“I shall; I’ve already sent for carpenters to demolish some parts of the house.”

“I wish I could stay up here and see the work progress. You’ll have to find the secret, you know. You can’t help it, if you tear down the whole structure.”

“I don’t mean to do that. I want to continue to live in the house. But some expert carpenters can dig into certain portions of it without making the rest uninhabitable, and that’s what I propose doing.”

“What about finger prints? I thought you detectives set great store by those.”

“Not in a case like this. Suppose we find finger prints,—they’re not likely to be those of any registered criminal. And since this talk with you, I shall turn my investigations in a slightly different channel, anyhow. I must look up Mr Varian’s past life——”

“Look all you wish, but I tell you now, you’ll find nothing indicative. Whatever secret my brother had, it was not a matter of crime,—or even of lighter wrongdoing. And, if Frederick Varian wanted to keep the matter secret neither you nor any other detective will ever find it out!”

“That may have been true during your brother’s life, Doctor, but now that he can’t longer protect his secret, it must come out.”

“All right, Mr Wise, I truly hope it will. For even if it reflects against my brother’s integrity, it may aid in finding Betty. I don’t believe that girl is dead,—do you?”

“No; I don’t. I believe these letters from the kidnappers are true bills. I believe they have her concealed and confined, and by Heaven, Doctor Varian, I’m going to find her! I know that sounds like mere bluster, but I’ve never totally failed on a case yet,—and this,—the biggest one I’ve ever tackled, shall not be my first failure! I must succeed!”

“If I can help in any way, command me. I’m glad to see you don’t think I’m criminally implicated because of the legacy of the pearls. Eleanor shall never touch them until we’ve positively concluded that Betty is dead. But that’s a small matter. Those pearls have lain undisturbed in safe deposit many years,—they may lie there many years more,—but let the search work go on steadily.”
