In strange altruistic mood he asked himself why he did not spring from his chair, and, tearing the bracket from its supports, exhibit it to his fellow-worker, while he gave, in a few passionate sentences, the information that would set the French police to scour the Mediterranean littoral until they found the _White Heather_. Of what matter to him was the suffering of a sister or sweetheart? Did the man who killed Lady Dyke reck of these things? Yes, he would do it-- But a cry of triumph from the detective arrested the fateful words even as they trembled on his lips. "Here's a find!" was the shout. "Thinking is all very well, Mr. Bruce, but hard work is better. What do you make of that?" "That" was a letter, which, in the manner known to many a puzzled householder, had slipped down behind a drawer in the cabinet, to be crushed against the wardrobe at the back, and lie there forgotten and unnoticed. Even in his perturbed state the barrister could not help glancing at the crumpled document, first noting the date, October 15th of the year just closed, with the superscription, "Mountain Butts, Wyoming." There was no envelope. It was addressed to "Dear Bertie," and ran as follows: "Your welcome note and its draft for fifty dollars came to hand last week. My sisters and I can never forget your generosity. We know you are hard up, and that you can ill spare these frequent gifts, or loans, as you are pleased to call them. You and I have been in many a tight place, old chap, and I never knew you to fail either with hand or heart. And when we drifted into this ranch, on my advice, and nearly starved to death, it was you who were bold enough to cut yourself adrift so that you might make something to keep the pot boiling. "But the tide is turning. You know my failing; this time I will try not to be too sanguine. There have been big gold discoveries in this country. It is now firmly believed that all our land is auriferous, and the scoundrel who sold us this beggarly ranch has tried to upset our title. Thanks to your foresight, he was knocked out at the first round. So I may soon have big news for you. By Jove, won't it be a change if we both become rich! And won't we all have a time in Paris! However, I must not promise too much. I have been taught caution by repeated failures. Write by return, and say if this reaches you all right. "Your faithful friend, "SYDNEY H. CORBETT." "What do you think of that?" cried the detective, when Bruce had slowly mastered the contents of the letter. "Think! I am too dazed to think." "We can now learn all about him from America." "About whom?" "About Corbett, of course."
