"Well, when you do, spend a little of your time at the Walledup-Hysteria. It is a hotel with a population larger than that of most cities, with streets running to and from all points of the compass; where men and women eat under conditions that Lucullus knew nothing of; where there is a carpeted boulevard on which walk all sorts and conditions of men; where one pays one's bill to the dulcet strains of a string orchestra that woo him into a blissful forgetfulness of its size; and where, by pressing a button in the wall, you may summon a grand opera, or a porter who on request will lend you enough money to enable you and your family to live the balance of your days in comfort. In America men have been known to toil for years to amass a fortune for the one cherished object of spending a week in this Olympian spot, and then to be content to return to their toil and begin life anew, rich only in the memory of its luxuries. It was here that I spent my time when, some years ago, I went to the United States to solve the now famous Piano Case. You will remember how sneak thieves stole a grand piano from the residence of one of New York's first families, while the family was dining in the adjoining room. While in the city, and indeed at the very hotel in which I stopped, and which I have described, Pinkham's diamond stud disappeared, and, hearing that I was a guest at the Walledup-Hysteria, the owner appealed to me to recover it for him. I immediately took the case in hand. Drastic questioning of Pinkham showed that beyond all question he had lost the stud in his own apartment. He had gone down to dinner, leaving it on the centre-table, following the usual course of most millionaires, to whom diamonds are of no particular importance. Pinkham wanted this one only because of its associations. Its value, $80,000, was a mere bagatelle in his eyes. "Now of course, if he positively left it on the table, it must have been taken by some one who had entered the room. Investigation proved that the maid, a valet, a fellow-millionaire from Chicago, and Pinkham's children had been the only ones to do this. The maid and the valet were above suspicion. Their fees from guests were large enough to place them beyond the reach of temptation. I questioned them closely, and they convinced me at once of their innocence by conducting me through the apartments of other guests wherein tiaras of diamonds and necklaces of pearls--ropes in very truth--rubies, turquoise, and emerald ornaments of priceless value, were scattered about in reckless profusion. "'D' yez t'ink oi'd waste me toime on an eighty-t'ousand-dollar shtood, wid all dhis in soight and moine for the thrubble uv swipin' ut?" said the French maid.
