“You see, sir,” said Battle, encouraged by his support, “we do know a little about the case. If we don’t know who gains by his death, we do know who loses by it.” “Meaning?” said Isaacstein. His black eyes were bent upon the detective. More than ever, he reminded Battle of a hooded cobra. “You and Mr. Lomax, not to mention the Loyalist party of Herzoslovakia. If you’ll pardon the expression, sir, you’re in the soup.” “Really, Battle,” interposed George, shocked to the core. “Go on, Battle,” said Isaacstein. “In the soup describes the situation very accurately. You’re an intelligent man.” “You’ve got to have a King. You’ve lost your King—like that!” He snapped his large fingers. “You’ve got to find another in a hurry, and that’s not an easy job. No, I don’t want to know the details of your scheme, the bare outline is enough for me, but, I take it, it’s a big deal?” Isaacstein bent his head slowly. “It’s a very big deal.” “That brings me to my second question. Who is the next heir to the throne of Herzoslovakia?” Isaacstein looked across at Lomax. The latter answered the question, with a certain reluctance, and a good deal of hesitation: “That would be—I should say—yes, in all probability Prince Nicholas would be the next heir.” “Ah!” said Battle. “And who is Prince Nicholas?” “A first cousin of Prince Michael’s.” “Ah!” said Battle. “I should like to hear all about Prince Nicholas, especially where he is at present.” “Nothing much is known of him,” said Lomax. “As a young man, he was most peculiar in his ideas, consorted with Socialists and Republicans, and acted in a way highly unbecoming to his position. He was sent down from Oxford, I believe, for some wild escapade. There was a rumour of his death two years later in the Congo, but it was only a rumour. He turned up a few months ago when news of the Royalist reaction got about.” “Indeed?” said Battle. “Where did he turn up?” “In America.” “America!” Battle turned to Isaacstein with one laconic word: “Oil?” The financier nodded. “He represented that if the Herzoslovakians chose a King, they would prefer him to Prince Michael as being more in sympathy with modern enlightened ideas, and he drew attention to his early democratic views and his sympathy with Republican ideals. In return for financial support, he was prepared to grant concessions to a certain group of American financiers.” Superintendent Battle so far forgot his habitual impassivity as to give vent to a prolonged whistle. “So that is it,” he muttered. “In the meantime, the Loyalist party supported Prince Michael, and you felt sure you’d come out on top. And then this happens!” “You surely don’t think——” began George. “It was a big deal,” said Battle. “Mr. Isaacstein says so. And I should say that what he calls a big deal _is_ a big deal.”
