"That I do not know yet; I have only vague thoughts in my mind. But hate, remember, is a hard and very efficient task-master, and I hate that man, Nicolaes, almost as much as I hate the Prince of Orange. But 'tis the Prince's death which I want first; because of this my hatred of the rascal must lie dormant just a few days. But it shall lose nothing by waiting, and already I see before me visions of an exemplary revenge which shall satisfy you and gratify my hate."

"Can I help you in any way?"

"Not at present; I have no definite plans just now. All I know is that we must possess ourselves of the rascal's person as well as of Gilda without the risk of compromising ourselves. In this, of course, we have now Jan's valuable help; he is a splendid leader and entirely trustworthy where the cause of his own hatred against the Prince is served."

"And, of course, you have the thirty or forty men—mercenaries and louts—whom Heemskerk, van Does and the others have been recruiting for you."

"Exactly. I can easily detail half a dozen of them to follow Jan. That is our first move, my good Beresteyn," he added emphatically, "to gain possession of Gilda, and to capture the rascal. Only tell me this, what are the papers now in that knave's possession which might compromise you if they were found?"

"I had to write a letter to Ben Isaje, telling him to convince himself that Gilda was safe and in good health, ere he paid the rascal a sum of 3,000 guilders. This letter is writ in mine own hand and signed with my name. Then there is a formal order to Ben Isaje to pay over the money, but that was writ in the usual way by the public scrivener and is signed with the cypher which I always use in all monetary transactions with the Jew. He keeps these formal documents in his archives and all his clients use a cypher in the same way."

"How is that formal order worded?"

"As far as I remember it runs thus: 'In consideration of valuable services rendered to me by the bearer of this note, I desire you to pay him the sum of 3,000 guilders out of my monies which lie with you at interest.' The cypher signature consists of the words 'Schwarzer Kato' surmounted by a triangle."

"And is that cypher known to anyone save to Ben Isaje?"

"Alas! it is known to my father. We both use it for private business transactions."
