"This isn't to be altogether a pleasure trip, Dick," went on Mr. Hamilton, when he and his son were alone in the reception hall. "I suppose you got my letter, telling you about some distant relatives I need to locate?" "Yes, I got your note, but you didn't go into details." "No, it wasn't exactly safe, in a letter. I'll tell you about it now, and I hope you can combine business and pleasure. How would you like to sail for Cuba?" "Cuba? Fine! That would suit me." "Well, I'd like to have you make a trip down there, and, after you find the persons I'm looking for, you can cruise somewhere else; along the New England coast, if you like." "All right, dad. Let's hear the story." "I think I never told you," began Mr. Hamilton, "that your mother had some distant relatives in Cuba. One of her cousins named Rose Martin married a Cuban gentleman, named Raphael Valdez. For a time they were quite well off, but, just before your mother left us she learned that her cousin had died, and that her husband and son were in want. "Your mother endeavored to send them some relief, but just then the Spanish-American war broke out, and all trace was lost of the Valdez family, who were of Spanish extraction. Your mother grieved very much at not being able to help her relatives, even if they were so distantly related, and I promised that I would aid her. "Then--then came your mother's death," and Mr. Hamilton's voice faltered. "I had many cares, and the matter slipped from my mind. Now, it is to find, if possible, these people that I wish you to go to Cuba, Dick." "In order to give them aid?" "Yes, if they need it; but also for another reason. That reason I hinted at in my letter. It seems that, some time ago, your mother purchased a large piece of valuable property in the business section of New York. It has increased in value of late, and a syndicate has been formed to erect a large office building on it. I am interested in it--in fact, I hold a majority of the stock. "Well, when the time came to interest outsiders, and borrow money to erect the building, for I do not care to finance it all alone, we found that there was a flaw in the deed. Your mother paid cash for the property, and she thought she had a good title, but it seems that now, when the ownership has passed to me by will, that the names of this Senor Valdez and his son are needed on the deed." "And you want me to locate them, and get their signatures?" asked Dick.
