"These endorsements, I take it," said Macloud, "though without date and signed only with initials, were made by the original addressee, Marmaduke Duval, his son, who was presumably Daniel Duval, and Daniel Duval's son, Marmaduke; the rest, of course, is plain." "That is correct," Croyden answered. "I have made inquiries--Colonel Duval's father was Marmaduke, whose son was Daniel, whose son was Marmaduke, the addressee." "Then why isn't it true?" Macloud demanded. "My dear fellow, I'm not denying it! I simply want your opinion--what to do?" "Have you shown this letter to anyone else?" "No one." "Well, you're a fool to show it even to me. What assurance have you that, when I leave here, I won't go straight to Annapolis and steal your treasure?" "No assurance, except a lamblike trust in your friendship," said Croyden, with an amused smile. "Your recent experience with Royster & Axtell and the Heights should beget confidences of this kind?" he said sarcastically, tapping the letter the while. "You trust too much in friendship, Croyden. Tests of half a million dollars aren't human!" Then he grinned. "I always thought there was something God-like about me. So, maybe, you're safe. But it was a fearful risk, man, a fearful risk!" He looked at the letter again. "Sure, it's true! The man to whom it was addressed believed it--else why did he endorse it to his son? And we can assume that Daniel Duval knew his father's writing, and accepted it.--Oh, it's genuine enough. But to prove it, did you identify Marmaduke Duval's writing--any papers or old letters in the house?" "I don't know," returned Croyden. "I'll ask Moses to-morrow." "Better not arouse his curiosity--darkies are most inquisitive, you know--where did you find the letter?" Croyden showed him the secret drawer. "Another proof of its genuineness," said Macloud. "Have you made any effort to identify this man Parmenter--from the records at Annapolis." "No--I've done nothing but look at the letter--except to trace the Duval descent," Croyden replied. "He speaks, here, of his last will and testament being left with Mr. Dulany. If it were probated, that will establish Parmenter, especially if Marmaduke Duval is the legatee. What do you know of Annapolis?" "Nothing! I never was there--I looked it up on the map I found, here, and Greenberry Point is as the letter says--across the Severn River from it." Macloud laughed, in good-natured raillery. "You seem to have been in a devil of a hurry!" he said. "At the same rate of progression, you will go to Annapolis some time next spring, and get over to Greenberry Point about autumn." "On the contrary, it's your coming that delayed me," Croyden smiled. "But for your wire, I would have started this morning--now, if you will accompany me, we'll go day-after-to-morrow." "Why delay?" said Macloud. "Why not go to-night?"
