Fentolin sighed and beckoned to Doctor Sarson.
"I am afraid," he whispered, "that that wonderful drug of yours, Doctor, has been even a little too far-reaching in its results. It has kept our friend so quiet that he has lost even the power of speech, perhaps even the desire to speak. A little restorative, I think - just a few drops."
Doctor Sarson nodded silently. He drew from his pocket a little phial and poured into a wine-glass which stood on a table by the side of the bed, half a dozen drops of some ruby-coloured liquid, to which he added a tablespoonful of water. Then he leaned once more over the bed and poured the contents of the glass between the lips of the semi-conscious man.
"Give him two minutes," he said calmly. "He will be able to speak then."
Mr. Fentolin nodded and leaned back in his chair. He glanced around the room a little critically. There was a thick carpet upon the floor, a sofa piled with cushions in one corner, and several other articles of furniture. The walls, however, were uncovered and were stained with damp. A great pink fungus stood out within a few inches of the bed, a grim mixture of exquisite colouring and loathsome imperfections. The atmosphere was fetid. Meekins suddenly struck a match and lit some grains of powder in a saucer. A curious odour of incense stole through the place. Mr. Fentolin nodded appreciatively.
"That is better," he declared. " Really, the atmosphere here is positively unpleasant. I am ashamed to think that our guest has had to put up with it so long. And yet," he went on, "I think we must call it his own fault. I trust that he will no longer be obstinate."
The effect of the restorative began to show itself. The man on the bed moved restlessly. His eyes were no longer altogether expressionless. He was staring at Mr. Fentolin as one looks at some horrible vision. Mr. Fentolin smiled pleasantly.
"Now you are looking more like your old self, my dear Mr. Dunster," he remarked. "I don't think that I need repeat what I said when I first came, need I? You have just to utter that one word, and your little visit to us will be at an end."
The man looked around at all of them. He raised himself a little on his elbow. For the first time, Hamel, crouching above, recognised any likeness to Mr. John P. Dunster.
"I'll see you in hell first!"
Mr. Fentolin's face momentarily darkened. He moved a little nearer to the man upon the bed.
"Dunster," he said, "I am in grim earnest. Never mind arguments.
Never mind why I am on the other side. They are restless about you in America. Unless I can cable that word to-morrow morning, they'll communicate direct with The Hague, and I shall have had my trouble for nothing. It is not my custom to put up with failure. Therefore, let me tell you that no single one of my threats has been exaggerated. My patience has reached its breaking point. Give me that word, or before four o'clock strikes, you will find yourself in a new chamber, among the corpses of those misguided fishermen, mariners of ancient days, and a few others. It's only a matter of fifty yards out to the great sea pit below the Dagger Rocks - I've spoken to you about it before, haven't I? So surely as I speak to you of it at this moment Mr. Fentolin's speech came to an abrupt termination. A convulsive movement of Meekins', an expression of blank amazement on the part of Doctor Sarson, had suddenly checked the words upon his lips. He turned his head quickly in the direction towards which they had been gazing, towards which in fact, at that moment, Meekins, with a low cry, had made a fruitless spring. The ladder down which they had descended was slowly disappearing. Meekins, with a jump, missed the last rung by only a few inches. Some unseen hand was drawing it up. Already the last few feet were vanishing in mid-air. Mr.
Fentolin sat quite quiet and still. He looked through the trap-door and saw Hamel.
"Most ingenious and, I must confess, most successful, my young friend!" he exclaimed pleasantly. "When you have made the ladder quite secure, perhaps you will be so good as to discuss this little matter with us?"
There was no immediate reply. The eyes of all four men were turned now upon that empty space through which the ladder had finally disappeared. Mr. Fentolin's fingers disappeared within the pocket of his coat. Something very bright was glistening in his hand when he withdrew it.
"Come and parley with us, Mr. Hamel," he begged. "You will not find us unreasonable."
Hamel's voice came back in reply, but Hamel himself kept well away from the opening.
"The conditions," he said, "are unpropitious. A little time for reflection will do you no harm."
The trap-doors were suddenly closed. Mr. Fentolin's face, as he looked up, became diabolic.
"We are trapped!" he muttered; "caught like rats in a hole!"
