"I am afraid not, my boy," Ravenspur said in a dull, mechanical way. "I know that you won't chatter about this thing. And, perhaps, a little later on, I shall be able to speak more plainly. I shall be glad if you will help me up the stairs and get me into bed. I have had a great shock tonight."
It seemed almost cruel to pursue the subject further, and Walter refrained from questions as he noticed the ghastly whiteness of his uncle's face. The latter was disposed of at length, and then Walter came downstairs again. He now had the house practically to himself. All desire for sleep had forsaken him. Besides that, it was no nice thought to reflect on the possibility of that ruffian being still on the premises. Walter had not the slightest doubt in his mind that the man had left the studio in some secret manner, and that he had come there through no ordinary channel. What was to prevent him returning again when the house was asleep and finishing his work? In itself, the fact of Lord Ravenspur possessing a bitter enemy was remarkable. And Lord Ravenspur's obstinate silence was more remarkable still. Walter had given his word to say nothing of these strange events, but that did not bind him from making inquiries on his own account.
He returned to the studio once more and made a thoroughly searching examination of the place. Was there some secret door which Lord Ravenspur used, and of which nobody knew anything? It had never occurred to Walter till that moment that his uncle might have turned-down pages in his life, but that conclusion was inevitable now. Still, though Walter spent the best part of an hour in his search, he had nothing to show for his pains. He was about to give up the thing in despair when a piece of yellow paper, lying by the side of the Persian rug where Lord Ravenspur had fallen, attracted his attention. It was a small, shabby sheet of paper, folded in four and printed from worn-out type, in fact, just the class of bill which is circulated amongst travelling circuses and shows of that kind. It was the last thing in the world that anyone would have looked for in the studio of so fastidious a man as Lord Ravenspur. Slowly and thoughtfully Walter unfolded and read the handbill. It was an advertisement of the nightly programme of the Imperial Palace Theatre. The name of the place sounded imposing enough, but the locality of Vauxhall Bridge Road somewhat detracted from the importance of it. So far as Walter could judge, the Imperial Palace Theatre was no more than a shady music hall giving two shows a night, and most of the names on the bill were absolutely unknown to fame. The star turn appeared to be one Valdo, who was announced as the flying man who had made such a sensation throughout the leading halls in Europe.
"I wonder if this is a clue," Walter murmured to himself. "At any rate, I should like to see this Valdo. I'll go down to the Imperial Palace tomorrow night and enquire for myself."
Walter folded up the shabby bill and placed it in his pocket, after which he went thoughtfully to bed.
[CHAPTER VIII.]
THE MYSTERY DEEPENS.
Nobody in the Park Lane house appeared to have the slightest suspicion that anything had been wrong. The stolid, well-trained servants accepted the explanation of the broken door quite as a matter of course. And when Vera had come down in the morning she appeared to have forgotten the incident entirely. Lord Ravenspur was not feeling particularly well, and he had decided to keep to his room for the day. The explanation was perfectly simple and quite natural. All the same, Walter was thankful that Vera should ask him no questions. It was no easy matter to preserve a cheerful and unconcerned face at the breakfast table, but he seemed to manage it all right. He was just a little quiet and subdued, but then there was nothing remarkable about that, especially in view of Lord Ravenspur's feelings on the subject of his engagement to Vera.
The day dragged on, and Walter waited with what patience he had till the evening. He was not displeased to find that Vera was dining out with some friends in Sloane Square, for this would give him the opportunity he needed. He changed his dinner jacket presently for an old tweed coat and cap. Then he set out on his errand in Vauxhall Bridge Road. Walter was not alone on this occasion, for he was accompanied by a journalist friend whose particular study was the life and habits of the lower classes. It was this friend who had suggested the advisability of the humble garb, so that they could thus mix freely with the people around them. Walter congratulated himself upon his friend's prudence when he saw the class of audience that filled the Imperial Palace Theatre.
The place was large enough, and by no means lacked artistic finish. At one time it had been an actual theatre, run by some enthusiast with a view to the elevation of the masses and the production of high-class plays at popular prices. The experiment had ended in a ghastly failure, and now a shrewd, hard-headed publican in the neighbourhood was making a fortune by the simple expedient of giving his patrons exactly what they required.
