It was a long interview, and as toward its close the sounds of uproarious laughter penetrated to the ears of the loungers in the outer room, Van Vernet bit his lip with vexation. Evidently the Chief was not visiting his displeasure too severely upon his dilatory favorite. Vernet's cheeks burned as he realized how utterly he had failed. Not only had he heaped confusion upon himself, but he had not succeeded in lessening Stanhope's claim to favoritism by bringing upon him the displeasure of the Agency. While he sat, still tormented by this bitter thought, Stanhope re-entered the room, and walking straight up to Vernet brought his hand down upon the shoulder of that gentleman with emphatic heartiness, while he said, his eyes fairly dancing with mischief, and every other feature preternaturally solemn: "I say, Van, old fellow, how do you like conducting a Raid?" It was a moment of humiliation for Van Vernet. But he, like Stanhope, was a skilled actor, and he lifted his eyes to the face of his inquisitor and answered with a careless jest, while he realized that in this game against Richard Stanhope he had played his first hand, and had lost. "It shall not remain thus," he assured himself fiercely; "I'll play as many trumps as Dick Stanhope, before our little game ends!" * * * * * When Walter Parks returned from his two days' absence, and called at the office to receive the decisions of the two detectives, the Chief said: "You may consider yourself sure of both men, after a little.

And in order that they may start fair, after their present work is done, I have arranged that you meet them here to-night, and let them listen together to your statement." "I like the idea," said Walter Parks earnestly, "and I will be here at the appointed time." That evening, Vernet and Stanhope,--the former grave, courteous, and attentive; the latter cool, careless, and inconsequent as usual,--sat listening to the story of Arthur Pearson's mysterious death, told with all its details. As the tale progressed, Van Vernet became more attentive, more eager, his eyes, flashing with excitement, following every gesture, noting every look that crossed the face of the narrator. But Dick Stanhope sat in the most careless of lounging attitudes; his eyes half closed or wandering idly about the room; his whole manner that of an individual rather more bored than interested. "It's a difficult case," said Van Vernet, when the story was done. "It will be long and tedious. But as soon as I have found the man or men I am looking for, I will undertake it. And if the murderer is above ground, I do not anticipate failure." But Stanhope only said:
