"With pleasure," said the other; "there is a storeroom up above which you may see if you wish."
He led the way upstairs, unlocked the door of the room immediately over that which they had just left, and entered. The room was bare, and the plain deal floor, the distempered walls, and the high skylight showed it to be just as the doctor had described, a typical storeroom.
"You do not seem to use it," said T. B.
"We are very tidy people," smiled the doctor; "and now you shall see the room below."
As they went down the stairs again they heard the curious wail, and T. B. experienced a tremulous jar which he had noted before.
"Unpleasant, is it not?" said Dr. Fall. "I was quite alarmed at that at first, but it has no unpleasant consequences."
On the second floor he entered the third room, immediately below that in which the sick Mr. Moole was lying. He unlocked this door and they entered a well-furnished bedroom; on a more elaborate scale than that which T. B. had seen before.
"This is our spare bedroom," said Dr. Fall, easily; "we seldom use it."
T. B. slipped into the apartment and made a quick scrutiny. There was nothing of a suspicious character here.
"I hope you are satisfied now," said Dr. Fall as he led the way out, "and that your two friends below are not growing impatient."
"You have seen them, then," said T. B.
"I have seen them," said the other gravely. "I saw them a few moments after you entered the hall. You see, Mr. Smith," he went on, "we do not employ anything so vulgar as bells to alarm us. When the entrance door opens, a red light shows above my bed. Unfortunately, the moment you came in I happened to be in an adjoining room at work. I had to go into my bedroom to get a paper, when I saw the light. So, though I am perhaps inaccurate in saying that I have been keeping you under observation from the moment you arrived, there was little you did which was not witnessed. I will show you, if you will be good enough to accompany me to my room."
"I shall be delighted," said T. B.
He was curious to learn anything that the house or its custodian could teach him. Dr. Fall's room was on the first floor, immediately over the entrance hall, a plain office with a door leading to a cosily, though comparatively expensively furnished bedroom. By the side of the doctor's bed was a round pillar, which looked for all the world like one of those conventional and useless articles of furniture which the suburban housewife employs to balance a palm upon.
"Look down into that," said the doctor.
T. B. obeyed. It was quite hollow, and a little way down was what appeared to be a square sheet of silver paper. It was unlike any other silver paper because it appeared to be alive. He could see figures standing against it, two figures that he had no difficulty in recognizing as Ela and Johnson.
"It is a preparation of my own," said the doctor. "I thought of taking out a patent for it. An adjustment of mirrors throws the image upon a luminous screen which is so sensitive to light that it can record an impression of your two friends even in the semi-darkness of the hall."
"Thank you," said T. B.
There was nothing to do but to accept his defeat as graciously as possible. For baffled he was, caught at every turn, and puzzled, moreover, by his extraordinary experience.
"You will find some difficulty in opening the door," said the pleasant Doctor Fall.
"In that I think you are mistaken," smiled T. B.
The doctor stopped to switch on the light, and the two discomforted detectives watched the scene curiously.
"We have left the door ajar."
"Still I think you will find a difficulty in getting out," insisted the other. "Open the door."
Ela pulled at it, but it was impossible to move the heavy oaken panel.
"Electrically controlled," said the doctor; "and you can neither move it one way nor the other. It is an ingenious idea of mine, for which I may also apply for a patent one of these days."
He took a key from his pocket and inserted it in an almost invisible hole in the oak panelling of the hall; instantly the door opened slowly.
"I wish you a very good night," said Doctor Fall, as they stood on the steps. "I hope we shall meet again."
"You may be sure," said T. B. Smith, grimly, "that we shall."
CHAPTER XIII
Doris Gray was face to face with a dilemma. She stood in a tragic position; even now, she could not be sure that her guardian was dead. But dead or alive, he had left her a terrible problem, for terrible it seemed to her, for solution.
She liked Frank Doughton well enough, but she was perhaps too young, had too small a knowledge of the great elements of life to appreciate fully her true feelings in the matter; and then the influence of this polished man of the world, this Count of the Roman Empire as he described himself, with his stories of foreign capitals, his easy conversation, his acquaintance with all the niceties of social intercourse, had made a profound impression upon her. At the moment, she might not say with any certainty, whether she preferred the young Englishman or this suave man of the world.
The balance was against Frank, and the command contained in the will, the knowledge that she must, so she told herself, make something of a sacrifice, was a subject for resentment. Not even the sweetest girl in the world, obeying as she thought the command of a dead man, who was especially fond and proud of her, could be compensated for the fact that he had laid upon her his dead hands, charging her to obey a command which might very easily be repugnant and hateful to her.
She did not, in truth, wish to marry anybody. She could well afford to allow the question of her fortune to lapse; she had at least five years in which to make up her mind, as to how she felt toward Frank Doughton. She liked him, there was something especially invigorating and wholesome in his presence and in his very attitude towards her. He was so courteous, so kindly, so full of quick, strong sympathy and yet – there were some depths he could not touch, she told herself, and was vague herself as to what those depths were.
She was strolling in Green Park on a glorious April morning, in a complacent mood, for the trees were in fresh green bud and the flower beds were a blaze of colour, when she met Frank, and Frank was so obviously exhilarated that something of his enthusiasm was conveyed to her. He saw her before she had seen him, and came with quickening footsteps toward her.
"I say," he said explosively, "I have some splendid news!"
"Let us sit down," she said, with a kindly smile, and made a place for him by her side on a bench near by. "Now, what is this wonderful news?"
"You remember Mr. Farrington gave me a commission to find the missing heir of Tollington?"
She nodded.
"Well, I have found him," he said, triumphantly; "it is an extraordinary thing," he went on, "that I should have done so, because I am not a detective. I told Mr. Farrington quite a long time ago that I never expected to make any discovery which would be of any use to him. You see Mr. Farrington was not able to give me any very definite data to work on. It appears that old Tollington had a nephew, the son of his dead sister, and it was to this nephew that his fortune was left. Tollington's sister had been engaged to a wealthy Chicago stockbroker, and the day before the wedding she had run away with an Englishman, with whom her family was acquainted, but about whom they knew very little. She guessed that he was a ne'er-do-well, who had come out to the States to redeem his fallen fortune. But he was not a common adventurer apparently, for he not only refused to communicate with the girl's parents, although he knew they were tremendously wealthy, but he never allowed them to know his real name. It appears that he was in Chicago under a name which was not his own. From that moment they lost sight of him. In a roundabout way they learned that he had gone back to England and that he had by his own efforts and labours established himself there. This news was afterwards confirmed. The girl was in the habit of writing regularly to her parents, giving neither her surname nor address. They answered through the columns of the London Times. That is how, though they knew where she was situated, all efforts to get in touch with her proved to be unavailing; and when her parents died, and her brother renewed his search, he was met with a blank wall. You see," Frank went on, a little naïvely, "it is quite impossible to discover anybody when their name is not even known to one."
"I see," smiled the girl; "and have you succeeded where all these people have failed?"
"I have hardly progressed so far as that," he laughed. "What I have discovered is this: that the man, who seventy years ago left the United States with the sister of old Tollington, lived for some years in Great Bradley."
"Great Bradley!" she said, in surprise; "why, isn't that where Lady Constance Dex lives?"
He nodded.
"Everybody seems to live there," he said, ruefully; "even our friend," he hesitated.
"Our friend?" she repeated, inquiringly.
"Your friend Poltavo is there now," he said, "permanently established as the guest of Dr. Fall. You have heard of the Secret House? – but everybody in England has heard of it."
"I am afraid that everybody does not include me," she smiled, "but go on with your story; how did you find that he lived in Great Bradley?"
"Well, it was rather a case of luck," he explained. "You see, I lived some years in Great Bradley myself; that is where I first met your uncle. I was a little boy at the time. But it wasn't my acquaintance with Great Bradley which helped me. Did you see in the paper the other day the fact that, in pulling down an old post office building, a number of letters were discovered which had evidently slipped through the floor of the old letter-box, and had not been delivered?"
"I read something about it," she smiled; "forty or fifty years old, were they not?"
