He meant to play on my fears, and the writing materials ready to hand showed me I had guessed his purpose. I was to be forced to write the necessary instructions to the skipper.

Not a word was spoken by the men. As soon as they had finished with me they went outside, leaving the door open and remained close to it.

Some few minutes passed, and then Barosa came into the room and closed the door.

“Now, Mr. Donnington, you must understand what we require you to do,” he said very peremptorily. “You have chosen to interfere in our plans, and your interference has brought you to this pass. You are absolutely in our power; and I tell you at once and frankly, that your life will depend upon your decision. You will write the instructions to Captain Bolton to go after the Rampallo, and take our friends to Oporto with all speed. As soon as they are safe, you shall be set at liberty. Not here in Lisbon; but you will go on board a steamer which will take you straight back to England, and you will have to give your word of honour not to speak a word of anything you know until you reach your country. You will also order your captain to take your yacht straight to England the moment that our friends are landed.”

“I shall do nothing of the sort, Dr. Barosa.”

“I think you will change your mind. The penalty of refusal will be—death,” he replied, as sternly and impressively as he could speak.

“Very well. I refuse absolutely,” I said, in quite as firm a tone as his. As a matter of fact, I did not believe in his threat. His object was to get his friends at liberty with the least trouble and in the quickest time, and he was bluffing me.

But if it was only bluff, he made it very realistic. “I shall give you five minutes in which to do what I require, and at the end of that time if you persist in your refusal you shall die. That I declare solemnly on my honour.”

With that he called in a couple of men and ordered them to unfasten my right hand and bind my left arm to my side, and as soon as they had done so, he sent them out again.

“I will tell you what you do not seem to know. The attempt last night on the king has become known, many arrests have been made, and we are all in danger of the same fate. At present the men who have brought you up here do not know the part you have played in betraying them; but when they learn it you know enough of them to judge how they will feel towards you, and what they will be eager to do in revenge. If on my return in five minutes from now those instructions are not written, I shall tell them everything.”
