"Well, I'll put it in the form of a parable if you like," he said. "Suppose that you and I found ourselves in a very tight place. It wants no imagination to conceive that, you say. Very well, the situation is granted. We are in the warm corner, and the same man is keeping us there. I need not say I am alluding to Ralph Darnley. If I don't get him out of the way, I am a ruined man. Another few days, and I shall have to fly the country in disgrace; I shall be brought back and put on my trial. The result of that trial is a foregone conclusion and society will be deprived of my presence for some years to come. My only hope is in help of a substantial nature from you." "That's all right," Speed whispered hoarsely, "you shall have as much as you like, if you will only show me the way to raise the money." "That's precisely what I am going to do. Darnley must be got of the way. Then you will have all the money you need. Listen to me. Darnley dines here tonight. He will not stay late because of my presence. When the dinner is practically finished you will plead a headache, and go and sit in that big chair with the window open. From time to time you will put in a remark to show that you are still there. When Darnley rises to go I shall walk as far as the hall with him and help him on with his coat. It may happen that he will smoke a cigar that I shall select for him--a fresh cigar to carry him home. A few whiffs of that cigar will make him very giddy, for my cigars are strong. I have made arrangements for a message to come to Darnley about half past ten saying that Lady Dashwood desires to see him at the dower house tonight. "Now, if my memory serves me correctly, the quickest way to the dower house is along the terrace here. Darnley will go that way. He will be very giddy and sleepy. You are in the alcove whilst I am talking to old Dashwood. This is where Dashwood comes in, where he will be a witness for me. As Darnley staggers along, you get out on to the terrace. You happen to have a loaded stick handy. I don't wish to suggest any connection between the two events, but it is just possible that Darnley will be found in the park tomorrow morning, with his head split open and his pockets empty. That would be a fortunate accident for us." "Yes," Speed said with chattering teeth, "it--it would. But I don't quite----" "Oh, the rest is quite easy. I call to you directly I fancy things are safe, and you come into the room grumbling at the light. I only want you to answer a question, and so prove that you have been in the room all the time. We don't lose sight of one another after that, not till everybody has gone to bed, when I slip out and place the body so that it can be found to look as if robbery had been the motive. Can you do it?"
