"Let them see the letter," Macloud answered, "but on the distinct stipulation, that they make no effort to apprehend 'Robert Parmenter's Successors' until the women are safely returned. They may pick up whatever clues they can obtain for after use, but they must not do anything which will arouse suspicion, even." "Why take them into our confidence at all?" asked Croyden. "For two reasons: It's acting square with them (which, it seems to me, is always the wise thing to do). And, if they are not let in on the facts, they may blunder in and spoil everything. We want to save the women at the earliest moment, without any possible handicaps due to ignorance or inadvertence." "But can we trust them?" Croyden asked, doubtfully. "It's the lesser of two evils." "We will have to explain the letter, its reference to the Parmenter jewels, and all that it contains." "I can see no objection. We didn't find the treasure, and, I reckon, they're welcome to search, if they think there is a chance." "Well, let it be exactly as you wish--you're quite as much concerned for success as I am," said Croyden. "Possibly, more so," returned Macloud, seriously. And Croyden understood. Then, they went into the library. The two detectives arose at their entrance. The one, Rebbert, was a Pinkerton man, the other, Sanders, was from the Bureau at City Hall. Both were small men, with clean shaven faces, steady, searching eyes, and an especially quiet manner. "Mr. Croyden," said Rebbert, "we have been questioning the servants, but have obtained nothing of importance, except that the ladies wore their hats and coats (at least, they have disappeared). This, with the fact that you found Miss Cavendish's glove and handkerchief, on a road without the limits of Hampton, leads to the conclusion that they have been abducted. But why? Miss Carrington, we are informed, has no great wealth--how as to Miss Cavendish?" "She has more than sufficient--in fact, she is very rich----" "Ah! then we _have_ a motive," said the detective. "There is a motive, but it is not Miss Cavendish," Croyden answered. "You're correct as to the abduction, however--this will explain," and he handed him the letter. The two men read it. "When did you receive this?" said one. "At noon to-day," replied Croyden, passing over the envelope. They looked carefully at the postmark. "Do you object to explaining certain things in this letter?" Rebbert asked. "Not in the least," replied Croyden. "I'll tell you the entire story.... Is there anything I have missed?" he ended. "I think not, sir." "Very well! Now, we prefer that you should take no measures to apprehend the abductors, until after Miss Cavendish and Miss Carrington have been released. We are going to pay the amount demanded." "Going to pay the two hundred thousand dollars!" cried the detectives, in one breath. Croyden nodded. "Afterward, you can get as busy as you like." A knowing smile broke over the men's faces, at the same instant.
