Suddenly he stiffened and crouched motionless behind a bush. He had heard voices and the sound of footsteps crunching on the gravel.
“No good waiting any more,” said the man whom he recognised as Franz. “He’s dead for a certainty, and they can’t pull him out till tomorrow. Couldn’t have gone better. He swayed right over just as the car took the gates, and the bridge-keeper saw it. Think he fainted—”
Their voices died away in the distance, and Drummond came out from behind the bush. He stepped forward cautiously and found himself confronted with a high wire fence. Through it he could see a road along which the two men must have been walking. And then through a gap in the trees he saw a light in the window of a house. So his first difficulty was solved. The man called Franz and his companion could have but one destination in all probability—Maybrick Hall. And that must be the house he could see through the trees, while the road on the other side of the fence was the drive leading up to it.
He gave them half a minute or so; then he climbed through the fence. It was a fence with horizontal strands of thick wire, about a foot apart, and the top strand was two feet above Drummond’s head. An expensive fence, he reflected; an unusual fence to put round any property of such a sort. An admirable fence for cattle in a corral because of its strength, but for a house and grounds—peculiar, to say the least. It was not a thing of beauty; it afforded no concealment, and it was perfectly simple to climb through. And because Drummond had been trained in the school which notices details, even apparently trivial ones, he stood for a moment or two staring at the fence, after he had clambered through. It was the expense of the thing more than anything else that puzzled him. It was new—that was obvious, and after a while he proceeded to walk along it for a short way. And another peculiar thing struck him when he came to the first upright. It was an iron T-shaped post, and each strand of wire passed through a hole in the bottom part of the T. A perfectly simple and sound arrangement, and, but for one little point, just the type of upright one would have expected to find in such a fence. Round every hole was a small white collar, through which each strand of wire passed, so that the wires rested on the collars, and not on the holes in the iron uprights. Truly a most remarkable fence, he reflected again—in fact, a thoroughly eccentric fence. But he got no farther than that in his thoughts; the knowledge which would have supplied him with the one clue necessary to account for that fence’s eccentricity of appearance was not his. The facts he could notice; the reason for the facts was beyond him. And after a further examination he shrugged his shoulders and gave it up. There were bigger things ahead of him than a mere question of fencing, and, keeping in the shadow of the shrubs which fringed each side of the drive, he crept silently towards the house.
It was a low, rambling type of building covered as far as he could see with ivy and creepers. There were only two stories, and Hugh nodded his satisfaction. It made things simpler when outside work was more than likely. For a long time he stood in the shadow of a big rhododendron bush, carefully surveying every possible line of approach and flight, and it was while he was balancing up chances that he gradually became aware of a peculiar noise proceeding from the house. It sounded like the very faint hum of an aeroplane in the far distance, except that every two or three seconds there came a slight thud. It was quite regular, and during the four or five minutes whilst he stood there listening there was no variation in the monotonous rhythm. Thud: thud: thud—faint, but very distinct, and all the time the gentle whirring of some smooth-running, powerful engine.
The house was in darkness save for one room on the ground floor, from which the light was streaming. It was empty, and appeared to be an ordinary sitting-room. And, as a last resort, Hugh decided he would go in that way, if outside methods failed. But to start with he had no intention of entering the house; it struck him that the odds against him were unnecessarily large.
He retreated still farther into the shadow, and then quite clear and distinct the hoot of an owl was heard in the silent garden. He knew that Phyllis would recognise the call if she heard it; he knew that she would give him some sign if she could. And so he stood and waited, eagerly watching the house for any sign of movement. But none came, and after a pause of half a minute he hooted again. Of course it was possible that she was a room facing the other way, and he had already planned his line of advance round to the back of the house. And then, just as he was preparing to skirt round and investigate he saw the curtains of one of the upper rooms shake and open slightly. Very faintly he repeated the call, and to his joy he saw a head poked through between them. But he was taking no chances, and it was impossible to tell to whom the head belonged. It might be Phyllis, and on the other hand it might not. So once again he repeated the call, barely above his breath, and then he waited for some answer.
It came almost at once; his own name called very gently, and he hesitated no more. He was across the lawn in a flash and standing under her window, and once again he heard her voice tense with anxiety. “Is that you, Hugh?”
“Yes, darling, it’s me right enough,” he whispered back. “But there’s no time to talk now. I want you to jump on to the flowerbed. It’s soft landing, and it won’t hurt you.”
“But I can’t, old man,” she said, with a little catch in her breath. “They’ve got me lashed up with a steel chain.”
“They’ve got you lashed up with a steel chain,” repeated Hugh stupidly. “The devil they have; the devil they have!” And his voice was shaking a little with cold, concentrated fury. “All right, kid,” he went on after a moment; “if you can’t come to me, I must come to you. We’ll soon deal with that chain.”
He glanced into the room underneath hers and saw that it looked like a drawing-room. The windows seemed easy to force if necessary, but he decided first of all to try the ivy outside. But it was useless for a man of his weight. Just at the bottom it supported him, but as soon as he started to climb it gave way at once. Twice he got up about six feet, twice he fell back again as the ivy broke away from the wall. And after the second attempt he looked up at the anxious face of his wife above.
“No go, darling,” he muttered. “And I’m afraid of making too much noise. I’m going to try and force this window.”
By a stroke of luck they had not taken his clasp-knife, and by a still greater stroke of luck he found that the catch on the window had been broken, and that it proved even easier to open than he had thought. He stepped back and looked up.
“I’m coming in, kid,” he whispered. “Do you know where the stairs are?”
“Just about the middle of the house, old man. And listen. I can’t quite reach the door to open it, but I’ve got my parasol and I can tap on it so that you’ll know which it is.”
“Right,” he answered. “Keep your tail up.” The next moment he had vanished into the drawing-room. And now he noticed that that strange noise which he had heard while standing on the lawn was much louder. As he cautiously opened the door and peered into the passage the very faint hum became a steady drone, while with each successive thud the floorboards shook a little.
The passage was in darkness, though light was shining from under some of the doors. And as he crept along in search of the stairs he heard voices proceeding from one of the rooms he passed. Evidently a fairly populous household, it struck him, as he tested the bottom stair with his weight to see if it creaked. But the staircase was old and solid, and the stair carpet was thick, and at the moment Hugh was not disposed to linger. Afterwards the house seemed to promise a fairly fruitful field for investigation; at present
