughout breakfast Lyall was very quiet and uncommunicative. To cover his very unusual mealtime restraint he pretended a deep absorption in his morning papers. As soon as he had left the house, Mercia and her mother exchange meaning glances. "Dad seems very reserved this morning mum," said Mercia. "Probably worried about business affairs, my dear," said Mrs. Lyall. "You will come to know men in times as well as I do. And I think I know Willard very well. When a man is having a harassing time in the city, he resorts to silence." Mercia shrugged."I don't think it's mere worry," she said quietly. "I've seen dad when he has had worry before. I've seen him when he has been like a bear with a sore head. But I've never seen him like he was this morning when I came into the breakfast room. I know dad, and it seemed to me that he had received some awful shock."Mrs. Lyall looked very perturbed."A shock
