The other made a deprecatory gesture.

“Really I beg of you, Mr. Cheyne,” he said in mock horror at the other’s violence. “Not so fast, if you please, sir. I have an answer to both your observations. With regard to the door you will—”

Cheyne interrupted him with a savage oath and a fierce onslaught of kicks on the lower panels of the door. But he could make no impression on them, and when in a few moments he paused breathless, Lamson went on quietly.

“With regard to the door, as I was about to observe, it would be a waste of energy to attempt to smash it to splinters, because I have taken the precaution to have it covered with steel plates. They are bolted through and the nuts are on the outside. I mention this to save you—”

Cheyne was by this time almost beside himself with rage. He expressed his convictions and desires as to Lamson and his future in terms which from the point of view of force left little to be desired, and persistently reiterated his demand that the door be opened as a prelude to further negotiation. In reply Lamson shook his head, and remarking that as the present seemed an inopportune moment for discussing the situation, he could postpone the conversation, he closed the panel and left the inner cabin once more in darkness.

For an hour Cheyne stormed and fumed, and with pieces which he managed to knock off the table tried to break through the door, the bulkheads, and the deadlighted porthole, all with such a complete absence of success that when at last Lamson appeared once more at the panel he was constrained to listen, though with suppressed fury, to what he had to say.

“You see, it’s this way, Mr. Cheyne,” the erstwhile inventor began. “You are completely in our power, and the sooner you realize it and let us come to business, the sooner you’ll be at liberty again. We don’t wish you any harm; please accept my assurances on that. All we want is a slight service at your hands, and when you perform it you will be free to return home; in fact we shall take you back as I said, with profuse apologies for your inconvenience and loss of time. But it is only fair to point out that we are determined to get what we want, and if you are not prepared to come to terms now we can wait until you are.”

Cheyne, still at a white heat, cursed the other savagely. Lamson waited until he had finished, then went on in a smooth, almost coaxing tone:

“Now do be reasonable, Mr. Cheyne. You must see that your present attitude is only wasting time for us both. Not to put too fine a point on it, the situation is this: You are there, and you can’t get out, and you can’t attract attention to your predicament—that is why the deadlights are shipped. It grieves me to say it,” Lamson smiled sardonically, “but I must tell you that you will stay there until you do what we want. In order to prevent Mrs. Cheyne becoming uneasy we shall wire her in your name that you have left for an extended trip and won’t be back for some days. ‘To Cheyne, Warren Lodge, Dartmouth. Gone for yachting cruise down French coast. Address Poste Restante, St. Nazaire. All well. Maxwell.’ You see, we know exactly how to word it. All suspicion would be lulled for some days and then,” he paused and something sinister and revolting came into his face, “then it wouldn’t matter, for it would be too late. For you see there is neither food nor drink in the cabin and we don’t propose to pass any in. You won’t get any, Mr. Cheyne, no matter how many days you remain aboard: that is,” his manner changed, “unless you are reasonable, which of course you will be. In that case no harm is done. Now won’t you hear our little proposition?”

“I’ll see you in hell first,” Cheyne shouted, his rage once again overwhelming him. “You’ll pay for this, I can tell you. It’ll be the dearest trip you ever had in your life,” and he proceeded with threats and curses to demand the immediate opening of the door. Lamson, a whimsical smile curling his lips, shrugged his shoulders at the outburst, and replied by withdrawing his head from the opening and sliding the panel to.
