Tanza smiled.
"I will answer your questions one at a time," he said coolly. "You ask me why this outrage. Now, I put it to you as a far-seeing man with more than the ordinary share of brains—would you have preferred us to bring you on board the yacht, or would you rather have had the thing done through the medium of a policeman?"
"You are talking rubbish," Bark blustered.
"My good Bark, I am not in the habit of talking rubbish, as you very well know. It suits Mr. Grey and myself to work this matter out in our own way, without fuss or bother. Besides, we wanted to remove you beyond reach of temptation. So long as you were free to go your own way there was always the danger of Mrs. Charlock's jewels falling into your hands. And we objected to that. You will stay here just as long as we like, and, if I am anything of a prophet, you will be thanking us before long for the interest we have taken in your welfare."
"I am a free British subject," Bark cried.
"No, I beg your pardon, you are nothing of the sort. You are a prisoner on board this yacht, and here you are likely to remain for the present. Besides, how long would you be free if you once got ashore? I have only to mention one or two matters which we know of to the police and your boasted freedom would come to a speedy end. You may as well take it quietly. You will gain nothing by bluster, and you can't frighten my crew. If I were to put you in irons and take you a voyage round the world, not one of my men would interfere. But you need not be alarmed. I have not the least desire for your company on a voyage of circumnavigation, and that, singularly enough, is why you are here to-night. I know the remark sounds illogical, but you will see how sensible it is before long."
"Go on," Bark said theatrically. "Keep it up. I see that you are enjoying yourself."
"I am," Tanza said crisply. "Nothing gives me such pleasure as the elucidation of a crime. It is a positive joy to me to bring a scoundrel to book. And yet I am really the best friend you have, because I am saving you later from being charged with the murder of Mrs. John Charlock!"
